hope im posting in the right place. i have a project turning a robot that walks, into one that uses wheels, i need a part that will turn the leg motors that go back and forth into ones that go in one direction constantly. i cant make them go in one diirection by themselves, its complicated. is there a part/component that will do this? i seem to remember the name of somthing but its slipped my mind. if you need further explanation, just say so. any help finding the part i need is greatly appreciated:smile:
