The Ultrasonic Scanner package is a highly recommended addition to the SuperDroid Trekker or your own personal robot project.� The sweeping Ultrasonic detector is a Devantech SRF04 Ultrasonic ranger mounted to a servo that mounts to the front of the Trekker chassis with the front scanner bracket.�It can also be mounted to the top of the Trekker chassis with the single or dual top scanner bracket.� The servo can be programmed to scan at any angle from -90 to +90 degrees (0 degrees being straight forward).� This gives the Trekker (or your own robot) a set of eyes.� The Ultrasonic detector will detect obstacle and cause the robot to stop, the servo can then look in either direction for a preferred way around the obstacle.�
