Motors aren't strong enough

Hi Pololu engineers! I bought a Zumo Robot for Arduino, so I assembled it, but then I tried testing it by turning on and turning off the motors in a simple arduino program and when i put it on the floor it was as if the Micro Metal Gearmotors didn’t were strong enough to move the zumo, i whant to know if i could have made a mistake in the assembly or my motors aren’t working, or if it could be the program. Thanks!


I am sorry you are having issues getting your Zumo running. Are you using gearmotors from us? If so, what are the product numbers? If not, can you link to the product page for the gearmotors that you installed in your Zumo?" Are you using fresh or fully-charged batteries? Also, can you post the entire sketch you are running?
