If I select rest on the remote or d by serial my Nybble crouches down and turns off the servos. Yet if I pick it up and turn it over to disconnect the battery it does what I assume is an attempt at self righting, turtle roll. It returns repeated k in the serial communication while doing this. Should it remain still when in rest (or d)? I get the same motion if I flip the cat over in other functions, but it does not self right. Is the self righting set up for the dog and not the cat? The video on youtube of the cat self righting has the cat's head rotating to get it over, mine just flails it's legs in vain. I do not have the rubber feet as I broke all 5 trying to install. The FTDI board initially would not download any sketch, always had a communication error. It would however read the serial port. There was a solder bridge connecting rx and tx at the pins.
