Looking good Arefin! Lemme guess, battery will be in the rear? And possible 1/2 robot lift 12".

I'm calling arm on gearbox-side, ramp on the back.

[clean399]

seems like it will be a lifting robot not much ground clearance for going up ramps.

/me is scared

You guys haven't yet seen the pushing power of this beast... want to move the goal?

[sdcantrell56]

That's the first chassis that looks close to as overbuilt as ours. It's looking pretty good.

[David Guzman]

Looks good,

What material is the plate on the bottom.

You need to add some structure to resist that square from turning into a diamond. that piece of plastic all the electrical is mounted to isn’t offering any strength to the frame. also. bumpers are a must because there are moving parts exposed on the outside in the "bumper zone" that according to Murphy’s law will get smashed. as well as the front and rear being made of 1/8" thick c-channel offer little resistance to collapse upon impact. it would be a large benefit to add some central strength members to resist against that

That's not necessarily true. It depends what type of plastic it is and how it is attached under the frame. Which makes me wonder, how is it attached, and what type of plastic is it?

Nice setup. Looks like the top is exactly 4" of the ground. I wonder why?

you run any numbers on that? I'm not so confident on your structural collapse theory....

i didnt run numbers per say but i ran 179's 2004 robot at 12 feet/second into a mobile goal 10 seconds into it's existance and smashed the 1/8" c-channel in. bent! broken frame! misaligned wheels! it was a mess

[Conor Ryan]

Questions for the nicest looking chassis and drive train in awhile (I haven't seen Tytus's waterjetted one yet)

• How big are your drive sprockets coming out of the AM Shifters (not the ones built in, but the ones attached to the wheels)?
• Live or Dead Axles?
• Are your axles running on bushings or bearings?
• What is your base plate? Wood?

Keep up the great work 1345!

2007 + bumpers - mobile goal - full speed ramming = i do not believe this will collapse structurally, but i could be wrong i guess.....

So are the wheels near the battery powered at all? Interesting placement of your gearboxes there. I want to see some video of this in action asap Arefin
