First of all I would like to thank all the forumers for being very helpfull. I have started with this robotic hobby a year ago and this is the result. It's not really big deal for you guys with lot of experience but at least something for me with zero knowledge in robotics.
This is a simple autonomous·robot that use Toy Tank for the base. I used 2 HB25 for the motor controler and Ping·sensor. In future I will add IR sensor for edge detector.
Any idea and proposal to improve this robot are welcome.
Thanks to·Parallax for their great support.
Sorry for my not so good English.
