Cannot believe this was allowed to compete after 118 was denied.
It's not probable, but it is possible that their CoG is indeed over the bridge surface. Just from looking at this picture, it seems like they have a relatively small superstructure, which could free up weight to use as ballast towards the bridge side. However, I have no idea if this is actually the case. If someone from this team or someone who is familiar with this robot could clear this up, that would be wonderful.

EDIT: From this image, it appears that the side over the bridge is considerably more dense than the other side, including solid aluminum (steel?) blocks being used as ballast, so the possibility of an extremely biased CoG is possible. However, it also appears that there is a metal piece under the robot touching the side of the bridge. I can't tell if it's just used for allignment or if it reacts against the bridge.
