We have been working hard on the rocker-bogie suspension system for the Spirit II, our Mars Rover. In this picture, the front wheel will be attached on the left side. The two back wheels will be attached on the right side. The two back wheels will be connected together by a tube that pivots on its center. The entire thing pivots on a central shaft (connected at the junction second from the left) that goes through the counter-rotating differential to an identical chassis frame on the other side of the robot. We are building the chassis frame out of .625 aluminum tube, tube connectors, and aluminum plate. It takes a bit of imagination at this point to visualize how this is going to become a Mars Rover, but it’s coming along. If it all actually works, we’ll be amazed.
Mars Rover Chassis – in process
That arm is beautiful. Did you use Lynxmotion parts? Please keep posting pictures and details of the build.
I have a few pictures of the mars rover if you want them. I have set one as my desktop since it is so cool. Send me an e-mail and I’ll put them in a DropBox folder for you.
Keep up the great work!

Migs, Thank you! Although it’s mechanical in nature rather than electrical, it’s one of the neatest things we’ve built. We were very happy with how it turned out. Check out this page, where there are more details on the Mars Rover: https://beatty-robotics.com/spirit-ii-mars-rover. There is a list of materials there, as well as links to some of our other Mars Rover-related postings. The parts come from various places, including one or two from Lynxmotion, but some of the main tubes and connectors come from ServoCity. We had to cut and modify them of course, but those helped us get started.
pls send the pictures to my mail sreejith_9988@yahoo.com
