Working Drive Modules!

Yesterday we all put in a long day of work and were able to build 5 complete, working drive modules.  These modules are the centerpiece of our innovative mobility system and represent a significant milestone in the rover construction process.  We picked up all of the machined components from our sponsor Dav-Tech Plating, where they received a MIL-DTL-5541 chromate conversion coating.  We then crimped the necessary pins on our Maxon motors (17 wires in all) to interface them with our TE Connectivity circular connectors, added a Maxim 1-Wire digital temperature sensor, and installed them in the watertight structural housings (welded by Jake at Barnstorm Cycles).  Final assembly of the bearing housings and lip seals, followed by 10 minutes of break-in testing, completed each module.

We want to say a special thank-you to everyone who has gotten us to this point, including our advisors Prof. Padir and Stafford, and our sponsors Maxon Motor, Barnstorm Cycles, and Dav-Tech Plating.
