When tracking curved lines, how should the motor power levels be set?

When tracking curved lines, it is important to adjust the motor power levels for each wheel to enable the robot to navigate smoothly and successfully follow the curve. Setting the motor power levels far apart allows the robot to turn more sharply, which is often necessary on a curved path. This adjustment helps to facilitate the difference in distance traveled by the inside wheel compared to the outside wheel on a curve.

If both wheels were set to the same power levels, the robot would have difficulty maneuvering around curves and may veer off the intended path. Conversely, having the motors opposite in power could result in erratic movement or turning too sharply, leading to loss of control. Matching the straight line power levels would not consider the dynamics of navigating a curve, as the required turning force and traction would differ from traveling in a straight line.

Thus, setting the motor power levels far apart ensures that the robot can effectively follow the curvature of the line while maintaining balance and control.
