Competition Season Meeting

CAD & Design

Final decision to use tracked tank drive had been made via email conference during the snowstorms. Mentor Andrew Weissman summarized the team's thinking an a 23-Jan email:

My thoughts on the drivetrain decision:

Based upon the evidence presented by both the video from 1635 and our modded kitbot, both are able to drive over Category B and D defenses. However, the 8WD bot showed considerable difficulty driving over the moat at a level consistent with what is required for this game (at least that was the impression I got driving over it). Also, while driving over some of the obstacles, the bounce experienced would be enough to potentially cause removal of a boulder from robot possession (depends on other mechanisms). This problem was exaggerated by the lightweight nature of the 8WD bot, but may still remain present with a fully loaded bot(mechanisms-pending). The tread drive appeared to climb over all Category B and D defenses without much issue (except the ramparts, but that was a design flaw with the robot they used with having too low of a bellypan).

I still believe that the treads pose a considerable risk, but the 8WD did not perform as well as required for this game with all B and D defenses, making the treads a better option for crossing the defenses.
