Wheels roll when picked up but wont move chip
Hello I just got my son a used chip robot his wheels roll but they will not move him I'm not sure if there is something I can do to fix that thank you
Some of the plastic gears in the wheels will be damaged (if you try turning the wheels by hand you will probably feel them grind and stick, they should move freely). It’s a complex job because you need to remove most of the internals to get to the legs, but then then you can inspect the gears that are damaged and replace them. Use silicone grease on the new gears to keep things moving freely.
