WRV1 Progress

Jörg from Switzerland has made some exciting progress with his WRV1 rover prototype. The CAD design for the wheel and gearbox was posted earlier and here are the first pictures of the manufactured parts for the wheel.

First Jörg had to create some tools for being able the produce the cut metal sheet parts (thickness 0.8mm), so on this picture you see some tools and the parts in the order of the production. In front the cutout sheet metal (AL), the outside bended, the fixture bended and finally the holes reinforced:

A closer look to the tool allowing to reinforce the holes by beading the borders:

And here is the result of about 15 hours of preparation and 4 hours of production (some steps are to be optimized!!). The whole wheel weighs about 23 grams (with brass pins instead of Teflon pins):
