    The World Robot Summit (WRS) Industrial Robotics Category tries to evaluate the performances of assembly robot systems using a task board. The task board comprises an assembly board (task board or board) and a set of parts assembled to the board. Utilizing an appropriate task board expects to facilitate the development of assembly robot systems. This paper examines the components necessary for the design of the task board through the results and analyzes of the task board competition in the WRS 2020 (held in September 2021). The task board will serve as a benchmark in developing an assembly robot system that can assemble the belt drive unit, an assembly model for the WRS 2020 assembly competitions. The success rate of each part of the competition and the correlation with assembly competitions reinforces the validity of the task board design. This paper describes that the WRS 2020 task board had a larger correlation with the belt drive unit used in the assembly competitions than that of the WRS 2018 (0.54 vs. 0.29). The design in the WRS 2020 is more appropriate than that in the WRS 2018 as a benchmark for assembling the belt drive unit.

    The World Robot Summit (WRS) is a robotic 'challenge and exposition' organized by the Japanese government to accelerate social implementation, research and development of robots working in realistic daily life, society, and industrial fields. In this paper, we introduce a robot competition of the Industrial Robotics Category of the WRS, called 'Assembly Challenge', which is organized by the WRS Industrial Robotics Competition Committee in order to promote the development of the next-generation production systems that can respond to new production demands in agile and lean manners. After the pre-competition held in Tokyo in October 2018, the main competition, the WRS 2020, was originally scheduled to be held in Aichi (partly in Fukushima) in 2020, which was also the Olympic year. However, due to the pandemic of COVID-19, the event was postponed, and the competition was actually held in Aichi in September 2021. In this paper, we introduce the contents and results of the WRS 2020 and analyze the results. We would also like to summarize the 5-year project since 2017 and discuss the outcomes of the WRS.

    This paper describes a fish-like robot with a deformable outer shell fabricated using a silicone mold. Based on the difference in the contact condition between the serial-link robot and the shell, the fabrication methods are classified into embedded type and skin type. This study analyzes the mechanical properties of embedded and skin-type underwater robots from the viewpoint of material mechanics. A low-torque motor can sufficiently drive the skin-type underwater robot if the friction coefficient and pressure between the skin and the link are appropriately selected. Furthermore, the outer skin of the fish-like robot can be easily fabricated by defoaming in the chamber of a vacuum-packaging machine. Finally, the performance of the skin-type robot in air and underwater was assessed through several experiments.

    This report describes a numerical and experimental study of a posture control device based on a movable float for portable underwater robots. We numerically analyzed the static stability using a stability curve and allowable spatial range of a center-of-gravity shift caused by a payload shift or manipulator configuration. Further, we proposed a feedback controller based on direct pitch and roll signals to change and maintain robot posture. We tested the feedback control using a numerical simulator and conducted experiments in a water tank using two portable underwater robots to demonstrate the effectiveness of the movable float device and proposed controller. The results of the field experiments showed that the device and proposed controller can be employed for effective underwater operations of portable underwater robots.

    This manuscript describes a pressure sensor equipment for underwater robot external attachment. It is difficult to add sensors to many underwater robots. Most pressure sensors have a diaphragm plate, and the pressure sensor must be exposed to the environment to deform the diaphragm plate. Therefore, to add a pressure sensor to an underwater robot, it is generally necessary to redesign both the outer shell and the robot's inner structure. To solve this problem, we propose encapsulating a pressure sensor in a plastic film bag. Vacuum packaging technology is applied to fabricate the sensor equipment. This technique is called the robot packaging method, and it is possible to fabricate the sensor equipment rapidly and inexpensively. This manuscript shows experimental results that it is necessary to encapsulate a sufficient amount of insulating fluid in the plastic film bag to fabricate the pressure sensor equipment by the robot packaging method.

    This manuscript describes the modeling of a serial link robot covering with a thin, flexible film. By covering a serial link robot with a plastic film, the robot can manipulate daily goods such as foods and clothes cleanly. However, the mechanical properties of the serial links covering the film have not been clarified. In this manuscript, we discuss the fundamental mechanical characteristics, whether the film and the link should slide or not. We assume that the film is modeled as a beam, and analyze the static mechanical characteristics from the viewpoint of material mechanics. As a result, we find the robot can rotate even in a small DC motor by filling an appropriate volume of an insulating fluid. We evaluate the validity of the analyses experimentally through the prototype fabricated by the robot packaging method.

