Looking for a cheap but reliable IMU.
I'm looking for a cheap but reliable IMU for our demo bots. We have a couple of old chassis (just four drive motors and a control hub) that we use for outreach events. Right now they're driver oriented and we'd like to make them field oriented. The Control hub IMU is unreliable and we want to find something cheaper than a pinpoint or OTOS. Any suggestions on good IMU's in the $20-$30 price range?
