Large amounts of gyro drift

[Joe Johnson]

I have no financial interest in AndyMark or Kauai Labs but we are using the navX MXP Robotics Navigation Sensor and we LOVE it.

I was a complete skeptic when the coding team insisted that we could do Field Centric driving using our Wild Swerve modules. But after looking into it, asking a real roboticist that I am lucky enough to work with, and, most importantly, after seeing it work on Rover (Overclocked's fall "Practice Project"), I am a complete and total fanboy.

The navX MXP is amazing. If you are not using it, you should be.

It takes the literal "rocket science" technology from InvenSence IMU and puts it in an beautiful and well behaved (and Open Source/Open Hardware) wrapper.

IT IS AMAZING.

If you are using a gyro and you're not using a navX, I think you're missing the boat.

Free advice, worth every penny.

P.S. They claim 1 degree per minute drift. Again, I was skeptical but I think actually, in most cases, they do better than that. We will often practice for 20 minutes and stop because the motors are hot or the battery is dead not because we need to rezero the gyro. YMMV but that is our experience.
