Abstract: A system for welding together tips of different wires arranged about a motor stator. A scanner control module is configured to operate a three-dimensional scanner to scan the tips of the different wires and measure alignment of the tips in X, Y, and Z directions of a coordinate plane. A system control module is configured to compare the measured alignment of the tips to a predetermined alignment range, and configured to identify a weld schedule for each of the tips that fall within the predetermined alignment range. A laser welder control module is configured to operate a laser welder to weld together only the tips aligned within the predetermined alignment range in accordance with the weld schedule identified by the system control module.

Abstract: A control system includes: a command module configured to generate first linear and angular velocity commands for a follower autonomous mobile robot (AMR); an error module configured to: generate a first error for the follower AMR between the first linear velocity command and a present velocity of the follower AMR; and generate a second error for the follower AMR between the first angular velocity command and a present angular velocity of the follower AMR; a proportional integral (PI) module configured to: generate a second linear velocity command for the follower AMR based on the first error using PI control; and generate a second angular velocity command for the follower AMR based on the second error using PI control; and a driver module configured to apply power to one or more electric motors of the follower AMR based on the second linear velocity command and the second angular velocity command.
