FRC2046 2012 - Bearmageddon

[Darren Collins]

Here is a picture and a render of Bear Metal's 2012 practice robot which is functionally the same as our competition robot. I admit that parts of our bot are a little crazy, but our 12 designers had a lot of fun keeping our fabricators busy.

We are excited to be attending both the Autodesk Oregon Regional and the Seattle Cascade Regional.

A few details:

4 Cim drive through a single speed custom gearbox using AM gears for a 8:1 gear ratio

Skid steering with ten 4" AM performance wheels which are cantilevered. This sounds superfluous, but we decided to use small wheels to maximize our wheel base since we're driving wide.

A pneumatic "multi-tool" aids in traversing the barrier and manipulating the ramp up and down. It also fits nicely uner the ramp, stabalizing it to expedite the balancing of our two allies.

It has a turret combined with a wheeled shooter which shoots at a fixed angle.

Two vertically mounted pneumatic cylinders in the back aid in a three robot balance scenario.

Have you tried your multi-tool on a bridge that works to FIRST specs, or just the practice bridge? There's been a lot of week 1 teams surprised by how much harder it is to flip the real bridges. If you've only tried the practice bridge you might want to bring a pair of beefier cylinders to your first competition, just in case.

Unfortunately we have only tried it on a practice bridge. I'm fairly confident that we can push down a competition bridge but not lift it to clear balls under it or operate it for our alliance partners to enter from the other side. Fortunately we have found the weight reduction to fit cylnders that increase our force by about 50% and may have the weight to fit cylinders that double its force. We do plan on attempting to obtain said cylinders before we leave for the Autodesk Oregon Regional on Wed.

Very cool, I like the CNC mill work on your aluminum. I am looking forward to seeing you in Portland and seeing the your multi-tool in action!!!!
