Hello. I am enjoying assembling this robot cat ,Nybble .
But I can't finish setup.
I can't finish calibration. I tried calibration more than ten times.
But I can't finish because the cat move abnormally.
After I typed 'c', all servos were moving and stopped.
After stopping I tried to calibrate and joined leg parts.
And I calibrate each of servos, the 10th servo, the 9th servo, the11 servo, the8 servo, and the cat abnormally .In that case I can't stop it. Several of servos moved abnormally.
After that I unplugged USB cable from uploader. And I reconnected USB cable.
But the cat move abnormally again. So I have no choice but to reset the cat.
Is this cause battery trouble? USB cable trouble? and other?
Could you tell me the why?
The first half of the video shows the situation before and after the start of calibration. The second half of the video is an operation check after writing Nybble.ino. At the end of the video, Nybble tries to walk with knees and elbows.
