A Simple Way to Make Things Motorized

One fast and simple way to transmit power from a motor to a wheel or object is to move is to simply wrap duct tape (or even better, find a round peice of rubber that will fit around the end of the motor) around the moving part of the motor then attatch the motor to something near to the object that will be turned (such as a wheel) so that the moving end of the motor applies some pressure against the wheel (but don't make it apply to much pressure). Once your ready just turn on the motor and it should be working. This isn't nearly as effective as gears however, it provides a quick and cheap alternative.
