With the additional current drawn by Pi, Nybble will be less capable for intense movements, such as trot (the token is
ktr). The system is currently powered by two 14500 batteries in series. You may come up with better powering solutions, such as using high drain 7.4 Lipo batteries, or 2S-18650. There are a bunch of considerations to collaborate software and hardware for balanced performance. With Nybble's tiny body, it's better to serve as a platform for initiating the communication framework and behavior tree rather than a racing beast.
