This is the last thing that we did today. The body was not that complicated, it just had a ton of screws that had to be tightened. As the manual stated, a little patience is required to make all the slots line up on many of the parts. This usually isn't a problem, but after working on something for a few hours, patience wears thin. Luckily, I have a really good student assisting (good with computer science, electronics, and more), and she has me for two hours back-to-back. This really helped move the project along today!
