What grade of aluminum did you use for the base, front, and rear sheets?

Pretty sure it's just 6061. Nothin fancy.

yeah, it's 6061, almost everything on the entire bot is 6061

How was that all cut out? Laser, water jet, or just a cnc mill?

All sheet metal was waterjet and all the box tubing was cnc mill.

Wow. I'm a bit surprised that 1/16" 6061 held up in such a high impact area. Especially with all that material cut out. Our drivers managed to bend a piece of 3/16" 6061 with a mild cheesing pattern in the same area this year. Glad that worked out for you guys though.

O, and your machines are always incredible works of engineering. I look forward to seeing them every year.

That makes sense. The side we damaged was the one side that didn't have a bumper (it would have interfered with ball pickup).

Yeah, the bumpers do make a huge difference in what you can put where and still keep it rigid.

We also had a small, probably....6-8inch gab in the front of our bumpers for our manipulator.

The bumpers definitely have a huge effect.

We ran the scrimmage in CT without bumpers and it left our robot with several dents and dings down the sides.

It ran around 12-12.5 ft/s.
