This is a robot design created to compete in NASA's centennial challenge, sample return robot challenge. It is essentially an excavator on a drive that is modeled like the rocker and bogie geometry of the mars curiosity. The name curivator sums up both ideas into one robot to do the tasks in this challenge.
We have released CAD here:

Or alternatively
this zip retains the folder structure of the parts:
We hope that people may find use for some of the parts from this release. We have tried to push the envelope on what can be done for 3D printing... in particular check out the 3D printed linear actuators, 3D printed thruster bearings, and 3D printed mounts for camera's and RSL.
Comments are welcome as we are still learning and trying to improve... Thanks.
If I run into some of your team's student coaches/drivers on the field of battle someday, I still might ask 'em what they're doing after high school. :) - Ken Patton [more]
