What happens if the popsicle stick is perfectly centered? What happens when it is way off-center? Move on to the Materials section to see the list of supplies you will need to build your own Art Bot, and the Procedure for instructions on how to build one and do the experiment. In this science project, you will find out how the weight attached to the motor affects the robot's movement. Your Art Bot will also have markers for "legs," so it will draw on paper as it moves. This is the same technology that makes video game controllers and cell phones vibrate on the inside, they have little spinning motors with weights attached. When the motor vibrates, it causes the robot to wobble across the paper. The motor has an off-center weight attached to it (the popsicle stick in Figure 1), which causes the motor to vibrate. When you connect the battery to the motor, you complete an electrical circuit, and this allows the motor to spin. In order to power the motor, the robot also needs a battery. The Art Bot uses a small electric motor to move.
