Robot system
Provided is a robot system including a robot; a control device configured to control the robot; a portable teach pendant connected to the control device; and a teaching handle attached to the robot and connected to the control device, where the teach pendant is provided with a first enable switch configured to permit operation of the robot by the teach pendant, the teaching handle is provided with a second enable switch configured to permit operation of the robot by the teaching handle, and the control device enables operation of the robot by the teaching handle only when the first enable switch is in an off state and the second enable switch is switched to the on state, and enables operation of the robot by the teach pendant only when the second enable switch is in an off state and the first enable switch is switched to the on state.
GENERATING A ROBOT CONTROL POLICY FROM DEMONSTRATIONS COLLECTED VIA KINESTHETIC TEACHING OF A ROBOT
Generating a robot control policy that regulates both motion control and interaction with an environment and/or includes a learned potential function and/or dissipative field. Some implementations relate to resampling temporally distributed data points to generate spatially distributed data points, and generating the control policy using the spatially distributed data points. Some implementations additionally or alternatively relate to automatically determining a potential gradient for data points, and generating the control policy using the automatically determined potential gradient. Some implementations additionally or alternatively relate to determining and assigning a prior weight to each of the data points of multiple groups, and generating the control policy using the weights. Some implementations additionally or alternatively relate to defining and using non-uniform smoothness parameters at each data point, defining and using d parameters for stiffness and/or damping at each data point, and/or obviating the need to utilize virtual data points in generating the control policy.

ROBOT SYSTEM AND METHOD FOR CONTROLLING ROBOT
A robot system includes a robot including leading end, base, and multi-articular arm, and circuitry that controls the atm to move the end based on motion control program specifying transition over time of target position and posture of the end, the transition including correction target portion starting and ending in the transition; controls the arm to move the end in response to guided manipulation applying external force to the robot while the circuitry controls the arm; obtains relative command information based on the target position and posture at start of the correction portion and specifying the target position and posture at points in the correction portion including start and end in the correction portion; and controls the arm to move the end from the position and posture based on the information, beginning at time when movement of the arm controlled by the circuitry in response to the manipulation has ended.
ACTION TEACHING METHOD FOR ROBOTIC ARM AND GESTURE TEACHING DEVICE
An action teaching method is provided for teaching a robotic arm of a robotic arm system through a gesture teaching device. In a step (a), a touch condition of a user's finger is sensed by the touch sensing unit. In a step (b), a sensing result of the touch sensing unit is transmitted to an identification unit, so that a touch information is identified by the identification unit. In a step (c), the touch information is transmitted to a teaching unit, so that the teaching unit actuates a corresponding operation of the robotic arm system according to the touch information. In a step (d), an operating result of the robotic arm system is shown on a display unit, so that the user judges whether the operating result of the robotic arm system is successful through the display unit.
Robot system including force-controlled pushing device
A robot system including a force-controlled pushing device which causes, when a robot is guided and moved, an object provided at a tip end of the robot to be brought into appropriate contact with another object. The robot system includes the robot, the force-controlled pushing device, a robot operation input measuring part, a robot movement command calculating part, a pushing direction setting part, a target pushing force setting part, a force measuring part, and a force-controlled pushing device movement command calculating part. The pushing direction setting part sets a pushing direction of the force-controlled pushing device, based on at least one of: the position/orientation of the first object; a force-controlled pushing device movement command for moving the first object; the position/orientation of the movement mechanism part of the force-controlled pushing device; the position/orientation of the robot; and a robot movement command for moving the robot.

CONTROL DEVICE, CONTROL METHOD, AND RECORDING MEDIUM
A control device which synchronizes and controls a master device and a slave device at a fixed period when the number of axes of the master device differs from the number of axes of the slave device is provided. A computing unit includes a coordinate transformation unit which performs coordinate transformation from a coordinate system of the master device into a coordinate system of the slave device for a command value for each axis or a measured current value of each axis of the master device at a fixed period and a synchronization computing unit which performs synchronization computation for maintaining the position of the master device and the position of the slave device in a predetermined corresponding relation for coordinate transformation result values obtained through the coordinate transformation. In this manner, a command value for each axis of the slave device is obtained.
