One nicety about how the robotics system generally works, is that when some things take a while to really nail down and get right - that extra time in the beginning can save a lot of time at the end. In week 6, we started reaping a few rewards, and watched as a pile of parts transformed, very quickly.

Our process for mechanically building the robot is pretty simple - start with the superstructure, then when that's done, fasten everything onto it. Our individual system build methodology is also simple - dry fit the parts, then finalize the parts. For dry-fitting, we have two primary options - Cleco's are temporary holds for rivets, they can be inserted and removed, and hold with the same grip and diameter as the eventual rivet will. For other fastener types, we use standard nuts and bolts, which we can tighten, then remove as needed.
As we validate the dry fit and prepare for final assembly, we remove Cleco's and install rivets, and for bolts we have several options - nylon threaded bolts, nylock nuts, and loc-tite. These solutions are all to mitigate the effects of vibration on our installed bolts.
As always - enjoy the pictures!

| Start with the CAD, and the parts, then put them together like Legos! |
 |
| Thursday night - literally 5 minutes of work to get this put together, having all the completed parts on hand. |
 |
| Mechanical and electrical teams are able to work on the structure in tandem. |
 |
| The tower is super clever - it connects to the base of the robot with just 4 bolts, and we are using (a few) power disconnects, so that in ~2 minutes we can remove the entire top half of the robot for maintenance or any other needs. |
 |
| Saturday evening - 4 days from boxes of parts, to an 80% complete robot. (Still work to do!) |
 |
| Our intake was the final subsystem in design, and final subsystem for parts manufacturing, and by Saturday night we had it's first dry-fit onto the robot. |
