The autonomous robot that follows the line with the highest speed.
The vehicle was created on a PCB and contains electronic components like motors, sensors, leds, buttons, voltage stabilizer, battery and microcontroller ATMega16A. Photointerrupter sensors detect board color and provide data to microcontroller. Position offset is calculated and there is also implemented PD controller that is responsible for correct movement.
Robot has to move precise, don't lose the path and be quick at the same time. Board and line have opposite colors. Track can be right angle and with a crossroads.
Presented robot participated in few tournaments. One of them you can watch here.
