ABSTRACT:
A joint type robot comprises a fixed bed, a swivel base on the fixed bed, a motor base on the swivel base, an upper arm capable of elevating on the motor base, a front arm capable of elevating at the tip of the upper arm, a wrist at the tip of the front arm, and so forth. The upper arm extends rearward beyond the center axis of rotation of its elevating motion. The rearwardly extending portion can enter a notch of the motor base. A driving motor for turning the swivel base is disposed at a position deviated from the center axis of rotation and in parallel with the center axis of rotation. The pair of driving motors for the upper and front arms are mounted on the motor base parallel to each other yet oriented in opposite directions to keep the robot as small as possible. The wrist driving motors are mounted on the upper arm in similar fashion. All the features of the robot are designed to keep the robot as small and as light as possible.
