Abstract

A movable miniature robot system for the precise job of microchemico-electric system is disclosed. Its micromovement locating unit is arranged in the macromovement locating unit. The transition connecting plate is fixed above said micromovement locating unit and to the top ends of vertical connecting posts. Its torque motor is fixed to said macromovement locating unit. Its advantages are small size, light weight, modular design, and high adaptivity. Its highest speed and locating precision are 50 mm/s and 0.1 mm for macromovement and 0.5 mm/s and 0.1 micron for micromovement.

Description

technical field [0001] The present invention relates to a robot system. Background technique [0002] With the continuous development of micro-electromechanical systems (MEMS) technology and precision engineering, the development of micro-assembly, micro-operation and other industries has been promoted, and at the same time, there is an urgent need for robots that can complete various micro-operation tasks such as micro-operation. In the precision micro-operation process, its key technologies are: (1) precision micro-positioning technology; (2) precision micro-operation technology; (3) modular design technology. Traditional micro-manipulation robots often have disadvantages such as bulky, mostly dependent on imports, high cost, poor versatility and portability, and poor environmental adaptability. In terms of precision micro-positioning technology, there are usually three positioning methods: 1. Macro motion driven by motor; 2. Micro motion driven by functional material; 3....
