Problem with motors on brand new mBot Ranger


My son and I just opened a brand new mBot Ranger 3-in-1 Educational Robot Kit. We built the mBot in the Land Raider configuration. Everything went together fine. We loaded the mBot app on my android phone and tried to drive the robot. The problem is that we hear the motors spinning, but the output shafts only moved a little and then stopped move completely. Almost as if the gears in the motor housing are stripped. Any ideas?


May I know which kind of battery do you use? According to our test and research, it is suggested to use Alkaline battery with good quality like Energizer, DURACELL or rechargeable nickel-metal hydride or nickel-cadmium which can be bought from amazon or local shop.
