Wall Climbing Robot Live Hack....We Suck Again!

Sucky McSuckerton will live to suck another day! I now have a brand new 3.7V 600mAh LiPo which should sustain the load of 3 motors working at the same time. This RC wall-climbing car will be transformed into a wall climbing robot. Instead of using a third party H-bridge I think I'll try my hand at hacking the original circuit board. We may try to add a camera if it's not too heavy. If there's time we'll do some improvements to the 3D printed Rhinobot.

Lol at your title. I’m looking forward to seeing if the new battery fixed the glitchy servo issue. Be so sucky If it works!!

Haha yep! I actually found that when switched to a low voltage H-Bridge all the problems went away. I believe the issue is likely that the servo electronics can't run properly at such a low voltage (3.7V). Servos are usually only rated down to 4.8V, beneath that voltage is likely where mysterious things can happen. I might do some tests to verify this theory.
