Go to Post I am surprised at the relative conservative capability you described on our 2006 machine. As for the 2007 machine, in anticipation of an aquatic game, we have completed a robot that "walks on water" and are well along with one that can "part the sea". - Bill Beatty [more]

Bumpers must be constructed as follows (see Figure 4‑4):
be backed by ¾ in. (nominal) thick by 5 in. tall plywood.
hard Bumper parts (e.g. plywood, fasteners, etc) may not extend more than 1 in. beyond the end of the Frame Perimeter(see Figure 4‑4).

James, hank you for helping. I believe we looked at the pictures wrong when we designed our bumpers. We need to shorten the front bumpers so they only overlap the plywood backing of the side bumpers. Thank you again for drawing our attention to the issue!

Ross, the robot is not perfectly built. The frame is parallel, but the inside beams distort slightly downward. We built the front "arch" to force the frame back into shape, but it still says a little. We are continually monitoring the situation, but the problem seems to be purely aesthetical at the moment.
