International ClassG05B 019/42AbstractA control system for a multi-motor system such as a space telerobot having a remote computational node and a local computational node inter-connected with one another by a high speed data link is described. A Universal Computer Control System (UCCS) for the telerobot motors is located at each node. Each node is provided with a multibus computer system which is characterized by a plurality of processors with all processors being connected to a common bus leading to a command processor. The command processor controls joint hardware and/or software for a plurality of direct current torque motors of the type used in telerobot joints and telerobot hand-held controllers. The motors are connected to the joint processor cards and respond to digital control signals from the joint command processor and a joint motor control card. Essential motor operating parameters are sensed by analog sensing circuits and the sensed analog signals are converted to digital signals which are stored at the controller card for processing by the command processor.The invention described herein was made in the performance of work under a NASA contract and is subject to the provisions of Public Law 96-517 (35 USC 202) in which the Contractor has elected not to retain title.Other References
