#1 Wheel rocker V01 by Catalin
This is a design based on a small electric motor powered by a 9V battery and a switch that reverse the motor rotation. Is simple, cheap and functional. Between the motor and the wheel for low current consumption and a soft movement there is a gearbox based on an RC reductor. on the wheel there is a pin that after a full rotation hits the switch button changing the electric motor polarization reversing the rotation of the wheel.
