Abstract: A tool calibration apparatus for a robot manipulator having a tool is disclosed. The tool calibration apparatus comprises a base, an X-axis measurement device, a Y-axis measurement device and a Z-axis measurement device. Each of the X-axis measurement device, the Y-axis measurement device and the Z-axis measurement device comprises a measuring plate and a sensor. The measuring plates of the X-axis measurement device, the Y-axis measurement device and the Z-axis measurement device move in a direction along the X-axis, Y-axis, and Z-axis, respectively. The sensors of the X-axis measurement device, the Y-axis measurement device and the Z-axis measurement device measure a displacement of the corresponding measuring plate. According to the displacements, information of a tool center point of the tool is acquired so as to calibrate the tool center point.

Abstract: A three-dimensional measuring device includes a ball-shaped structure, an X-axis measuring module, a Y-axis measuring module and a Z-axis measuring module. The ball-shaped structure is moved and/or rotated in response to a movement of a movable object. The X-axis measuring module includes a first measuring structure and a first position sensor. The first measuring structure is movable along an X-axis direction and contacted with the ball-shaped structure. The Y-axis measuring module includes a second measuring structure and a second position sensor. The second measuring structure is movable along a Y-axis direction and contacted with the ball-shaped structure. The Z-axis measuring module includes a third measuring structure and a third position sensor. The third measuring structure is movable along a Z-axis direction and contacted with the ball-shaped structure.

Abstract: An electric gripper is disclosed and includes a carrier, an actuator, two dual-lever assemblies and an angle sensor. The actuator is disposed on the carrier and includes a sliding portion. The two dual-lever assemblies are disposed on the carrier and located at two opposite lateral sides of the sliding portion. Each of the two dual-lever assemblies includes a driving lever, a limiting lever and a gripping piece. The driving levers are staggered to each other. The limiting levers are staggered to each other. When the sliding portion slides a first distance in the first direction, the sliding portion drives the driving levers to rotate an angle, and the gripping pieces move toward each other to displace a second distance in a second direction. The angle sensor is disposed on the carrier and configured to measure the angle, to correspond to the first distance and the second distance.

Abstract: A brake release device and a robot manipulator employing the same are provided. The robot manipulator includes a housing and a brake element. The housing defines an inner space and has an opening, and the inner space is in communication with a space outside the housing through the opening. The brake element is disposed within the inner space. The robot manipulator stops or is allowed to actuate according to a position of the brake element. The brake release device is connected with the brake element. The brake release device is partially located in the inner space, and the brake release device partially penetrates through the opening and is exposed from the housing. When the part of the brake release device exposed from the housing is moved by an external force so as to drive the brake element to move synchronously, the robot manipulator is allowed to actuate.

Abstract: A tool driving module for a robot manipulator comprising an end-shaft is disclosed. The tool driving module comprises a connection part, a motor driving module, a driving arm and a tool fixing bracket. The connection part comprising a combination bracket is coupled with the end-shaft. The motor driving module is coupled with the combination bracket. The driving arm is connected with the motor driving module, and driven by the motor driving module to rotate. The tool fixing bracket is connected with the driving arm for mounting a tool thereon. The tool fixing bracket and the tool are driven by the driving arm to rotate synchronously, and a tool center point of the tool and an extending line of an axis of the end-shaft are at a common point via the rotation of the tool.
