Most Critical Module Completion

We chose our drive train to be our Most Critical Module because without motion, our bot would not be able to carry out our strategy or get any points, which would lead to instant defeat. For our drive train, we decided to have a tread system. This system would help with traction when trying to climb the back of the arena, while still ensuring maneuverability. We were able to complete our engineering for our Most Critical Module by the due date of November 11. This included the solid models, part drawings, bill of materials, and analysis. From November 11 until November 21, more calculations were done, some specs for the parts of the MCM were adjusted, and we were able to manufacture 3 parts in time for the MS7 due date of November 21. The parts that we manufactured to our specifications and drawings were two sets of pulleys, which we made using 3D printing, and our tensioner shafts, which we used the lathe and drilling processes to manufacture. These parts were checked off in lab and met the specifications of the edited drawings.



As for future machining and progress on our bot, since we have completed our manufacturing for our MCM (drive train), the next component of Autobot that we are going to be working on is the roller. The roller will be molded out of silicon. The mold that we will be using for this is going to be made by a 3D printer to the specifications we desire. We will also be creating the roller insert, which stiffens the roller and transmits the driving force.






Here are two images of the components of the roller that we will be manufacturing.

There will be some difficulty due to Thanksgiving break, but our group has been good about communicating and determining times to meet that would cause minimal conflicts. Pictures of the molding process and construction of the roller component of Autobot will be posted shortly after the roller has been completed.
