Work Day on Exo Arm Base and Joint Articulation

Work Day on Exo Arm Base and Joint Articulation

Date:2.28.17
Time: 8:30 AM - 2:00 PM
Location: Logan Welding Shop
Students: Alex M., Mason, Alex R., Trenton, Ben, Andy, and John.
Instructors: Johnston and Pitz

Students came in on their day off to work on the Exo Arm. We built a base to support the linear rail and braced it up. We also spent quite a bit of time working on the joint articulation on our test model. Alex and Mason tried a number of spring combinations to see if they could get the arm to move in the direction they wanted to while mitigating the load. Results were mixed. We looked at other options for the joint articulation. Progress was also made on the shoulder joint and 2" slew ring bearing. A receive had to be turned down on the lathe to accept the slew ring bearing.