  • Attitude control mechanism for underwater robot with flexible plastic film body
    Mizuho Shibata; Norimitsu Sakagami
    Proceedings of the International Offshore and Polar Engineering Conference 2015- 558 - 563 2015年 
    This paper describes an attitude control mechanism for an underwater robot with a flexible plastic film body. Insulating fluid was poured into a packaging resin film, the outer layer of the robot, to improve its pressure resistance under water. The attitude control mechanism consisted of an arrangement of the insulating fluid and floating blocks inside the robot. The attitude control mechanism will allow three-dimensional non-holonomical movements of the robot under water.

    A portable underwater robot that has a high pressure resistance is required for easy observations in wide area. In this manuscript, we discuss the fabrication and design of a fish-like underwater robot that the outer body is composed by a flexible thin plastic film. Force generated by the differential pressure between inside and outside of the robot is zero due to the flexibility. Therefore, the plastic film of the robot does not ideally break under high pressurized environment. The entire body of the robot is fabricated by a vacuum packaging machine. We call this fabrication robot packaging. The design guide of our fish-like robot depends on the density of insulating fluid containing within the body. Even the fluid is lighter or heavier than water, we can construct the fish-like robot that is at neutral buoyancy

    The locomotion of underwater robots depends on their shapes. Underwater robots for inspecting undersea structures must not only move long distances but must rotate during inspection. We propose using an underwater robot that moves translationally and rotationally by altering its shape. In this paper, we introduce a deformable twisted trigonal prism tensegrity structure as a robot and evaluate its use as an underwater robot through several simplified models and experimental results.

    We discuss an unfolding of fabrics by robotic hands. During unfolding, humans usually allow their fingertips to slip on the fabric surfaces, referred to as a pinching slip motion. We define this motion using differential geometry coordinate. In this motion, the weight of the fabric generates relative movement between the moving fingertips and the fabric, and then, the edges of the fingertips are in contact with the hem of the fabric. We confirm experimentally that the success rate depends on fingertip shapes and grasping force of a robotic hand during the motion. The range between fingertips can be selected widely when fingertips with circular edges are applied. Finally, we demonstrate a fabric unfolding experimentally.

    To analyze the stability of dynamic control through asoft interface-the viscoelastic material between a manipulating finger and a manipulated object- we model dynamic control through the soft interface in continuous-discrete time. We then formulate dynamics using a modified z-transform in continuous-discrete time for feedback and feedforward control. We show that system stability depends on the viscoelasticity of the soft interface for feedback control. The relationship between material viscosity and sampling time in critical stability is not monotonous, a phenomenon we analyze by root locus. We compare stability analysis by the modified z-transform, simulations based on the Runge-Kutta method, and a regular z-transform, demonstrating that the relationship is specific to a continuous-discrete time.

    A feature of soft object manipulation in free space is coupling of motion and deformation of the soft object. Herein, we formulate simultaneous control of position and deformation of a viscoelastic object. We show that the stability of the system depends not only on control laws and parameters but also on physical parameters of the object, and that positive feedback gain within a certain range stabilizes PID controlled systems; outside this range, the object cannot be stably controlled since the object is movable. We also validate the stability of the system for control inputs and mapped manipulated and positioned points. The positioned points converge to their desired positions using the mapping based on closest relationship between the positioned and manipulated points. We show that both the viscosity of a soft object and the damping component of the control law are essential for stability when a force is used as a control input.

    We analyze the stability of dynamic object manipulation through asoft interface, the viscoelastic material between a manipulating finger and manipulated object. First, we model a dynamic object manipulation system through a soft interface. The system is described in continuous-discrete time. Second, we formulate the dynamics using the modified z-transform in the continuous-discrete time system for feedback and feedforward control. Thus, we show that the stability of the system depends on viscoelasticity of the soft interface for feedback control. In particular, we point out that, in critical stability, the relationship between material viscosity and sampling time is not monotonous. We also analyze this phenomenon by the root locus method. Next, we compare the stability analysis by the modified z-transform and a regular z-transform. Thus, we demonstrate that the relationship is specific to the continuous-discrete time system. Finally, we confirm the relationship experimentally.

    This manuscript describes a tensegrity-type underwater robot with a transforming mechanism. The robotic body is composed of tensegrity structure with plastic pipes (struts) and a rubber band (deformable strings) so that the robotic body has deformability. A winding unit attaching to one tip of the tensegrity structure can transform the body of the robot. The winding unit includes a planetary gear. Winding the gut fixed on the rotary shaft of the water-proofing motor transforms the shape of the deformable tensegrity structure. In this manuscript, to evaluate the performance of the transforming mechanism, we investigate the fluid characteristics of the robot against constant water flow. Based on results, we find that transforming the robot with the winding unit alters its translational performances because the projecting area decreased for transforming the robotic body.

