This year, our robot Coraline featured a polybelt ramp to intake and index pieces of Coral into the outtake. A 3-stage elevator then lifted the game pieces to Level 4 of the reef, capable of also scoring on Levels 2 and 3 on the way. Unfortunately, our climber broke at our first competition and had to be removed for SFR, but we're working hard on getting it back on again in time for CalGames in the fall!
This season, our bot (named Sunny Turner) focused mainly on swerve! In order to facilitate the first season of using our own custom-built swerve drive train, we decided on a simple mechanism to score notes into the Amp and power-up our alliance partners' scoring. We call this mechanism the "spatula." Additionally, we used a rack-and-pinion climber to score points in the endgame.
During the 2022-2023 season, our bot Lamarck featured a long telescoping arm with a flywheel grabber designed to move both cone and cube pieces across the field. With our trusty West Coast drive, we scored high points while prioritizing reliable movement and defense.
Plus, our bot looked better than ever! Using LED strips and laser-cut acrylic, we showed our 4904 pride on the field for every second.
During the 2021-2022 season our bot focused on a 360-degree turret and high-precision shooter. We used the previous year's West Coast drive train for simplicity, focusing our efforts on consistency and point-scoring.
Later in the season we added a climber, which pulled up the bot like arms.
Our 2021 game, Soup Scramble, required robots to collect various ingredients—carrots, potatoes, and mushrooms—and place them into a bowl to fulfill randomized orders. In autonomous, teams earned points by collecting 3 ingredients placed in front of their robot at the beginning of the match. The endgame consisted of robots climbing onto the “bench,” which scored a 20 points.
In the 2020 season we implemented a tall indexer for power cell storage, as well as an adjustable hood for multiple shooting distances. Sadly, the season was cut short when COVID struck. Before the bot could steal the show of any major competitions, the season ended.
Our 2019 robot, Penelope, used a claw and arm mounted on an elevator and 4-bar linkage to collect and place cargo and hatch panels at all heights. We designed the arm to articulate so that different configurations each specialize in collecting one type of game piece. The intake jaws not only hold cargo in place, but also disengage hatch panels from the panel manipulator by pushing the panel into the rocket.
Our 2018 robot, Charlemagne, used a long arm to place power cubes into the high and low switches. Its intake could contour to the cubes, whether they be diagonally or regularly positioned in relation to the robot, in order to collect them more easily, reducing cycle time and maximizing scoring. It also had deployable ramps to lift other robots for the endgame.
Our 2017 robot, Alexandria, specialized in bringing gears to (station) with both a human player station receiver and gullwing outtake and a manipulable floor intake. It had room to store many balls to shoot, though we did not end up using it in matches. A rope climb was implemented for the endgame because it was fast and effective at lifting the robot off of the ground. The robot was very robust - it fell a few times, but never had any damage!
Our 2016 robot, Napoleon, was equipped with 6 large wheels on a West Coast Drive layout in addition to a sleek and compact design to effectively overcome the field defenses. The shooting system for the “boulders” consisted of a mecanum wheel intake which also served to manipulate field defenses, and a flywheel shooter with a pneumatic redeployable hood which stored away when moving under field defenses.
Our 2015 robot, Marie Antoinette, was the first one the team built from scratch. It utilized a claw which could close on both totes and cans, in addition to a winch style system which connected to the top of the tall superstructure to move the claw up and down, enabling high stacking to score points. We implemented a mecanum style drive because no direct defense could be played in this game, so the improved maneuverability did not come at the cost of being susceptible to defense.
2014 was our rookie year---it was also the first year of the high school, so the team consisted of only 9th graders! We used the kitbot chassis so we could get a moving drivetrain quickly and learn how to wire and program a robot. The team had ambitions of being able to catch the ball, and prototyped many ideas; unfortunately none of them worked, but we learned a ton! We focused on being able to intake the ball and pass it, to earn extra points, rather than shooting the ball.
