Wheel
(diameter_mm, width_mm)¶ A base class for various types of wheels, tires, etc. All units are in mm.
One scenario where one of the child classes below would be used is when the user needs their robot to drive at a specific speed or drive for a specific distance. Both of those calculations require the circumference of the wheel of the robot.
Example:
from ev3dev2.wheel import EV3Tire tire = EV3Tire() # calculate the number of rotations needed to travel forward 500 mm rotations_for_500mm = 500 / tire.circumference_mm
