When I run a programm on the Allbot with the USB cable connected to the PC, it works ok. When I disconnect the USB cable, the Allbot starts behaving differently. The servos start moving in small steps. When I connect the USB cable again, the program works ok.
Of course, the batteries where switched on all the time.
This is similar as the topic “ALLBOT strange servo behaviour”
Problem solved: I had used rechargeble batteries, which had less then 5 V. Using fresh alkaline batteries solved the problem
