I am making a School Project. The goal is to build a vehicle. I have assembled everything as shown in the picture. It has a 40000 rpm motor, 12v dc battery, 6 inch lawn mower wheels for back. For the front wheels and steering - I made a small contraption using swivel wheels and pvc pipe. I connected the wires neatly, and put a start/stop switch. The motors are turning very fast, so are the wheels.
But the car isn't moving even an inch on the floor. When I lift the back wheels up, they are spinning very well and fast. Also if I push the vehicle manually without battery, it moves. So there is no friction issue. But when I turn on the battery, the car doesn't move. I tried on all surfaces - wooden floor, carpeted floor, stone floor. Still won't move. I also nudged it forwards, still won't move. What is that is preventing the wheels to not move, especially when the motor is spinning at 40000 rpm.
Someone suggested that I should get a gear system. But I get negative points if I put a gear system, as the car needs to be done under $200. Plus a gear system requires a lot of other work.
Any idea or help as to how to.make this vehicle move. I don't expect a fast car, but I want it to move with my current design. Much appreciated.
