This thesis analyzes the supervisory control of the PUMA 700 series robot through a remote computer. Supervisory communication carries the control through MARK II controller, common controller for the PUMA robots, to a standard PC, enabling the development of purpose specific control programming without the knowledge of the VAL (Variable Assembly Language), robot-programming language. Using the supervisory communication feature of PUMA, new control software has been developed in which both VAL commands and interactive control commands can be executed simultaneously. The supervisory communication with the control software enables exploitation of third party applications and additional operating system features. The supervisory communication uses the Digital Data Communications Message Protocol (DDCMP). The frame structure of data messages, which is specific to PUMA robots, is fitted into this protocol. The messages embedded into DCMP are actually logical units, having different abilities and features. Data messages are formed with the interactive control software according to execution requests of the user. This thesis explains the implementation of the communication without using the CRC (Cyclic Redundancy Checking) on the remote computer side and the data messages formed with the interactive control software, which also enables the use of sensory inputs (camera, infrared, sound, color information) to be used for the robot motion control.
