Hi all,
I am currently busy with my final year project for mechatronic engineering. I have to design a 50kg line following robot or AGV.
My mobile robot has to turn 90 degrees to turn left or right at variou junctions along its route. I have decided to use differential drive steering with two indpedent wheels and two casters.
I would like to use a microcontroller and control the motors with PWM via PID control. Should I use a stepper motor and precisely control the number of steps, or should I use a dc motor and encoder? Robot positioning has to be fairly accurate and I am budgeting about $300 dollars per motor and about $200 for a motor controller to interface with the microcontroller.
I am really struggling to get some technical answers for this, any adivce or links would be greatly appreciated.
