Marshmallow/candy robot: Elon
To make the robot we took off the gear collector off our competition robot and used lawn sprinkler valve to control the airflow, black iron pipe to store air before shooting. This prevent air pressure to be stored in the PVC. We added PVC pipes to create cannons held and shot the marshmallows along with some pneumatic. Toilet paper was used to make a good seal against the walls of the PVC pipe because without it the air would escape through the marshmallows. We coded it used pneumatic in Java. The marshmallows went pretty far. About 8 feet. We blocked off an area and gave kids nets to try to catch candy or marshmallows. We kept the same name for the robot, Elon.
Please note: Elon will most likely be current under construction so we can provide more fun but will be returning to future events
