Adaptive cruise control for TI-Rover uses a 4-state state-machine model to keep Rover within a defined distance from an object (a moving block, a wall, another Rover) - state 0: object too far (or no object detected). RGB LED is red. Rover does not move. - state 1: object within range. RGB LED is green. Rover does not move. - state 2: object beyond range. RGB LED is yellow. Rover moves closer to object (forward). - state 3: object too close. RGB LED is yellow. Rover moves away from object (backwards).
