Latest Patents

Yokoshima's latest patents include a servo control system and a damper device for precision assembling robots. The servo control system allows for smooth and safe control of a control object from an arbitrary stop position to a target position. It features a detector for absolute position detection and an observer for monitoring state values such as position and velocity. This innovative system calculates initial state values based on the control object's stop position, enabling effective digital processing through sampling mode operation.

The damper device for precision assembling robots addresses the issue of residual vibrations in robot arms. It is designed to absorb vibration energy, thereby enhancing the rigidity of the arm. The device consists of a cylindrical weight member and a columnar rubber member, with a metallic rod inserted to control the dampening factor. This invention prevents assembly failures caused by positioning errors and impacts during operation.
