Gryphon: MRDT 2017 World Champion Rover by ELSansone

Last crawled date: 3 years ago

This is a 0.11 scale model of the University Rover Challenge 2017 world champion rover: Gryphon, by the Missouri University of Science and Technology Mars Rover Design Team. Go check out MRDT's website, Facebook, twitter, Instagram, etc, for information about Gryphon and the new 2018 rover, Atlas.
Much of Gryphon's success can be attributed to its revolutionary Mantis suspension, which enabled it to roll over boulders and ditches without a pause. Granted, the dual action gas springs aren't possible in printed plastic at 0.11 scale, but elastic does alright for a model on my desk. Some files require support material, and I've included two files for those. One is the simple part, and the other includes support material I've added. Its minimal, and designed to peel off easily. This is recommended, since at this size its well nigh impossible to get auto-generated support off.
I plan to make the robotic arm at some point as well. I'm still on the fence about populating the interior of the rover, as there are a lot of boards and bits in there. I did the power box and battery pack, but as the Power Systems lead for 2017 I am biased.
There will be an assembly guide at some point, but it may be a while. You can always go look at pictures of the real thing. TBH most of you who are interested in printing this are MRDT members or alumni, so you should be familiar with how it goes together. If you have questions, ask me.
Part quantities and notes:
Frame x1
Back, middle, and front covers x1 each. The front frame prints best laying flat.
Wheel x6- there is a cup inside the wheel that slots over the "motor" part of the A and B links, be careful to not remove this while removing the support material, or the wheel wobbles a lot
A link x4
B link 1 x2
B link 2 x2
C link x4- The fancy CNC work on these is so Iconic I thought it should be kept in.
Suspension Axis x2. I find it helpful to scale these along Y by 2, then trim them as needed, depending on how well your C links fit.
