Here I wanted to present a draft of the vehicle robot. The heart of the robot is the microcontroller ATtiny2313. Drive the robot are the 2 stepper motors. The inspiration for the construction of my robot were other projects. In most cases, these are projects based on the Arduino and servo-motors. In my case I did not use the Arduino platform. Software for my Attiny prepared in C. As previously mentioned, I used instead of servo motors stepper motors. It’s powerful precision robot control. Stepper motors work here independent what allows twisting right and left. However, the disadvantage of using stepper motor is the low rotational speed which translates into a speed of the robot. As you can see in the video, my robot is not too fast ;-) Additional stepper motors which I used have a internal gears. However, as regards the precision of control I’m very pleased.”
