I recently ordered two six robots and some extra servos and some sensors from brookstone. I have a defective camera....I followed the advice here and confirmed bad camera after swapping in the other. Also reseated connectors and both circuit boards in bad camera, no help. I also have three bad lever servos...they just dont respond at all. I also had a bad ultrasound sensor but replaced the HC-SR04 inside and it seems ok now:) Can I have the three servos and camera replaced?
