• Actuators / output devices: one servo
• Control method: autonomous
• CPU: Bicore
• Power source: 6v 1600mAh Ni-MH
• Target environment: Indoot

Well this is my first successful robot, it my version from the one motor walker developed by Robomaniac, you can find a great tutorial here http://www.instructables.com/id/How-to-build-the-one-motor-walker/

I used this servo from Hobby king http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=16269 they are very strong and cost only 3USD and give up to 4kg torque

I made only slight mechanical changes on it, instead of using the gear I used a crossed bar, and the legs are made of a rod I use in air-modelling it is strong and light but is not too easy to form. That is why the legs are not perfectly symmetrical but I think this give the bot a fumy walking style

I also added a loose feed back pin that make the walking patterns to change from time to time, which I really like :D look more organic to me :D if falls down in the second video

I also added a pair of blinking LEDs to make it look more insect like

Finally I used 4 Ni-MH batteries instead of the alkaline ones and I am simply using a plug instead of a switch
