We are (a couple of computer, electronics and control engineers) as a
amateur/hobbyists who want to build a Mars rover (or something similar)
mobile robot for fun.
Our main interest is not its mechanical design but its control, comms, and
software.
We do not have mechanical expertise in our group, but we have good relations
with very talented machine shops who can build the mechanical parts for us
if we can provide detailed mechanical design (CAD files/drawings).
Now the obvious question;
Do you know any open (publicly available) mechanical design documents
(CAD files) to build a Mars rover ?

I believe that the design is patented by JPL. See
http://www.magneticpie.com/LEGO/techNotes/MecTherMob.html
for some more details of the mechanism.

US Patent number 4,840,394. Google on "wiffle tree" and "suspension"
together to see why it's invalid. These suspension arrangements were
thoroughly investigated in the 1950's. If you wanna build one, go
ahead. No-one at NASA's going to sue you - but watch out for Mattel!

CAD files, good luck. You might have some trouble finding the easy
solution, but try searching on "rocker bogie" ...
http://www.google.com/custom?q=rocker+bogie
Eg, not too much here, but it does mention specific parts used, etc ...

Requoting the original post:
How much is that going to cost? Or are the machine shop people
interested in this as well, and want to donate their parts/skills or
offer them at a substantially reduced rate?
There are many robotic platforms available which probably cost less
than having custom machining done, though I don't know of any that are
very similar to the Mars rovers.
How close to the design do you want?
That site mentions Maxon motors. Here's something from the Maxon
site:
http://www.maxonmotor.com/index_a.cfm?mode_redirect=page010200.cfm&globalsearch=true
According to that page, each rover has 39 motors. Perhaps you
should make a Sojourner, it only uses 11 motors. :)

high price and absence of good mechanical skills.
Here is a link to Washington State University Robo-Magellan project
http://www.mme.wsu.edu/~wsurobot/magellan/ started recently that is similar
to Mars rover, but simplified I would go for.