    This paper presents the modeling and numerical simulation of a serial link robot fabricated by robot packaging method. First, we derive the equations of motion of a laminated robot made of a rigid serial link and a plastic film. We assume the plastic film as a closed-loop link structure with passive joints. The rigid serial link connected with a motor-actuated joint moves the closed-loop link structure (film) with passive joints. We numerically investigate the influence of the flexural rigidity of the plastic film on the motion of the rigid link.

    In this study, an exoskeletal biped robot which consists of flexible members is proposed. The mass and height of the robot are 0.9 kg and 320 mm. The exoskeletal flexible robot walks using static walking techniques. We evaluate the walk through the step length and speed of the robot. We also investigate the impact resistance of the robot through several experiments. Prom results of drop experiments to the robot by weights, the robot is not broken out up to 8.2 J of potential energy. From results of drop experiments of the robot to floor, the robot is not broken out up to 850 mm height.

    This manuscript describes a robot fish, the surface of which is composed of a exible thin plastic film. Its internal mechanism, including an actuator (e.g. a servomotor), is encapsulated in the plastic film by a vacuum packaging machine. This plastic film has electromagnetic wave-transmitting properties, allowing sensors, wireless charging modules, and communication devices to be arranged within the device. To simplify the waterproofing and pressure resistance properties of the robot, the inner portion of the robot fish is filled with insulating fluid, such as industrial oil. The transmission performances of these devices, which utilize electromagnetic waves, may worsen due to the tendency of water or insulating fluids to attenuate the electromagnetic waves. This study therefore experimentally investigated the transmission performance of these devices, while taking into account the effects of water or insulating fluid. These devices were subsequently applied to our sh robot; enabling us to verify its performance by using infrared sensors to assess its autonomous locomotion.

    This paper reports the development and experiments of an underwater 6-DOF gripper robot. The developed gripper robot is a human-portable remotely operated vehicle (ROV) that weighs approximately 31 kg in air. The most important feature of this robot is that it can grasp cylindrical objects of 50-500 mm diameter, and handle them in 6 DOF. We also developed a dedicated operating device to use the gripper robot effectively. To reduce the operator burden during underwater tasks, several software functions of the operating device are provided, such as thrust allocation, depth control, and pitch angle control. Experiments in a test tank demonstrated the motion performance of the developed robot and the effectiveness of the operating device.

    In this paper, we describe the rolling of a tensegrity robot driven by a set of pneumatic soft actuators. Tensegrity is a mechanical structure consisting of a set of rigid elements connected by elastic tensional elements. Introducing tensegrity structures, we are able to build soft robots with larger size. Firstly, we show the prototype of a six-strut tensegrity robot, which is driven by twenty-four pneumatic McKibben actuators. Second, we formulate the geometry of the tensegrity robot. We categorize contact states between a six-strut tensegrity robot and a flat ground into two axial symmetric contact and planar symmetric contact.

    This paper presents ship hull inspection using a small underwater robot with a mechanical contact mechanism. We propose a mechanical contact approach in order to conduct ship hull inspection, and develop a contact mechanism, hand-eye vision system, and stereo camera system. The proposed contact mechanism enhances the position and orientation keeping performance of small underwater robots. The developed hand-eye system and stereo camera system provide fine and detailed vision information for inspection. In this paper, we numerically analyze the position and orientation keeping performance of a small underwater robot with a mechanical contact mechanism, and conduct fundamental experiments in a test tank. Additionally, we inspect a ship's hull in a port as a field experiment. © 2012 IEEE.

    This paper presents a method of fabric manipulation utilizing contacts with rigid environment. During its manipulation, the fabric can be replaced and deformed favorably by the contacts. We first show that a single-handed manipulator can deal with a rectangular piece of fabric by utilizing the environment. We discuss in detail a motion involving placing, one of the basic tasks in fabric manipulation. We also describe a wiping motion, involving ways to deform and replace fabrics, as an application of fabric manipulations utilizing contacts with rigid environment. © 2012 IEEE.

    As described in this paper, we propose an attitude control system for underwater vehicle/manipulator systems (UVMSs) based on control of the position of the center of buoyancy with respect to the center of gravity. Control of the center of buoyancy is accomplished using movable float blocks. The attitude control system is useful to control the pitch angle of UVMSs to enhance their performance and to improve their efficiency of underwater operations. A UVMS that has two 5-degree-of-freedom (DOF) manipulators was developed to verify the effectiveness of the proposed attitude control system. This paper presents a numerical study and some experimental results obtained using the UVMS with the attitude control system. We experimentally confirmed that the proposed system can change the pitch angle of the vehicle between -120 and +105 deg. In another experiment, attitudemaintenance control was conducted. Results show that the proposed system can maintain the vehicle's horizontal attitude during motion of the manipulators. ©2010 IEEE.

