Hi - you need to use an off-center weight to make the robot vibrate and move around. Since the propellers are symmetric, they will not make the robot vibrate, and they will probably not be powerful enough to push a heavy robot. You can build a smaller car with a propeller mounted in a motor, as shown in this project: https://www.sciencebuddies.org/stem-act ... peller-car
