<div dir="ltr">Jeff,<div>     Here is another good article discussing "CADRE"'s purpose (see: <a href="https://www.nasa.gov/directorates/spacetech/game_changing_development/projects/CADRE">https://www.nasa.gov/directorates/spacetech/game_changing_development/projects/CADRE</a>). I wish they showed their rover design a bit more. It looks to have a lot of 3D printed parts in the prototype. Other observations are that each wheel is driven by an individual motor like Dagu Wild Thumper designs (see: <a href="https://www.pololu.com/product/1564">https://www.pololu.com/product/1564</a>) and the top of the final rover, not the test rover, is to be covered with solar cells (see: <a href="https://www.autoevolution.com/news/autonomous-rovers-being-tested-in-the-slope-nasa-to-3d-map-the-moon-with-them-173419.html#agal_4">https://www.autoevolution.com/news/autonomous-rovers-being-tested-in-the-slope-nasa-to-3d-map-the-moon-with-them-173419.html#agal_4</a>). I wish we had a better view of the rover's suspension. That is the design feature that really interests me currently.The rover shown in the article doesn't appear to be a folding robot A-PUFFER variation.</div><div><br></div><div>    NASA seems to be really investigating the idea of multiple small robots launched from the delivery vehicle after landing (A-PUFFER and CADRE).  </div><div><br></div><div>Regards,</div><div>Doug P.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Nov 4, 2021 at 8:09 PM Jeff Koenig via DPRGlist <<a href="mailto:dprglist@lists.dprg.org">dprglist@lists.dprg.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>I thought this was interesting.  This is the first time I've heard of NASA's "CADRE" project, and I'm hoping to learn more about it.</div><div><br></div><div><a href="https://www.jpl.nasa.gov/news/a-cadre-of-mini-rovers-navigate-the-lunar-terrain-of-slope" target="_blank">https://www.jpl.nasa.gov/news/a-cadre-of-mini-rovers-navigate-the-lunar-terrain-of-slope</a></div><div><br></div><div>Best Robo-Regards,</div><div>Jeff<br></div></div>
