![]() In this situation Error = speed_Master - speed_Slave However, as expected, the bot cannot travel in straight line.Ĭoncept: Keep it simple by having one motor serve as the speed master and the other as a speed slave, where the master motor speed is held constant and the slave motor speed is varied so as to match the master motor speed. Great precision is not needed for this challenge therefore, limited tracking (drift) back and forth across the straight line path is acceptable.Ĭurrent situation: The bot has been tested and it goes forward, backwards, turns etc. Hobbyist Situation: Good hardware/electronics skills, just learning how to program.Ĭhallenge: Creating a sketch that will allow the bot to travel in a straight line for some distance, turnaround and travel back to the start point. Project: Arduino robot with motors equipped with hall effect quadrature encoders.
