This class uses a PID controller to control the wheel speeds of Bot'n Roll ONE A+
The minimum speed is about 250 mm/s and the max speed is 850 mm/s for a reference battery of 12V.
Note that these values might change depending on the battery you're using and its current charge.
You can specify your own PID params, kp, ki, kd.
This example uses the default values and an update period of 200ms.
Note if you change the update period you need to tune the PID params.
Important: Please run motors calibrate routine but instead of setting the power to when
the wheels start moving set it to when they stop moving.
This allows PID more room to control the speeds at lower values.
