In order to improve the functionality of our robot, our team designed a new VEX part that resembled two C-channels connected together, thereby accepting the CAD Engineering Challenge Sponsored by Autodesk. Learning from our past competitions experiences, we recognized that our robot required more base stability and speed in order to guarantee more wins. With this in mind, our group aimed to make the base as lightweight as possible while maintaining stability. The new VEX part utilizes less metal which results in more speed, while providing more stability. This part can be used in a variety of ways on a robot, but the key intent is for creating a more stable drive. Motors can be placed on the outside and because it is a solid piece an axle can pass through the part perfectly straight. This improves how straight the robot drives, the robots efficiency, and how consistent the robot is. The piece would fit nicely into the chassis of a robot because it is large enough to fit two wheels within it but it also is below the 18 inch size restriction used on competition robots. This part was created using Autodesk Inventor 2016. I started out by creating a single 1x2x30 c-channel with no holes. I then created half of one of the connecting sides and mirrored it once on the x-axis so that I had one half of the complete part. I then mirrored it again on the z-axis to give the completed structure of the part. I then proceeded to use the pattern tool to create the holes on all sides of the part, completing the part. From this project our robotics group learned that there can always be innovations to even the simplest of parts. It would be convenient for our group to use a 3D design software program in the future. We could use it to bring our ideas to life and show each other not only new VEX parts but new robots that could be successful in various competitions. A 3D design software program like Autodesk would definitely help anyone who is on a competitive robotics team because it allows creativity and lets anyones ideas be seen in 3D form. Learning how to utilize a 3D software program would help any young engineer in a future career. One could used the program to communicate their ideas to fellow colleagues or use it to show their clients ideas that would fit their request.
