DIY ‘encoder stage’ for VersaPlanetary
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.
