This project uses easy to find and affordable components to construct a Pulse Width Modulation signal generator that can be used to test motors and servos. The ability to bench test motors, subsystems, or prototypes without the need for RoboRIO or special software can save time. It is also a fun and and interesting project for the electrical team!
A procedure for adding a hall-effect gear tooth sensor within the input stage of a VexPro VersaPlanetary gearbox. Requires modification of several inexpensive COTS parts; these modifications can be done by any moderately-capable FRC team in a reasonable amount of time and without use of external machining resources. This results in a robust encoder “stage” which performs comparably to a high-quality optical encoder, but for approximately 1/3 the cost.
