This automated trophy was created for the 2015 FIRST Robotics Recycle Rush FRC game. The trophy features SureStep Stepper motors and stepper drive to create a memorable trophy for the 2015 Georgia FIRST Robotics off season GRITS event.

This trophy was shared across two offseason events in 2015: GRITS and XBOTS. This has the XBOTS nameplate but it’s the same trophy that was used for GRITS. There’s not much you can do with pool noodles, so we stuck some wood pegs on some stepper motors and pool noodles on those, so they could spin around. This three-position joystick serves as the speed control for low, medium and high speed and this selector switch chooses forward, off and reverse. If I flip the trophy over, we see one stepper drive, three stepper motors and a power supply. The forward and reverse switch switches the direction pin on the stepper drive. This stepper drive has an analog input, so the speed switch simply switches different sized resistors into the circuit to change the analog input voltage level which changes the speed of the motors. This stepper drive is very capable, so we are running all three stepper motors from the same drive. And since there isn’t really any load on these steppers, a small 24 volt, two-and-a-half-amp power supply is more than enough. The Lexan base was bent using a hot wire heater. Pre-cutting V-grooves in the plastic ensure nice straight bends. Throw on a laser engraved nameplate and you have a super simple – and a little silly trophy for the recycle rush offseason GRITS event.
