A few kind of cool things with Xbox controllers and the rumble feature. One was my old team that I competed on in 2019. We had a “climber mode” where the operator could then go in and manually move the climber legs (there was no auto climb). To enter this mode, the operator had to press y so that they didn’t accidentally climb in the middle of the match. If they attempted to climb without being in climber mode, the controller would vibrate to remind them to enter climber mode. There was never a case when we didn’t climb for a lack of being in climber mode
The other examples are for my current team. We have a rollybeak style collector that when I pull in a hatch, it will vibrate when I’ve got a secure grip on it. This can help a lot in low visibility situations when other bots may be blocking my view of the HP station, and does a really nice job of reassuring me I have the hatch.
The final thing is for our climb. We have a suction climb, and when the pressure switch tells us that we have a secure seal on the platform, my controller will vibrate so I can tell the operator it’s time to climb. It’s just a nice little check that can help make sure we don’t climb before the robots ready.
I think that for teams that use Xbox controller in any capacity, the rumble is a really good feature that can help give the drive team cues about what’s happening with the robot without taking their eyes off the field to look at the dashboard.
