# Robots using modular direct drive motors

## Abstract

A direct drive robot motor may be used for the arms, legs, eyes and fingers of a robot. The motor comprises a rotor, having a permanent magnet, and a tubular arm portion, which is integral with the rotor and extends outwardly through a slot in a stator body. The stator body is wound with an aluminum coil and has a tubular extension to link it with the arm of another direct drive motor.
