The invention relates to a robot manipulator, wherein a braking device arranged on at least one of the joints of the manipulator is activated by a control unit in order to generate such a residual torque that a maximum torque is not exceeded at the joint, and the residual torque is determined on the basis of sensor determination and/or estimation of the torque currently present at the joint, wherein the estimation is based on a measure, multiplied by a first predefined factor, of a gravitational influence acting on the at least one of the joints, or is based on a dynamic model of the robot manipulator, the dynamic model having the gravitational influence, wherein the control unit determines the gravitational influence on the basis of a joint angle vector with joint angles between the at least one of the joints and a distal end of the robot manipulator.

A system for performing a dental procedure includes a hand piece having a robot arm that extends along a first axis, and a medical tool coupled with a distal end of the robot arm. The system includes a first gimbal coupled with the robot arm for rotating the robot arm and the medical tool about the first axis, a second gimbal coupled with the robot arm for tilting the medical tool up and down relative to the first axis, and a third gimbal coupled with the robot arm for moving the medical tool up and down along a second axis that is perpendicular to the first axis.

A manipulator for a surgical instrument may comprise an instrument holder coupled with the surgical instrument and rotatable in a plane that passes through a remote center. The manipulator may also comprise a linkage assembly coupled to the instrument holder to limit motion of the instrument holder to rotation about an axis that intersects the remote center. The linkage assembly may comprise a first linkage arm comprising first and second pulleys. Each pulley may comprise first and second drive tracks which are substantially co-planar. The first linkage arm may also comprise a first drive member section extending between the first drive tracks of the pulleys and a second drive member section extending between the second drive tracks of the pulleys. The first drive member section may be wound around the first pulley in a first direction and the second drive member section may be wound around the first pulley in an opposite direction.

A substrate conveyor robot includes a guide rail cover arranged on a lateral side of the guide rail to cover an upper part of a guide rail that is exposed when an up-and-down mover moves downward. The base link includes the guide rail cover.

A manipulator (110) for e.g. gait training is constructed from an Evans mechanism with an additional degree of freedom to provide a two dimensional workspace.

A large manipulator includes a folding-out articulated mast with a turntable rotatable about a vertical axis and with a plurality of mast segments. The mast segments are each pivotable on articulated joints about articulated axes relative to an adjacent mast segment or the turntable. The at least one mast is formed by a hollow structure of wall elements connected with each other. At least one of the wall elements includes a recess region with a recess. A material thickness of the at least one wall in the recess region is less than a material thickness of the at least one wall element outside the recess region.

An operation device for a link actuating device (51) is provided with a target value input unit (57) having a height direction target value input portion (57z) that allows input of a movement amount in a height direction or a coordinate position in the height direction, which causes the distal end posture of the link actuating device (51) to be changed only in the height direction along a central axis of a proximal end side link hub (12). Input converter (58) is provided to calculate, by using an inputted value, a target distal end posture of the link actuating device (51). The Input converter (58) further calculates a command operation amount of each actuator (53) from the result of the calculation, and inputs the command operation amount to the control device (54).

The disclosure relates to an articulated robot having a serial kinematic mechanism for positioning an end effector, the kinematic mechanism having at least one part kinematic mechanism with a robot joint, with a robot limb mounted upstream of the robot joint, and with a robot limb mounted downstream of the robot joint. The at least one part kinematic mechanism has a linear drive, with a drive element, and a coupler with two coupler joints which are spaced apart from one another along the coupler extent, wherein the linear drive is arranged on a first robot limb of the part kinematic mechanism, and wherein the coupler is articulated on one side on the drive element of the linear drive and on the other side on the second robot limb of the part kinematic mechanism, spaced apart from the geometric axis of the robot joint of the part kinematic mechanism.

A computing system includes actuator control logic configured to generate and send control signals to an actuator of a mobile machine configured to drive direction and speed movement of a linkage on the mobile machine. The computing system also includes a control map generator system configured to receive sensor signals indicative of the direction and speed movement of the linkage on the mobile machine, and, based on the received sensor signals, generate a control mapping that maps the control signals to the direction and speed movement of the linkage of the mobile machine.

A robot has a vertical 6-axis articulated arm having an offset arm having a fifth axis and length link, and mutually linking fourth and sixth axes. The fourth and sixth axes shaft centers are parallel. The articulated arm has a head portion designated as a control point. A position and an orientation targeted to the control point is processed by an inverse transform to calculate angles of the axes. A provisional target position of the sixth axis is obtained by subtracting the link length from a target position of the sixth axis. The link length to the provisional target position is given zero to perform the inverse transform process. Processed results are evaluated. Until a difference between a calculated sixth-axis angles and provisionally decided sixth-axis angles becomes equal to or less than a predetermined value, processes started from the angle provisional decision of the sixth axis are repeatedly performed.
