Team 4004 (MARS Rovers) has developed a handheld PWM generator that allows a user to quickly and easily connect to a speed controller (Jaguar or Victor) and run a motor. We developed a basic version during our rookie year while our programming team was busy trying to figure out the cRIO.
We've now repackaged the unit into a nice handheld device that makes it very easy for tems to run a motor during testing and prototyping of robot designs. It also comes in handy during troubleshooting if you're just trying to run a single motor on your robot.
AndyMark has two sample units at IRI and is considering offering them for purchase through their website. If you're at IRI, check them out. They will also be available for purchase at the team site soon.
