I have a problem with my Bittle. Everything through assembly and calibration went perfectly however after installing OpenCat.ino the only response it seems to give is a weird twitch where it lifts one leg and then pulses. It won't walk or leave this position. When lifting, it moves legs as if to balance. I have tried communicating through bluetooth, the Serial Monitor, and with the IR remote. All are the same. Using the IR remote test sketch the buttons seem to come through fine. Any ideas?
