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.
1. Preparation components
2. PCB
3. Programming the microcontroller
4. Soldering the components
5. Mount vibrators and stands
6. Draw a course
7. How to run and test
* HEX and PCB and Source CODE files attached.

Soldering All Components
Mount the Vibrators and Stands and Battery:
Cut 3 Needle for Robot Stands (left & Right= 12mm Front=13mm)
At Over of a Soft Surface Draw a Course With 6mm Width:
How to Run and Test:
NOTE:
1.The Robo_ RIZEH full paper article published in ADVANCED ROBOTICS journal:
“Design and motion analysis of vibration-driven small robot Rizeh”
2.Robo_RIZEH get first place at RoboCup IRANOPEN2013 in Demo league (free style league)
3.Special thanks to Prof. Adel Akbarimajd my partner in this project.
