Logan Weekes and Jack Estes (team 31337D) James Salvant Robotics 6th Period 1/1/19 AUTODESK Design Challenge For this years CAD Engineering Challenge, my team and I decided to a peice that although looks very simple, it has many uses and is a multifunctional piece. By making this piece, we are improving the structural support on robots as well as making it simple and more efficient to create and x-drive chassis. For example, if you have two vex iq two by x(any value) beams that intersect at a 90 degree angle, then this piece can be used to support them more effectively than using corner connector pieces. Its second function is to help build as simple and more effective xdrive chassis. X-drives have starting becoming more popular throughout the vex iq world, but the only problem with these intricate chassis's is that they are very complex and hard to make. Our goal with this piece was to make xdrive chassis's easier to build and use by every Vex Iq robotics team.     To design this piece, we used newest version of Autodesk Fusion 360, and we found that this software was very easy to use and user friendly when designing this piece. Before this online challenge, I mostly resulted to using Autodesk Inventor Pro 2019 for design parts, assemblies, and animations. But for this project I decided to try out Fusion 360 and I was happy with the results that we produced with the software. As well as designing the part on autodesk, we 3D printed a prototype of the piece to see what it would look like and how it would perform with other vex parts. Below are pictures of the Design in Fusion 360 and the part after it was 3D. We used an Ultimaker 3 extended to print the piece out. Since the holes weren’t exactly perfectly printed, we used a drill to smoothen them out and allow the pins to snap onto the piece. Also the scalse size we used when we put it into the 3d printer software was x = 119.8mm  y = 119.8mm  and  z = 25.1mm. Overall this was a very enjoyable project and I am looking forward to seeing what other students come up with to compete against. I will defenitelly keep using Fusion 360 in the future along with inventor for other new vex parts and crazy new pieces that Jack and I come up with. Thank you for reading our summary of our piece and we hope you enjoy and find it practicall/usefull.
