What are good motors for building a line following robot. I’m sure this question has been asked a thousand times, but I’m lost. I’m looking at building a RWD, twin motors (for propulsion and turning) and casters in the front. What type of motors will allow me to run approx. 1 foot per second. Oh yeah, using an Arduino.
Hello,
Your question is not as simple as you might think since it depends on the particulars of the robot you build. You can figure out the maximum speed of a given wheel and gearmotor pair by calculating the circumference of the wheel and multiplying by the RPM of the motor.
One foot per second is not too fast. As a reference, our 3pi robot travels nearly 3 times as fast using our 30:1 Micro Metal Gearmotor powered at about 9V with our 32×7mm Wheel Pair.
If you have not already chosen a driver for your line follower, you might consider one of our Arduino-compatible motor driver shields.
