Hi, I’m trying to make the wheel go 20 feet but I don’t know how many turns the motor needs to go that distance can someone help me?
You have a couple of options:
- Move the robot a measured 20 feet and measure how many rotations the wheel makes
- This is the most direct, but least versatile method
- Move the robot a precise number of rotations and measure how far the robot moves, then do math
- This will give you a distance-per-rotation that you can use to move any arbitrary distance
- Calculate the distance the robot should move per rotation of the wheel (pi * {Wheel Diameter})
- This should give you the same distance-per-rotation number
From an engineering standpoint, I would recommend calculating and measuring the distance-per-rotation. This will allow you to validate your calculations (if they are different, figure out why they are different.
Good luck!
