I have followed instructions, both via Youtube and documentation, I am 100% sure that I have everything assembled correctly. I have checked that the switch is turned to Arduino, the battery is fully charged. I have uploaded the WriteInstinct and run the sensor initialization, and after that, I tried to do the calibration, however, whatever button I press, Bittle just jerks motors slightly and nothing else. According to the docs, it should at least try to walk or move motors a bit more, but I think that in my case something is wrong. I am not sure how to proceed, so any suggestion is more than welcomed.
