The 2017 season brought a series of great experiences and challenges for both members and coaches. After returning from a trip to China, our team was met with a challenging and multi-faceted game that required much prioritizing in order to successfully complete all tasks. Our drive base and frame were CADed by students, a definite feat for our team. We embraced the game theme by making steam punk daisy headbands, which were sported at each competition. Also joining us was Superintendent Crisfield and President of FIRST® Don Bossi, who both visited our pit at different competitions. Though the game presented several challenges, our team pulled through and had a great season, with plenty of learning opportunities.

  • Java robot code with “DaisyCV” vision processing
  • Closed loop PID control is handled by Talon SRX in conjunction with CTRE Magnetic encoders to control turret position and flywheel velocity
  • Preplanned trajectories for each autonomous mode
  • Sophisticated goal tracking to ensure the boiler’s position is always known relative to robot position and heading


2017 Game Challenge, FIRST® STEAMWORKS

This years FIRST® Robotics Competition game invites two adventurers’ clubs, in an era where steam power reigns, to prepare their airships for a long distance race. Robots collect fuel (balls) and score it in their boiler via high and low efficiency goals. Boilers turn fuel into steam pressure which is stored in the steam tank on their airship – but it takes more fuel in the low efficiency goal to build steam than the high efficiency goal. Robots deliver gears to pilots on their airship for installation. Once the gear train is complete, they turn the crank to start the rotor. Robots must latch on to their airship before launch (the end of the match) by ascending their ropes to signal that they’re ready for takeoff.
