What steps must be taken to reverse a robot's direction?

To reverse a robot's direction, setting the motor power levels to negative numbers is necessary. When motors are driven by negative power values, they rotate in the opposite direction compared to when they are powered by positive values. In many robotic systems, including the VEX Robotics platform, the direction of rotation for the wheels can be controlled by adjusting the power levels applied to the motors. Negative values typically result in backward movement.

While there are other factors that can affect a robot’s direction, such as wheel configuration or mechanical components, the immediate method to reverse movement is through the power levels. Setting motor power levels to zero would halt the robot, and configuring wheel direction might be part of a different, more permanent adjustment but does not directly reverse motion instantly. Therefore, using negative motor power levels is the most direct and effective way to achieve immediate reversal of a robot's direction.
