Safety Meeting

This week, the team conducted their first safety meeting of the new robotics year, led by Safety Captain Cody Nee. The meeting addressed important safety precautions, such as proper attire when in the workspace, first aid precautions, battery maintenance, and how to use a fire extinguisher. Additionally, since students may be exposed to chemical and physical harm, it is important that team members are aware of the various substances that inhabit the robotics’ workspace.

The photo above is of room 91 at our first official team meeting Monday Sept 9th, where we started our 20th anniversary year. As you can see, desks and computer monitors that cannot be moved have been installed. This was done without warning or notice, and drastically limits any team build activities. For now, we make use of the space as we can, and are able to stay in the room. Space for us is being determined, and the district is committed to moving us somewhere where we can thrive.

At this time of year, we normally are working on our JPL invention challenge build and educating new team members how to safely use tools, and working on projects to better our skills, plus lots of fundraising. Regional FRC selection is also due next week.

Aerospace Valley Regional

On April 4-6, we competed in our second regional at Aerospace Valley in Lancaster. We ended up ranking 22 out of 37, but that does not really tell the true story. One of the reasons we were that low is that other teams saw us as a competent threat for cargo balls and played defense against us on several matches. That’s the kind of thing you usually only see for top ranked teams. We also helped shut out Code Orange on their first two matches (sorry guys, you have an awesome turret robot), and they were part of the winning final alliance. We were selected as a first choice pick by the 4th seeded alliance, won our first match and then lost the second two, in part because our alliance partners broke down. We were eliminated in the quarterfinals.

Something weird happened at AV; our pit crew was bored. There was nothing for them to do after practice day, the robot never broke. Wow, that’s amazing. Think we got the issues sorted out with all the hard work at Monterey. Speaking of which, at Monterey our robot frame was damaged and needed to be replaced. Our team completely disassembled the robot, swapped in the new frame and put everything back together and passed inspection by 2:30 on practice day. Again, wow, that’s impressive.

Wow, how on Earth did we get here? After a shocking victory in the inaugural Monterey Bay Regional, Team 702 won their place at FIRST Championships in Houston. No one expected us to do so well there, least of all us, but this win serves as a testament to the tenacity and commitment of the students from day one.

Build Season:

The season kicked off on January 5th with a trip to LA Tech High, where students spent time with other teams watching the reveal, brainstorming ideas and learning the rules. This year we intentionally slowed down the design phase, trying out all sorts of ideas with proof of concepts and prototyping. This year robots had to deliver cargo balls, deliver round hatch panels, and climb a platform, and after much deliberation the team decided to focus on the cargo and hatch. After a long 6 weeks full of late nights and tough builds, we had just barely built a practice robot and a frame for the competition robot. On bag night, the team stripped off all the motors, transmissions, electronics and wiring from the practice robot and quickly installed them on the competition bot. The robot was sealed with 3 seconds to spare, and we did not have time to turn it on or test it.

Post-Build:

Knowing the team had their work cut out for them, the time between bag day and competition became both a time to celebrate and time to kick into high gear. After an exhausting 6.5 week season, the team took some time to enjoy themselves with a great post-bag celebration at team member Zeke’s house. Numerous roadblocks meant we never got the practice bot working very well, and never had enough time to train or choose a drive team. Running out of time, we stripped down the practice bot for parts and packed up for Monterey Bay, knowing we had a lot to do before we could compete.

Monterey Bay:

This year we made a concerted effort not just to play the mechanical part of the competition, but to also work the social game. You cannot win a regional with just a good robot, you must also have partners and connections. Diana and the scouts went around numerous times talking with other teams (pit scouting) as well as scouting the matches to see what other teams were doing and how well their team and robots performed. Our team was invited to a game night on practice night, where the team had a great time and got to know the other teams. It turns out that every team who attended that game night made it to championships, and that is where the team that picked us for the playoffs learned about us. Additionally, we made strong relationships with Bay Area teams, and have been invited to numerous scrimmages and workshops as well.

The competition began Friday with a practice day. Our build team did an amazing job getting the robot deconstructed and reconstructed, passing inspection by 2:30 pm. We got out on the field 3 times to practice, and the robot broke very time. Our biggest problem was the arm cable kept breaking, so a fast trip to Home Depot for a stronger cable was made. We went into our first real match not knowing if the cable would hold or not. Thankfully, the cable held and the robot worked beautifully throughout the first day. The only issue that came up was a loose wire after coming off the initial platform, which disabled the robot for two matches but ended up being an easy fix. All was well until the end of the first day, when the last arm belt snapped. No spares were left, and after a mad dash to every auto shop in town, no replacements were found. On our final day, we started with a frayed belt and a prayer. Despite these setbacks, we were the top or nearly top team for handling cargo balls, a testament to our great design and drive team.

