Hanging Hook Prototype By Abhi, Ethan, Justin, and Janavi

Task: Design a hook for pulling the robot on the lander

Today, we designed a basic prototype to hang the robot. We designed it, like all our parts, in PTC Creo, and printed it in nylon with ~80% infill. The hook was designed to minimize material used while also being strong enough not to stretch over time. First, we tested it by hanging ~20 lbs of material off of it for one minute. This worked, but a little too well. While the nylon piece remained undamaged, the metal bracket it was supported by bent at a ninety degree angle. So, we had to pursue further testing.

For our next test, we plan to hang a mass outside for a week. Dallas weather has been extreme lately, with a lot of rain, humidity, and heat. This will be the ultimate stress test; if one of our pieces can survive the outdoors, it can survive just about anything.

Next Steps

We're probably going to have to reprint this to be a bit more fitting for our robot, but its a good start and it works great so far.