    In this paper, we describe the development of a human-sized remotely operated vehicle (ROV) with dual-arm. The developed ROV was designed to perform biological researches, geological researches and archaeological explorations in Lake Biwa, the biggest lake in Japan. This ROV has two distinguishing characteristics: one is a dual-manipulator system and the other is an attitude control system. The size of the manipulators is related to the size of a human arm so that the ROV can do work that human divers usually do using the arms. The attitude control system is capable of keeping the vehicle in a horizontal plane, and purposely changing the vehicle attitude angle. Additionally, we developed a new master-slave controller system for this ROV. Some fundamental experiments in a diving pool were performed in order to test the capabilities of the developed ROV. After those experiments, a field trial was conducted in Lake Biwa and the ROV carried out some works at a depth of about 10-20 meters. © 2010 IEEE.

    We describe here the development a joint mechanism for underwater robotic manipulators. Arms of underwater robots require small-scale bodies and high waterproofing properties. In most of underwater robots, electric motors are used as actuators to drive the robotic arm/arms, but using electric motors for underwater manipulators may be problematic due to the size/weight of the robotic arm and need to waterproof the electric motors. We develop a joint mechanism composed of combinations of rigid and flexible members, which can be deformed by a prismatic actuator fixed onto two rigid parts. We utilize a leaf spring as the flexible joint and a McKibben actuator driven by water hydraulic pressure as the prismatic actuator. The number of members in this mechanism is smaller than that of a mechanism composed of a combination of one pulley and one coil spring. One advantage of this mechanism is the avoidance of gears, thus eliminating sliding parts from the joint. ©2010 IEEE.

    In this paper, we present the design and development of an attitude control system for a human-sized ROV (Remotely Operated Vehicle) with a dual-manipulator system. The main operations of the ROV are sampling operations for biological researches, geological researches and archaeological explorations in Lake Biwa, the biggest lake in Japan. In order to achieve these operations, we propose an attitude control system and explain the availability of the proposed system in this paper. For the design of the attitude control system, simulation analysis was conducted. Based on the analysis, a pitch angle control system was designed and developed as the prototype of the attitude control system. An experiment was conducted in a test tank to demonstrate the effectiveness of the proposed system. The result shows that the developed system is useful for pitch angle control of the ROV. ©2010 IEEE.

    Most robots with manipulators used in fieldwork use operating devices that are large and complicated, requiring a large system such as a flight cockpit and several operators to move the arms/arm and body of the robots separately. These robots may be more efficiently manipulated using small-scale operating devices, able to be manipulated by a single operator. We have developed an operating device composed of joysticks mounted onto link mechanisms, to manipulate the movement of the robot body. In addition, this device incorporates multi-DOF manipulator-like link structures, which can be intuitively operated by the operator. We also evaluated the operability of this device, as determined by the operator's mental workload and the physical configuration of the operator's hand. © 2010 IEEE.

    This paper describes a representation method of fabric manipulation, referred to as virtual rope theory. In this theory, fabric manipulation by robotic grippers is considered equivalent to manipulation of a deformable rope. Based on the theory, we define various fabric manipulations; we can judge the success or failure of these manipulations quantitatively. We define a fabric manipulation using differential geometry coordinates. We confirm the applicability of the virtual rope theory by experimental unfolding of a fabric.

    This paper presents a mechanical system that achieves grasping, unfolding, and placing motion of fabrics in series. Fabric setting process by human consists of grasping, unfolding, and placing motion of fabrics. We realize the setting process using a single-armed robot and a four degrees of freedom gripper hand. The robotic gripper wrinkles the fabric to make a grasping area using residual deformation of the fabric. In unfolding motion, we introduce a pinching slip motion, that fingertips slip on the fabric surface with grasping, similar to human unfolding motion of fabrics.

    The paper presents dynamic unfolding of fabrics by pinching slip motion. By keeping the textile in contact with robot fingertips, the dynamic unfolding is done successfully in horizontal direction. The success rate depends on fingertips shape. The grasping force is important for dynamic unfolding of textile by pinching slip motion. We simulate the contact force between fingertips and the fabric. Here, we assume that the contact force is described by contact between fluid and an obstacle in duct. We confirm validity of the experimental results using computational fluid dynamics.

