I'm building the cat with my son as a father/son project and we're so close to finishing, but can't figure out the cable connections. I can't make heads or tails of attaching the wiring for the head or tail (or legs). I see lots of diagrams on the help forum that I can't understand. Is there a photo or diagram that says, "these prongs are where you attach the head" and "these prongs are where the left rear leg attaches"?

With writeinstinct.ino sketch loaded I calibrated joints, updated instincts, and calibrated the MPU6050 with no problems. When entering commands into the serial monitor all positions work and run great; sit, walk, rest and kbalance stands level with head and tail straight. The problem accrues after loading the main Nybble.ino sketch. Nybble works great with the remote control but on the balance command the body of Nybble leans to the right, the tail moves to the right of center and the head tilts down and to the right. The walking goes to the right quite a bit when testing with writeinstinct.ino loaded. The other positions look "true" when sitting, pushups, rest, butt up etc.. Also with Nybble in balance/standing position when pushing and or tilting Nybble to the right or left the right side goes over very easily while the left side has a more notable resistance when pushing over. It falls/leans easier to the right side and never will fall over to the left side. Front and back tilt work good with legs moving into the underbody position. No amount of calibrating the MPU6050 or servo angle adjustment has corrected this behavior. I have calibrated more than several times, even switched servos leg assemblies, looking for a really weak servo(s), to the other side but with no better results. I noticed when running the calibration for the MPU6050 in the serial monitor waiting for the "6 numbers", it has more than once brought up only 5 lines of numbers on the completed MPU test and the test at times took over 25 lines of numbers printed out in the serial monitor before the MPU testing was finished. ( lines of numbers like this; " -1390 2206 999 100 -8 8 " ) Is it possible that the MPU6050 gyro/accelerometer is failing ?? The NyBoard Version is V0_1 mounted servo wires side down with the FTDI connector to the rear of the cat and have been using 2 sets of EBL 14500 fully charge batteries. I have not modified the NyBoard to "Pro Version" as like on the forums. So far its been fun, Thank You for the great kit Rongzhong & Team Members! Any help would be greatly appreciated !
