Re: What gyro and/or accelerometer do you use?

In the past, we have used the KOP one, and we have had trouble with it climbing. (It got pretty bad in some matches last year, climbing at a rate of over 1 rps). This year, we are using an arduino based one, the name escapes me.

A "fancy trick" we are doing this year is using vision to do a check on the gyro. The vision returns x y and z displacement as well as pitch roll and yaw. The yaw in vision is the same as the gyro reading that we care about, so every 2 seconds or so, we will set the gyro reading to what vision says it actually is.
