The Wooden Duck (Voice Command)

These are blue prints for the famous wooden duck from Lego. I have convert the duck in to a voice command. So it can move forward and backwards and side to side. This is a unique piece ,you can see on the blueprints that it has the 9V engine and 9V motor to control the ducks movement forward and backwards and it turns, the tricky part was keeping it compact hope you like it.
