Meet our Robot!
Our robot from the 2017 competition was irregular for the team. In every season since 2016-17, the team has created a robot capable of performing nearly every task on the field, usually through an elevator system that reaches every height on the field. However, during this year, we took a big risk and built a robot completely around one mechanism of the game: fuel. The robot would pick up fuel at a very fast pace, sort the fuel so it is moving through the robot at around 1 fuel per second, and then shoot the fuel through a 3-d printed mechanism, adjustable in-game through motor strength.
The intake was a central aspect of this year's robot. In the field for this game, there were many boxes of fuel, and at almost all times in a game, there was a large amount of fuel on the ground. Robots that were able to pick up fuel the quickest were at an advantage, since there was a limited supply of fuel. Our intake was capable of sucking in as much fuel as could fit in the width of the intake (which took up the entire back of the robot) at all times. Upwards of 10 fuel could be inputted every second into the robot's interior.
Once the fuel reached inside the robot, a sorting mechanism would ensure that only one fuel entered the shooter at any time. If more than one fuel entered the shooter, it would jam the system, and if fuel were being fed in at too quick a rate, the friction from the ball would slow down the motor for the shooter enough so that the next ball would be shot out slower and thus travel less. In essence, to promote the accuracy of the shooter, the sorting system kept the fuel entering it at a constant rate.
The actual mechanism was a circular rotating object with compartments that fit one ball each. It rotated from where the intake spat out the balls to where the balls exited for the shooter.
The shooter was the final aspect of the scoring mechanism. The robot would line up with the ship in the center, aim towards the target, and initiate the shooter motor and the sorting system motor. The fuel would pass through the shooter and exit the robot at great speeds and reach plenty high to score. In the end of this process, there was no fuel remaining in the robot (or a small amount).
