From what I can tell from the photo I would be worried that this design (as pictured) would violate <R19> (no wedge bots) thus making it illegal.

<R19> "Wedge” ROBOTS are not be permitted. ROBOTS shall be designed so that interaction with opposing ROBOTS results in pushing rather than tipping or lifting. Neither offensive nor defensive wedges are allowed. All parts of a ROBOT between 0 and 8.5 inches from the ground (the top of the BUMPER ZONE) that are used to push against or interact with an opposing ROBOT must be within 10 degrees of vertical. Devices deployed outside the ROBOT footprint should be designed to avoid wedging. If a mechanism or an appendage (e.g. a harvester for retrieving GAME PIECES) becomes a wedge that interferes with other ROBOTS, penalties, disabling, or disqualification can occur depending on the severity of the infraction.

Note that nowhere in the rule is there any mention of which way the wedge is oriented. Now your bumpers may fix the issue but since you are only required to have the bumpers on 2/3 of your robot it may or may not.
