We use the vex ultrasound module and love it. It hooks up to the digital side car with two female to female pwm cable. This year we used it in our autonomous to guide the robot to the correct distance from the wall and shoot. We also use it to guide the driver when to shoot during teleop. Our main driver controls everything and one of the job of the co driver is to yell out the distance of the robot from the wall to indicate if the robot is in the shooting range.
We try to use the maxsonar and could not get consistent distance. It's also an analog device and we have to do some calculation to figure out the distance. Some people said you need a filter for an analog ultrasound sensor. Anyway it was frustrating using it and we have much better luck with the vex ultrasound sensor. The only thing is the vex ultrasound module does not like huge shocks to it. Because of the violent nature of our shooter we fried a total of three sensor from practice to the championship.
