I will study your suggestion.
There is something really important that we need remember. The students
must have some equipment to scan and than they can begin reverse
engineering. The students already have information about equipment that
As you have said, I need determine the objectives of the contest. Solve
a problem could be a good option because I could choose an equipment that
works badly. Maybe equipment that works well and we need another one to
Time, limited set of material, limited building iteration, RP technical
parameters (accuracy, surface finish, and others) and structural analysis in
CAE could be good points to determine the objective, the rules and evaluate
the projects in the contest.
A solution to a structure that carries something to a point is a very
Someone else has more comments or suggestions?

> A payload could be an egg (unfrozen / unboiled of course) . The objective
is to have the egg transported (shot from an air cannon) as far as possible
without breaking. You have to decide if the transport system has to be
reusable. So the idea is that you have a 4" diameter air cannon operating at
60 psi that is going to eject the machine and payload. The students have to
devise a packaging that will allow the payload to be launched and not
damaged of landing and the one that goes the furthest on two shots wins
> RP could be used as a build system for the structure which adds in
determining the properties and working within the boundaries. I see the
systems having to be articulated for the landing phase. The limitation could
be to have the system fully designed in CAD before building and limit the
building to 3 iterations.
