Today Saurav Chakraborty over at instructables shows us a quick and simple guide to build your very own two legged walking robot. One of the most difficult robot is two legged walking robot. Its balancing mechanism needs a complex circuit , lots of sensors, gyro, servos and mechanics. All the parts are controlled by microprocessors with complicated Firmware. But here we have made a very simple two legged walking robot for kids. To drive the legs we have used old CD player’s door opening mechanism. Mechanical structures were made from iron wires.

Step 1: Components/Part Necessary:

Step 2: Step-by-Step Video Instruction:

Step 3: Some Necessary Information:

Step 4: Schematic

The circuit was powered by a small 3.7V Li-Po Battery. Two green 3mm LEDs in series with 330Ohm resistors were used to make eyes.
