Also, the chassis is not complete in the picture. We're still working on it now.

Why is the chassis cut on an angle at the ends? There are no obstacles to clear and I'd think you wouldn't want to be riding up over other robots.

Clearly you've never been pushed back far enough to be stuck on an edge of your frame and whatever else is lifting the other end of the robot. The cutback ends allow the wheels to be in contact at any angle. But, with mandatory bumpers now, that point is moot.

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.

I'm sure a team that's been around that long knows what CG is, and I bet that's only 50-60 pounds of what's going on the robot, you don't know how the rest is distributed. For all you know that could be all 1/16" wall and be much lighter than you are guessing.

114 of all people should know that being tall doesn't necessarily mean poor CG.

It looks to be 1/8th. However, I don't know for sure, which is why I asked the team if they had done CG calculations. And we very well know that being tall doesn't mean bad CG; our 07 bot was 11 feet tall, and could tip to 60 degrees and still stand up.


This drive base looks very solid. Think the poster could take a screenie with Inventor's CG icon in it, maybe a few views slapped into a post could really clear it up for all of us.

It is 1/16". That is 80/20 Quickframe (or similar); you can tell by the little black connectors in the corners. I have no idea what the structure is for, but it should be pretty darn light.

Thanks for the confidence, but no it is definitely not us.
Besides, when have you known the Pink Team to release genuine information about our robot before it is shipped? Never. Although, there may or may not be some revealing or pointless teasers coming some time in the near of distant future - so hang on to your seats.

What the heck is this...i am sry but did u guys think of the game or just did it...??? It is too top heavy.

Unless you weigh down the opposite side. Which you might not be able to weigh down enough if you can't make weight normally. If you can, pull a Quixilver and ziptie some rebar to your robot. It seemed to work alright for them...

REBAR!!!!

i dont think that cg would affect them in a normal game, going over the hump..... that changes things a lot.
