Prototypes are a huge part of our build season; through the rapid creation of different proof-of-concept prototypes, we are able to more effectively decide on a final design. This year, we tried three different materials to create prototype shooters: pneumatics, surgical tubing, and a simple, motor-driven catapult.
It’s the best six weeks of the year again! During the FIRST Robotics Competition kickoff, the 2014 challenge, Aerial Assist, was reveled. This year, teams will be working with other teams to carry 24-inch game balls down the field, over a truss, and into a goal.
Early on in the first week of Ultimate Ascent, we decided that we wanted both a Frisbee shooter and pyramid climber. But how would we do it? Our climber design transitioned through various designs before we assembled this ten point climber.
For this year’s FIRST Robotics Competition, Ultimate Ascent, we knew that we had to be quick if we wanted to both shoot Frisbees and climb the tower. Thus, by week two, we had started on our shooter prototype and by the end of the fourth week, we had completed assembling our shooter.
We were rather surprised not only by how powerful the shooter was, but also by how successfully the hopper performed. The piston and the Frisbees worked flawlessly together, which will hopefully help our robot shoot more consistently. Overall, things seem to be going well.
Our robot chassis this year was design specifically for size and spin. We needed it to be small, strong, and compact as there is very limited space this year and we decided to add two omni wheels to allow our robot to aim more efficiently.
Our prototype Frisbee shooter for Ultimate Ascent overcame several different prototypes to reach its final version. During the course of the first week and a half, we designed and assembled various designs and configurations of our flywheel design.
