Sci.Engineering.Design: Mobile Kitchen

Manipulating the robot arm in a restricted space is going to require complex movement planning calculations, or the arm's "elbow" will constantly knock things off benches.

Yes, that's important also. But first thing is the material. For example, lexan is strong enough, but too flexible and easily scratched. So, perhap s CnC coatings to protect the surface.

Look at ribbed design as used in molded fork-lift pallets, and the like for shaping ideas. There is some rather good stress-analysis software that can be applied to designing of shapes, before molding..

I think you are trying to optimize a design as your first step. Why not wait until you have "nailed down" more of the design? How heavy would a conventional trailer be? I've seen plenty of kitchens for cooking at fairs and such that seem to contain plenty of heavy equipment and use very conventional materials. It's very likely the trailer will be lighter than the contents.

But KUKA, the robotic arm would be heavy, probably several hundred pounds b y itself. Expandable panels also require tracks, rollers and motors. 3000 pounds trailer can probably handle 1500 pounds payload.

Yes, that's why we need expandable panels, or even cargo bay on top, to all ow for plenty of spaces. And of course, plenty of sensors and cameras.

Did some rough estimates.

Using 400 sq.ft. of 16 ga (1/16) sheet:

Steel: 1000 pounds for $500 Aluminum: 300 pounds for $2000 Lexan: 150 pounds for $1500

Might end up with different thickness, but these are the relative numbers.

I don't really understand why you are trying to design this from scratch. I can't imagine there aren't vendors who supply exactly this sort of thing that you can't get some basic info from about what they can and can't supply. You aren't trying to make the robot yourself. Why try to build the trailer?

Rather than worry about designing a super heavy duty but lightweight trailer, I would try to find vendors who make the other equipment lighter and then discuss this with trailer companies.

Yes... pay the experts. I'd start by putting the heavy stuff over the truck bed, the lightest stuff in the overhang. Work out what weight needs to be handled where, with what margin. Look at avalable panels etc etc. But why?

If this is going to be a back yard build, OSB3 is cheaper than ply.

There are some designs around, but most of them are heavy, upward of 2000 p ounds. They emphasize on the space, rather than the weight.

Yes, we are collecting info on what we want before taking it to a trailer m aker.

OSB3 is heavy. I think plywood can be thinner. Perhaps CnC coatings (like harden paint) on thin plywood.
