Because we want our robot designs to be lightweight, we’ve decided to go ahead with aluminium tubes and wood sticks for the structure. By far, our intention is to use 3d printed joints and small ball joints.

I just want to share a little bit of how our prototypes are looking so far:

Rhino 3d Modeling

Andrés analyzing ball joints

As you can see we found a solution for our joints using small ball joints used commonly for scale model cars and later on we discovered they are also being used for Rep Rap printers.

In Barcelona we could find these little things in FaSol Store, dedicated to scale model cars.
