wow, that looks pretty good. It seems that it might be too heavy though, are you planning on shedding any weight from it?

Looks good, did someone on your team do the wielding or was it sent to a shop to get done?

Looks really nice. I'm wondering about your weight though, the extruded aluminum is goin to get heavy, if you had gotten your gearbox welded, you should've gotten your chasis welded too or maybe used the kit chasis, was a lot lighter than our last year's robot chasis from extruded aluminum. But overall good job on your gearbox.

Extruded aluminum is actually relatively light. The stuff we are using is 5oz per foot for the 20x20mm and the 30x30 is 10oz per foot. So for our whole chassis that is around (This is just an estimate, I didnt actually do the math) ten pounds.
Anyway nice gearboxes. What reduction do they give you?

The material itself is light. All the connectors and bolts and T-nuts are not.

Good point. I will have to think about that for our arm design which currently calls for quite a few bits of various types of hardware.

and that looks beefy.

Our teacher welded the gearbox in our school (we are a technical school). We reduced the weight of this gearbox by shrinking down gears' hub and of course "speed holes".
