Industrial robot with drive devices mounted on high thermal conductivity structural parts, and method of manufacturing such robot

摘要

Manipulators of industrial robots comprise a number robot parts (10,20,30,40a,40b,50a,50b) movable one in relation to the other and driving means comprising an electrical motor (22) for moving the members. For controlling and supplying electrical power to the motors, drive devices (24,24',24'',31,32,33) are provided. The invention suggests to mount such drive devices to structural parts made of a material of higher thermal conductivity than that of other structural parts of the robot.
