Fabrication
The primary method of fabrication was the use of a LaserCam to cut masonite (the primary structural material). Pieces that needed to be glued together (primarily just the shooter module) had tabbing to fit together like puzzle pieces. The only other method of fabrication used (besides hand drilling and filing) was the use of a lathe to turn a motor-wheel adapter.
The robot was designed on SolidWorks and is comprised of four modules and the team conveniently had four builds, each time adding a new module. The four modules, starting in order of the builds were:
This design was truly modular, as none of the four modules were glued together. The two platform plates that sandwich the drivetrain base were especially easy to take apart, as they were held together by nylon standoffs.
