Robot arms and methods of controlling robot arms. In an example, a hand control is located on a robot arm and provides translation and/or rotation control of actuators that may for example rotate in unison. In another example, a hand control on a robot arm is also provided at an end effector, which may control actuators in the robot arm for example by having the actuators rotate together or oppositely in unison. In a further example, a hand control situated on a robot arm between actuators controls upstream and downstream actuators with different control strategies. In a master slave example, actuators in a master robot control actuators in a slave robot, and the actuators may be provided at an angle and be arranged to hold position in normal operation when unpowered. Nonbackdrivability is also provided by providing sufficient friction between stator and rotor in actuators of a robot arm. In a Scara robot, a fixed part of a base is secured to a floor, while a moving end is supported by a bearing element.

As an expert gives instructions to cause movements of their own hands transferred directly as tactile force sense while perceiving surrounding information of a collaborator on a real-time basis and watching the collaborator's line-of-sight end and movements of the collaborator's hands, the collaborator indirectly receives the instructions of the expert's manual skills, which are the expert's tacit knowledge, on a real-time basis while sharing realistic sensations with the expert who is at a remote location when the collaborator performs an act of working with their own hands.

A manipulator system configured to perform a work to a workpiece being moved by a moving device, includes a robotic arm, having one or more joints and to which a tool configured to perform the work to the workpiece is attached, an operating device configured to operate the robotic arm, a first imaging means configured to image the workpiece, while following the movement of the workpiece, a second imaging means fixedly provided in a work area to image a situation of the work to the workpiece, a displaying means configured to display an image imaged by the first imaging means and an image imaged by the second imaging means, and a control device configured to control the operation of the robotic arm based on an operating instruction of the operating device, while detecting a moving amount of the workpiece being moved by the moving device and carrying out a tracking control of the robotic arm according to the moving amount of the workpiece.

A haptic feedback device includes: a first feedback apparatus, including: a fixed platform, a movable platform, a ring disposed on the movable platform, and a power unit disposed on the fixed platform and connected to the movable platform. The power unit is configured to obtain a first control signal generated by a controller and output torsion according to the first control signal. The movable platform is configured to be driven by the torsion to move relative to the fixed platform. The ring is configured to provide feedback force as the movable platform moves, to implement haptic feedback.

A robot system according to the present disclosure includes a robot installed in a work area, a manipulator configured to be gripped by an operator and manipulate the robot, a sensor disposed at a manipulation area and configured to wirelessly detect positional information and posture information on the manipulator, and a control device which calculates a locus of the manipulator based on the positional information and the posture information on the manipulator detected by the sensor, and operates the robot on real time.

A hand controller for enabling a user to perform an activity and method for controlling a robotic arm is provided. The hand controller includes a bar with a grip and a plurality of motors to provide a force feedback to the user in response to the movement of the plurality of mechanical arms. The method involves receiving input corresponding to the manipulation of a bar and providing a force feedback in response to the movement of the plurality of mechanical arms.

A teleoperated robotic system that includes master control arms, slave arms, and a mobile platform. In use, a user manipulates the master control arms to control movement of the slave arms. The teleoperated robotic system can include two master control arms and two slave arms. The master control arms and the slave arms are mounted on the platform. The platform can provide support for the master control arms and for a teleoperator, or user, of the robotic system. Thus, a mobile platform can allow the robotic system to be moved from place to place to locate the slave arms in a position for use. Additionally, the user can be positioned on the platform, such that the user can see and hear, directly, the slave arms and the workspace in which the slave arms operate.
