We on 1519 have used the navX-MXP for determination of heading and tilt on our robot every year since 2015, with excellent success. The navX was a key enabler for heading-maintenance on our 2015 mecanum drive robot, in 2016 going straight over defense both in autonomous and teleop, in 2017 for driving straight with our H-drive robot, in 2018 for accurately driving long distances on a specified heading in autonomous as well as controlling our upper assembly turret in field-oriented control, and in 2019 for providing heading updates for closed-loop heading control for placing hatch panels on the rocket and cargo ship. In all these situations, it just works. From our perspective, the functionality should have been in the roboRIO to begin with -- Kauai Labs made a great product, and AndyMark simplifies procurement for us. Thanks so much!
