The Great Mojave Rover Version 1.0

thingiverse

Update: 2019/06/23 VERSION 5 design. I've been putting in the time and effort to perfect the rover's design. I'm confident that this version will be able to withstand the harsh conditions of the desert. Check out the video here: https://youtu.be/9SWO8IDX3os. Once it's fully functional, I'll post an update with all the latest features. Update: 2018/09/02 I've made some significant upgrades to the corner spindles, adding a bearing and a modular design that makes them even stronger. This will be essential for the version 3.0, which I believe has what it takes to withstand the desert conditions. As soon as version 3.0 is complete, I'll post an update with all the details. I'm excited to share this new version with you and see how it performs in the harsh environment of the Mojave Desert. Update: 2018/08/31 I've started working on The Great Mojave Rover 3.0, printing it with PETG, which is giving me amazing results. I'll post an update once I have a fully functional rover again. Update: 2018/08/05 If you plan to use this rover in the summer, make sure not to print it with PLA. It melted after just 2.5 hours during my last test. However, it works perfectly when the weather is nice. The Great Mojave Rover Project is an autonomous rover designed to survive the extreme conditions of the Mojave Desert. Inspired by JPL's Mars rovers, I'm taking this experiment to the next level by leaving it in the desert for weeks or even months at a time. I'll be controlling it remotely and transmitting data via LTE. Check out the video here: https://www.youtube.com/embed/1WbNJOvi_eU. This is the first rolling version of the rover, but a new one is already on the drawing board waiting to be built and tested. I wanted to release this version first to gauge your reaction and get feedback. The Great Mojave Rover is designed to print on small printers with a 150x100x100 print area. You can rotate the part for optimal fit and most parts can be printed without supports.
