New WRV1 Lunar Rover Mock-up

Here is a new WRV1 lunar rover mock-up from Jörg using the new state of the art wheels, the steering unit and... Stokys (erector set) for the rest. As you can see, there is even plenty of room left for electronics :-)

Finished WRV1 wheels

I can tell you Jörg has been busy this week but now he has finished two wheels for the WRV1 lunar rover (and we still have the prototype with the disc hub). Have a nice weekend everybody - we'll be back next week with more news.

WRV1 Wheel Hubs

Jörg has now finished manufacturing four wheel hubs for the WRV1 rover prototype. For reference, I have also included the blueprint that has been posted earlier. Personally, I am very impressed by seeing the real thing look like on the specifications - I wish we could do the same in the software world ;-)

Updated wheel hub and blueprints for WRV1

It has been a busy week both at my daytime job, which pays my bills, and my nighttime job, FREDNET. In the meantime Jörg has uploaded an updated wheel design for WRV1 as well as some blueprints hoping to find people who can help manufacturing the many parts. So, GLXP fans, here is your chance to help building some hardware for this cool lunar rover prototype! Let us know if you can help.

WRV1 Wheel Prototype Assembled

Sitting in my apartment in Denmark on a cold winter evening, I can only wish I was in sunny California for the Google Lunar X PRIZE Team Summit. Fortunately, I can listen to the discussions via Fred's VOIP and talk to him via Google chat despite the fact that I am more than 7000 km away.

At the same time, exciting news keep coming in reporting progress on the rover side: Jörg from Switzerland has now assembled the first wheel prototype for his WRV1 rover. The current weight of the wheel is 96 grams but the wheel support will have to be cut out so it will come down to about 60 grams (for the prototype).

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):
