Setting up the SumoBot Competition Ring Poster
The SumoBot robot and SumoBot Robot Competition Ring poster are for indoor use
only. For best results, follow these setup instructions:
Initial Adjustments
The plow is held to the chassis by two screws shown in Figure 1-2. Each screw passes
through a slot in the plow. Adjusting the plow is a simple matter of loosening the two
screws, changing the plow's position, then retightening the screws. Each slot only has a
few millimeters of wiggle room. Even so, the slight adjustments you can make to the
plow’s height and tilt can make a big difference in performance.

Unfold the SumoBot Competition Ring poster, and re-fold it the opposite way so
the creases will lie flat, then unfold it again.
Find a location with these characteristics:
Place the ring on this surface, and secure the corners and edges with clear tape to
make it lie flat.
If, from frequent folding and unfolding, the creases start to appear white, touch
them up with a black felt-tip marker.
If possible, place some heavy books on top of the creases for a couple of days to
flatten them out.
Start by adjusting each plow so that it is flush to the sumo ring's surface along its
whole length, as shown in Figure 1-2.
