"Distributed Digital Control of a Robot Arm"
by Gordon Wyeth, James Kennedy, and Jared Lillywhite
in the Proceedings of the Australian Conference on Robotics and Automation: ACRA 2000, pp. 217-222

Most robot arms use a central control box that contains the power electronics, the motor controllers and the coordinating computer. This paper presents a distributed control network that allows the power electronics and motor controllers to be placed adjacent to the motors. Each controller uses a DSP for all motor control, with the individual controllers communicating with each other and a host computer using a Controller Area Network (CAN). The design eliminates the bulky multi-core cable that is a major source of downtime for robots such as the PUMA 560, while improving controller bandwidth and facilitating greater software control of motor response.
