A calculation device for calculating the permissible value of external forces acting on a robot or workpiece, and a robot control device.
By detecting external forces using computing devices and force sensors, the robot's position and posture are adjusted to control the external forces within permissible values. This solves the problems of prolonged operation time and low productivity caused by excessively low target values of external forces in existing technologies, and enables highly efficient workpiece insertion operations.

AI Technical Summary
In the prior art, during the workpiece handling process, in order to precisely adjust the position and posture, setting the target value of external force too low leads to a longer operation time, and when the external force exceeds the allowable value, the drive needs to be stopped, which affects productivity.
The system uses a computing device to calculate the allowable external force value of the robot device or workpiece, and uses a force sensor to detect the external force. The robot's position and posture are adjusted to control the external force within the allowable value. Combined with the motion control unit, the robot's movements are controlled to avoid overloading of structural components.
This technology enables the reduction of workpiece fitting time, improvement of production efficiency, and avoidance of structural component damage caused by excessive external forces, without affecting the normal operation of the robot device.
