Kamehameha, Steamworks 2017
- Kamehameha uses an active gear mechanism that intakes gears from the human loading zone and delivers them to the airship.
- Debuting at the Las Vegas Regional, Kamehameha can also make use of a newly added ground intake on the opposite side of the robot.
- Kamehameha can intake fuel from the hoppers and feeds the fuel into a double flywheel shooter that ai ms for the high-efficiency boiler.
- Our 6-wheel pneumatic West Coast Drive allows for a sturdy and reliable drive system.
Kamehameha is our robot for the 2017 game, FIRST Steamworks. As per team tradition, members submitted names, and we voted on them during a Saturday build season lunch. Our robot is named after King Kamehameha, who was the first ruler to unite all of the Hawaiian islands under a common leadership. We chose this name because, as our team has grown, we have made it our mission to integrate and unite all of our students together into a team that has become a family.
Our design process for Kamehameha consisted of:
- Deliberating on priorities for robot tasks on Kickoff day — climbing and gear handling were prioritized, followed by high goal shooting
- Proposing mechanisms to achieve these goals and then prototyping them
- CADing these designs to mock up the final robot before we’re able to build it
- Assembling the robot using the CAD files we created
- Testing and tuning the complete robot and its identical practice robot
Orion, Stronghold 2016
Our 2016 robot, Orion, derives its name from the constellation with its iconic belt. Orion was presented with the design challenge of being able to fit under the low bar; to accomodate this, its single fly wheel shooter has the ability to fold down into the base of the robot. To traverse the obstacles that Stronghold provides, such as the rock wall, rough terrain, and moat, Orion drives with a tank drive. Orion’s boulder intake mechanism uses a set of rollers that funnel the boulder towards a teeter-totter, where it rests until shooted with the single fly wheel or ejected back out through the intake. Because it has to accomodate twelve speed while still leaving room for the boulder to rest and shoot, Orion’s electronics panel is U-shaped. Orion’s frame is made up of 90 wall aluminum powdercoated yellow. Our sponsorship panel locks on to the top of the robot and is detachable for best access to the electronics panel. This panel is made up of our signature carbon fiber, which we have used on every robot since our 2011 build season. Despite its stout stature, carbon fiber panel, and thoughtfully built frame, Orion nearly ran over the weight limit of 120 lbs. Orion’s autonomous allows it to cross through the low bar, in addition to the B and D category defenses. Its lidar and vision processing allow it to shoot through the high goal.
Valkyrie, Recycle Rush 2015
Valkyrie, named after a mythological Norse winged creature, is able to manipulate totes and recycling containers. Valkyrie has a welded drive base and “strongback”, welded by students on our team. The drive bases and the “strongback” were also carboned in our shop by students with guidance from some of our mentors. Our “strongback” is coded to automatically tilt to keep the totes parallel to the ground when we intake them. We have “clappers” with intake wheels to help us take totes into the belly of the robot. Our carbon “claw” can pick up containers while making stacks of totes underneath. We decided use an H-drive with omni wheels as our drivetrain, allowing us to drive sideways. Our center wheel in pneumatically suspended giving a constant pressure on the floor while allowing us to drive over the center bump easily. The software on our robot continues to improve each year. This year we have two IMUs (Roll and Yaw), allowing us to measure of of two access points. The first, mounted sideways, measuring the angle at which or strongback is, and the second measures if we are straight.
Odin, Aerial Assist 2014
Named after the head of the Norse gods, Odin featured a powerful shooter and a fast drive train. It accomplished the goal of passing the ball over a center truss to a human player for extra points. Odin made it to Championships in Saint Louis after winning the regional in Las Vegas. Not only was this the first year that we built a second robot for driver practice, but it was also the first year that our team had a mascot.
Sun Tzu, Ultimate Ascent 2013
Sun Tzu shot frisbees at approximately 40 miles per hour and could complete a ten point climb to finish the match. Equipped with a California Drive and our trademark molded carbon fiber, Sun Tzu brought our team to Championships in St. Louis for the first time. Sun also had a Kinect sensor used to track targets more effectively than normal cameras, and a functioning thirty point climb that was never implemented in competition.
Yaroslav the Wise, Rebound Rumble 2012
Yaroslav fired basketballs into hoops using a catapult and finished the match by balancing on a bridge. It’s catapult shooting mechanism was unique among its competition. it was also built with a custom gearbox and a camera on the very top in order to detect the hoops. Yaroslav faced off against our school mascot in a basketball shooting competition.
Ivan IV, Logo Motion 2011
Ivan picked up inflated tubes using a claw on a vertically extendable shaft. We custom built Ivan’s mecanum wheels to allow for strafing across the field. At the end of the match, we would release a smaller robot named Feodor which would climb up a metal pole as quickly as possible. Ivan was our first robot that incorporated carbon fiber, a material that has since been incorporated into all of our new robots.
Cixi, Breakaway 2010
Cixi used two different air based mechanisms in 2010. It used a vacuum to capture balls and used pneumatics to shoot the balls into the goals. Cixi was named after the Empress Dowager Cixi, and it’s official theme song is “Don’t Stop Believing” by Journey.
Auto Von Bismarck, Lunacy 2009
Named after the Warlord Otto Von Bismarck, Auto collected balls off of the floor then shot them through a moving target or dumped them into a trailer. Auto was originally overweight and in order to fix this problem, the team drilled holes into the panels, giving it an appearance similar to swiss cheese.
Xerxes, Overdrive 2008
Xerxes was a lap running robot; it would move around the course in order to score points. It was a very simple robot because it did not have many functions. Xerxes originally had a bar on it’s front in order to herd balls, but this broke during our first match.
