7068 T6 Aluminum.

I'd say that they are gearshafts. Maybe output shafts.

Unobtanium?

no, unobtanium has infinite strength and is massless, and therefore would be 0% the weight of the aluminum. I'm going to say maybe titanium as an offhand guess since i haven't crunched the numbers

a very heavy snowflake...

What I'm interested in is that the layout of the parts in the photos being presented is very done well. The photos themselves - separately and together would make an intense, dramatic, and beautiful display.

good stuff...

To add: these would also make great jigsaw puzzles and cards.

This is the closest guess so far. Not an output shaft though.

The black material is not polycarb. Keep guessing. They use the same stuff in a lot of paintball parts.

I was hoping to post up another picture tonight, but I've got to wait for the correct answer! So hurry!

I agree. The only thing I can think of that has similar numbers is Grade 9 titanium and that stuff is beastly expensive.

A quick look a McMaster-Carr confirms that it has the tensile strength of 7068 and aluminum alloys are also about 1/3 the weight of steel. Anyways, the strength and weight are way off for it to be titanium. They are very, very nice shafts.

i think everyone is missing the big clue. There are 16 of these "axles". That is a large number. Just like the large number of "wheels" in the last post.

My prediction;

The Robotic Alliance of West Covina has been expanded to include more teams.

Keep in mind that 16 also equals 8*2. So, it is fully possible there is only one team in the RAWC and they are building a competition and practice robot both with 8WD versions of the West Coast Drive. (Which would be really awesome if that was the case)

they are explained this....2 teams, 2 robots each, two demo gearboxes, please refer to the previous thread they had on their unfinished parts

The material is 7068 T6. It is really not that much more then 7075 but has significantly better strength properties. You just have to use it in high stress locations.

No one has guessed what its for yet.

[AdamHeard]

The background looks like a sheet of black ABS plastic.

I'm pretty sure they use that for their electronics so that could be why they have it on hand.

It also might be the tables you see in these pictures here.

[Kirk]

Its not tables and its not ABS but it is a type of plastic and it is going on the robot.
