Initial Thoughts

Before Team α and Team Ω met as Team K, they independently thought of very similar ideas for their robot armj designs. Both teams felt that rounding either the shorter knotch in the robot arm or both knotches in the robot arm would be a positive way to reduce mass and redistribute forces, resulting in less stress.

After hearing about the first commercial jet liner, the De Havilland Comet, in class, neither Team α and Team Ω wanted to use sharply angled cuts. The De Havilland's square-cut windows gathered immense stress. This approach to the robot arm did not appear optimal. Hence, Team α and Team Ω used their separate design times to experiment with extruding rounded cuts.

Initial Design

Team α used the "spline" option to completely remove the side of the robot arm with the shorter knotch, resulting in a curved side. After experimenting with extruding arced slots, circles, and ellipses, they extruded a single ellipse. However, there was not time enough to finalize Team α's design. What resulted had a volume of 1.1 cubic inches and a displacement of .1660 mm, resulting in a scpore of .1826 mm-in³

Team Ω made circular cuts to both knotches, rounding the knotches' edges and leaving the sides intact.


Group Design

When members Seth, Cosmo, and Olivia met on Saturday morning as Team K, they initially spent time separated, experimenting individually.
