We got the smallest job-box that fit from radioshack and simply hot glued the sensor to back. Then we used a dremel to cut a circle in the cover of the job box.
The sensors were well protected. Our front one took a hit so hard that the job box broke off it's mountings and the sensor still worked fine, until I melted it trying to resolder a wire that I broke
.
Also remember to strain relieve your wires so no force is put on the solder connections.
On another note, was anyone who used the maxbotics able to improve their "slow" response and the initial overshoot they see when going from a short distance to a long one?
We wrote software that minimized the maximum amount the sensor could change in one loop to remove the overshoot, but there have to be better options.
In addition, the sensors couldn't respond quickly enough to give accurate readings at 15 feet per second. We had to set our front sensor to stop the robot at 48 inches. By the time the sensor saw 48 inches, our front end was about to contact the other robot.
