I just went to mount the parallax ping sensor using the mounting bracket with servo and it fits perfectly on the front of the rover. The only issue is balance. Even with the batteries take out I am going to have to put a counterweight on the back. A picture is attached.

Actually I haven’t quite solved this yet. I removed the batteries in the front to lighten it. I tried a piece of aluminum bar on the back but that wasn’t really heavy enough. I am going to try and find a nice hefty bolt to strap to the back. Need steel or iron because that parallax rig makes it really front heavy.
Actually one other thing I am dealing with is cable management for the external sensors. I built the adafruit “screwshield” but it is too long and hits the bluetooth socket. I am going to try the original wingshield to get around this. It would be nice if this board was redesigned with the ability to use either screw connectors along the sides but still be able to accept normal shields stacked on top.
Hi johnelle,
We certainly appreciate the photos and look forward to seeing what you have planned for your rover. As you pointed out, the DFRobotShop Rover is very lightweight, so the approach of adding counterweight (especially in the form of batteries) seems to be the best solution.
Sincerely,
Instead of using a “dead weight” at the rear, consider strapping a 4xAA battery holder (cube) or 6Ah LiPo battery. Yo may also want to move the servo to the prototyping area and stick it to the top using double-sided tape. The universal mount was designed more for the MPSH-01 sensor mount:
