The word "Rizeh" is a Persian word that means "tiny". Rizeh is a vibration based very small robot. It is driven by two vibrators of cell phones. This makes the robot very low cost to build and implement. The robot is able to perform linear and circular motions as two basic motions in mobile robots. Control mechanism of the robot employs internal PWM of micro-controller to control vibrators. Some techniques are applied to minimize electronic control board of the robot which is a very crucial in building up a small robot. As a standard task in mobile robots, line following task is selected to test Rizeh.

Hi
Nice Job !

I built myself a little robot with 2 wheels and 2 micromotors
1 IR sensor IS471F
the whole is controlled by a release ATtiny13 SOIC
and is programmed in BASCOM April
Build micro robots is very interresting

Oh, my stars, that is both awesome and very cute.

I particularly like the way you use vibrating motors instead of wheels.
