After more than 5 iterations on the suspension columns, the first prototype of the tread assembly is on its way to being completed. Many components are still in their first generation, including the acrylic spar, roller wheels and skids, and tread sprockets (not attached). Future work on the spar will involve waterjet cutting it out of aluminum and adding additional support for structural spacers.
Even with this partial assembly, we can already begin to draw some insights into the successes (and potential problems) of our design. Currently, we are optimistic about the strength of the 3D printed components and the spacing between parts. Initial tests of the suspension have also shown greater friction than anticipated, likely due to the tight tolerances in the suspension column leading to friction between the layers of adjacent walls. However, we believe these issues do not pose a significant risk to critically compromising the performance of the system. Our next steps include more standardized testing and assembly of the remaining components.
