Thanx very much..

Thanx again!! Nyb is working. It crawls well, though it has trouble walking. It squirms when I pick it up. ( Maybe I can add a scruff switch ? -put it to rest when I grab it by the spine ;-) ) Is there a way to re-calibrate the MPU6050 while running Nybble ? I know I can calibrate the servos via the IDE. For some reason the tail was out of calibration. Oh those servos seem pretty strong. Not sure what commnand I gave it but Nyb almost shot itself off the table. Have to ask what is "Recover" supposed to do ? And thanx again for your help earlier.

Thanx I wondered if I'd missed an upload. I had help from my "daughter" with the software yesterday that enabled me to get this far.

EBL 14500 - 800 mAh. These fit the holder perfectly. Now if I can just figure out the Arduino IDE....
