AN INDUSTRIAL ROBOT

摘要

An industrial robot having a trunk mounted for vertical and rotational movement on a stationary base is provided with two arm members extensible from the said trunk having a robot wrist mechanism attached to their ends. The extending and contracting movements of the arm members, rotational movement of the wrist and swinging movement of the wrist are controlled, respectively, by three electric servo motors mounted in a mounting compartment positioned on the side of the trunk opposite to the extensible arms.
