This simple project may seem to you a shivering robot but it is a good use of household things such as a paper cup, two AAA batteries, three felt pens, one small motor, switched battery holder and small metal weight.

Inspired by the idea of Portland team, Steve Lodefink managed to reproduce the wires, motor, switch and battery holder to craft the robot into a drawbot as the picture shows. When powered, the weight on the motor shaft will cause the whole thing to vibrate and toddle around the table.