    This paper represents a stability analysis of a non-collocated mechanical system. Non-collocated mechanical systems include a visual feedback control of a flexible arm and an indirect simultaneous positioning of fabrics. Coefficient matrices of the dynamic equation are asymmetry in a linear non-collocated mechanical system. We analyze the stability of a non-collocated system by a particle model and a Lyapunov function. In derivative (D) control, the asymptotic stability depends on viscous modulus and whole length of a soft object not to depend on division number of a particle model. We also confirm that a pair of gains stabilize the system in position and derivative (PD) control.

    We present a link mechanism with a loosely coupled mechanism (LCM), modeled on a human joint. A viscoelastic object functions as a cartilaginous area and soft actuators as muscles. The link of an LCM has high compliance with soft materials, additionally bends smoothly as a human joint. We made an LCM using shape memory alloy (SMA) actuator bundles to regulate the link angle. Due to large generative force of actuator bundles, we have better response in angle control. Although it is impossible to set a high gain for each SMA, the whole system using actuator bundles can realize high gain feedback in angle control.

    We introduce a robotic prototype of an arm with a loosely coupled joint, modeled on the human joint. A viscoelastic object functions as cartilage and soft actuators as muscles. First, we show that although viscoelastic object affords smooth movement owing to shift in the center of rotation, the repeat accuracy of the joint is poor under open-loop control. The repeat accuracy was much improved by visual feedback. Under P control, the prototype was shown to be highly robust against mechanical disturbance owing to its good mechanical compliance.

    We describe here a mechanism for controlling angles of a human-like joint using length sensors in three-dimensional (3D) space. This joint mechanism, which is called a loosely coupled mechanism, includes a viscoelastic object and soft actuators in place of the cartilage and muscles of a human arm. To confirm motion of the link using one length sensor, we constructed a prototype of the mechanism in two-dimensional (2D) space. Based on this prototype, we constructed a 3D loosely coupled mechanism with length sensors, and we were able to control two projecting angles of the 3D prototype. In addition, we propose an appropriate method of measurement to reduce errors in measurement due to the length sensors. Using this method, we found that, for each projecting plane, the errors were less than 1.0 deg in our 3D prototype.

    One of features of soft object manipulation is motion during deformation of the soft body. We analyze the stability of soft object manipulation by simultaneous control of motion and deformation. We model and formulate manipulation by simultaneous control of the motion and deformation of soft object. We then use the symmetric linear mass-damper-spring model for a simple analysis of its dynamical behavior. Second, we analyze the stability of the system. Thus, we show that an adequate feedback gain stabilized the system in PID control. This adequate feedback gain ranges between two positive values. The object cannot be stably controlled at too high a gain; neither can, it be regulated at too low a gain since the object is movable. Furthermore, we unravel the features of soft object manipulation by simultaneous control of motion and deformation.

    This paper focuses on a control of a joint including a viscoelastic object. The viscoelastic object corresponds to a cartilage of a human joint. This joint is referred to as a loosely coupled joint. First, we model a viscoelastic object of the cartilaginous area of a loosely coupled joint to formulate dynamic equations of the link. Based on the dynamic equations, we simulate the link motion to analyze the stability of the link in its angle control. Finally, we construct a prototype to experiment it in angle control of the link. From these results, we find the angle of the link by I control both in experiment and in simulation.

    We analyze the stability of dynamic control on contact with a soft interface, the viscoelastic material between a manipulating finger and manipulated object. First, we model a dynamic control system on contact with a soft interface. The system is described in continuous-discrete time. Second, We formulate the dynamics using the modified z-transform in the continuous-discrete time system for feedback and feedforward control. Thus, we show that the stability of the system depends on viscoelasticity of the soft interface for feedback control. In particular, we point out that, in critical stability, the relationship between material viscosity and sampling time is not monotonous. Next, we analyze this phenomenon by the root locus method. Finally, we compare the stability analysis by the modified z-transform, simulations based on the Runge-Kutta method, and a regular z-transform. Thus, we demonstrate that the relationship is specific to the continuous-discrete time system. © 2005 IEEE.

    本論文では, 指先に柔軟体を有するハンド用いて把持力制御を行った。対象物と指の間が面接触となるため, 力の計測に分布圧センサを用いた。また, バネ・マス・ダンパー系で柔軟指を用いたハンドリングをモデル化し解析を行った。

    現在の産業界ではベルトコンベア上を流れる物体など平面運動物体を把持する場合, ティーチングを用いて行うことが多い。しかし, ティーチングでは流れてくる物体によって位置・姿勢・速度が変化するような場合には対応することが出来ない。そこで, 本報告ではビジュアルフィードバックを利用して物体の位置・姿勢・速度を検出し, ビデオフレームごとに速度軌道を計画しなおすことにより平面運動物体をロバストに把持する手法を提案する。
