We created a very rough prototype for the hang mechanism, which was a model box to represent the robot. Cinderblocks were added to show the weight the robot will eventually be. This model was used to perform various tests.

We created our hang prototype. Our prototype consists of 2 different types of arms that are either vertical or angled in order to grab the high and traversal bar. One set of arms is stationary with hooks that latch over the bar. The second set extends and pivots in order to grab the next highest bar. We prototyped both bars at half scale and will test the swinging motion Saturday.

We had a big discussion with the rest of the team and described how we are going to work hang. It will have a set of 2 bars that will only move forward to offset the weight of the robot to keep it from swinging and have two arms that will reach out and grab the bar to retract by means of a spring. Both arms will pivot on the same point and will be connected by spring to bring them back to each other.

We had a group discussion about robot real estate and what we needed to determine in order to continue. We continued with a lot of math to determine the necessary lengths of the arms.

We worked in two groups, one of which worked on CAD-ing the winch assembly with the disk break and the other making a hang assembly. Group one modified our winch assembly from 2020 and added our disk break with calipers from 2018. After creating a new disc break and new parts to mount the calipers, we are almost done with the assembly. Group two assembled a CAD hang using the arm lengths we determined yesterday.

Today, we stayed in our two groups, finishing what we started yesterday. Group one continued our winch assembly and group two focused on mathematical calculations. After some revelations at integration, we have a long to-do list of things to modify, including the ways our arms will snap together and the mounting of our disk break.
