Introduction: How to Make a Simple 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:
1> An old PC's CD player's door opening mechanism.
2> Battery: 3.7V Li-Po battery (140mAh to 330mAh)
3> Two Green 3mm LEDs to make eyes.
4> One small switch.
5> Iron wires.
6> some pipes from old pen refill or sketch pens.
7> Wire, soldering iron, some tools like screw driven, cutter, pliers, glue etc.

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.
