Prototyping Protective Cones – February 7, 2015
To provide protection for the intake motors at the ends of the intake mechanism, protective cones have been designed. The ultimate goal is to produce them using the 3-D printer. Because the 3-D printer supplies are costly, the team opted to prototype with a vacuum-molding process. The prototype was designed in CAD. The mold was cut into foam on the Shopbot and then smoothed and covered with aluminum foil to prevent melting of the foam during the vacuum molding process. The molded cones (made of a thin plastic material) were then installed on the robot for testing. A few modifications have been made to allow for wiring and testing. Any modifications will be added to the CAD drawing to ensure that the final design is available for the 3D printing process. Laura Lee and Everett were the key design/production managers on this project, with assistance from Mr. Derry, Mr. Trudeau, and Mr. Goss.
