BaneBots new product. (read AM)


Very nice stuff Pinecone (Idc how much I like your team, I still get to make fun of you!)

Oh my bad my bad. Mixed up the name with the CIMple Box from AM

Actually, nope. Banebots is making it. Check their website.

I wish it were an AM product though

Nice use of Inventor!!

You can view some preliminary pictures with electronics here.

We are planning on using Anderson connectors to enable us to put the Victors much closer together than otherwise possible. Wire paths have yet to be drawn out.

A) Are you planning on running the chain on the inside of the frame?
B) Are the bumpers going to be mounted right onto the standoff blocks, without any other support?

Yes and Yes.

The spacing between the edge of one stand off and the edge of the next closest stand off is always less then 8". Which is to say that the center points on the standoffs may be a bit more then 8, but if I am reading the rules correct "and no section of BUMPER greater than 8” may be unsupported)" just having material behind it suffices. And with a bolt holding it in place, and a generous amount of stand off to support the bumper from twisting, they should be good.

Nice work.

Something to consider. It looks like very little ground clearance.

If you have anything stick through the bottom plate, it could rub the carpet.

And, there is a small step in the carpet around the towers. There is a plate under the tower base, and then a layer of carpet covering it.

Looks great. I love the belt running through the tube. Very slick.

I would actually say that is my least favourite feature about this chassis.
it's cool no doubt, but looks like a pain to maintain if you throw a chain...

A lesson I learned from my mentor a while back was to design for maintainability, as well as performance and looks.

It took about 7 minutes to change a belt on our prototype chassis.

This one will have a removable easy access window over the middle wheel. That and practice / belt changing drills should bring it down to 5 minutes - twice as fast as our previous dead axle drivetrain.

We also stress tested the drive. Stalled the wheels multiple times, ran it forward and back a bit with no signs of slipping or failing.

Looking at the CAD with electronics, I just wanted to point out that the only legal bridge this year is the DAP-1522 included in the kit.
Looks like a pretty cool drive design with the 6 motors

[Matt H.]

Why did you choose to use six motors in your drive train?

4 CIMs at a 7.4:1 ratio gives a maximum of 634 in-lbs of torque at the wheels. With 4 inch wheels, that becomes ~315 lbs of force to accelerate the robot. However, with a generous coefficient of friction of 1.5 your robot will spin its wheels at 180 lbs of accelerating force.
