    摘要: A method of and apparatus for achieving dynamic robot accuracy includes a control system utilizing a dual position loop control. An outer position loop uses secondary encoders on the output side of the gear train of a robot joint axis, while the inner position loop uses the primary encoder attached to the motor. Both single and dual loop control can be used on the same robot and tooling axes.

    摘要: A synchronous high speed motion stop for a series of multi-top loaders residing on “n” controllers on one rail achieves effective detection of the servo-error status and shut off of the trailing controller's servo power within 3 ITP time. The control method reduces the unnecessary error recovery because it only shuts off its immediate trailing controller without aborting its leading controller, allowing the leading controller to complete the cycle tasks. The cascade control method produces a synchronous high-speed motion stop for the robots across the controllers and effectively prevents the collision between the robots.

    摘要: A system and method for controlling avoiding collisions and deadlocks in a workcell containing multiple robots automatically determines the potential deadlock conditions and identifies a way to avoid these conditions. Deadlock conditions are eliminated by determining the deadlock-free motion statements prior to execution of the motions that have potential deadlock conditions. This determination of deadlock-free motion statements can be done offline, outside normal execution, or it can be done during normal production execution. If there is sufficient CPU processing time available, the determination during normal production execution provides the most flexibility to respond to dynamic conditions such as changes in I/O timing or the timing of external events or sequences. For minimal CPU impact the determination is done offline where many permutations of programming sequences can be analyzed and an optimized sequence of execution may be found.
