Students Experimenting with Tension/Compression Joint Articulation
Date: 3.1.17
Goal: Use Vex gear to simulate different joint articulation options based on a steady cam.
Location: Logan HS
Time: 3rd hour DE class
Students: Mason, Alex M. and Vaeng
Students were given some research illustrations on different types of Exo Arm assemblies. We were attempting to scale it down and replicate the movements to determine if we could used it as a possible solution for the Exo Arm. Students used Vex parts to quickly put together a section and then used springs and rubber bands to determine resistance and tension forces.
