Sensors for mecanum wheels?

I guess you wouldn't be using a hard drive in your DS?

Nah, SSD.

Though I think if you have to evacuate all metal in a 5' radius, no electronics are safe...

We are using Java on our robot. I ended up not using a generic method/class used for mecanum drive but instead made a class from scratch, which ended up working. And thank you to who said "Fieldcentric control" that was what I was thinking of! What gyro sensor should we buy to use with our robot?

I coded a field-centric mecanum drive last year, and the kit gyro seemed to work fine. After ~10 minutes of driving there was no noticeable drift. I suppose that you could always purchase a higher-precision gyro, but my opinion is that this is unnecessary.

We did not incorporate the accelerometer, and the code still functioned well. So I would say to not worry about that. As stated above, make sure to zero the gyro as soon as the robot enables.

Gyro only. We started using field oriented drive back in 2010, here's a video of it in action. I would also encourage an encoder on each wheel if you haven't already done so, so you can stop as much drift as possible.

What sensors and encoders did you use specifically?