We finished qualifying rounds in 22nd place, but 3rd for cargo scoring. To win, alliances needed a robot that could climb, place cargo balls, and place hatches. We dwarfed the competition with our speed and consistency in cargo balls and defensive play, so we were picked to be on the 3rd place alliance. We are so happy that team 1671 picked us, and we won every single match we were in. We were undefeated in the quarterfinals, semifinals and the one match we played in the finals before we were taken out. In the semifinals, we defeated the second-place alliance, but in the last semifinal match our team member accidentally hit us and broke off our arm. We still won, but could not fix the arm in time for the next match. So we took it off and played strictly defense. Without a cargo scorer or any way to score points, our robot played a purely defensive game and still beat out the first ranked alliance. Wow. Then our drivetrain died inexplicably, and after many minutes of frantic work and help from many teams and the competition personnel, nothing more could be done. The team’s main driver Taylor made the right and most graciously professional call to ask the alliance leader to take us out and substitute in another team. Pandemonium ensued as backup teams were hard to find, and the other alliance was forced to sub in another robot as well. They tried to pick the same team as us, and Team 6059 changed the color of their bumpers nearly four times! The volunteers even had to put in a call to FIRST headquarters to ask them what to do, with the whole regional wondering what was going to happen next. Eventually the alliance subbed in Team 2643, who had a driver who had never driven defense before. We lost the next round, as the new driver didn’t know how to use the robot and was not good at defense. So now we were down to wire, with only a tiebreaker match left to play. Taylor had to run alongside the new driver as they ran out to the field, coaching them on how to play defense at all. The match went down to the wire, so close we were not sure until the final score came up, but it came up in our favor. It was an incredibly close match, but we won the regional (all teams on the alliance win even if swapped out)! Not only did we win, we won on merit. We won because we performed well, we won because we built and drove well, because we played the social game, and because we earned it.

What Now?

Now that the team has secured a position at the World Championships in Houston, we have to focus on fundraising and allowing a larger demographic of students to go. Two years ago, the last time the team competed in championships, only one sophomore, a few juniors, and a number of seniors were able to participate in this life changing experience. Taylor, the Systems Engineer of the team, is that sophomore and he is the only team member left that has experienced attending championships. His knowledge of the competition allowed us to be successful for this year, but he is a current graduating senior. We need future leaders to attend championships so that they can have that background in logistics and the competition and so that this team can continue to grow into the future. However, the team is very limited due to our lack of funding. We need support from team members, parents, and local businesses in order to send as many students as we possibly can to championships. With the competition starting in less than a month, and other regional winners in a hurry to purchase flight tickets and hotels, we are in great need of financial support. We are asking for donations which will be used to cover the financial costs of student’s transportation needs, as well as to ensure the team will be able to function during next year’s build season. Any and all donations will be greatly appreciated! The team as a whole has made history for both the school and our team, and with your assistance  we can continue to grow our legacy.

Please help our team realize this dream. Thank you!

Build Season Week 4

With less than 17 days to complete the robot, the team has been working diligently to finish the project. So far the students have designed and prototyped  the cargo (ball) and hatch mechanism, the elevator, and an arm for the robot. With the competition closing in, all subteams must be at their very best in order to the build to be successful.

Subteam Activities

MECHANICS– has been creating the parts of the robot as well as tweaking the design. As we start week #5, they are cutting and assembling the final competition parts.

CAD– has been creating digital 3D models of the mechanisms as well as measuring the pieces being built and documenting any change. The CAD team has also drawn and provided blueprint schematics for all the field pieces and has also designed and built a prototype battery cart.

DRIVE TRAIN– has been finishing up build of the field pieces, cutting parts for the new drive base and assembling the transmissions and wheels.

PUBLICITY– continues to work on their Chairmans essay and their presentation

PROGRAMMING/ELECTRONICS– has been both learning and creating the robot’s code, testing sensors and making sure their motor control software and controls are working.

SCOUTING– have been preparing the Scouting Test, as well has their own presentations

After bag night on Tuesday Feb 19th, the build season will continue through March 20th, but at a less frantic pace. The team will be building a second robot to practice driving and control automation. During this time, we will meet a little less frequently and not as late.

Scouting Test

One major responsibility of the scouting subteam is the creation of the Scouting Test. The Scouting Test includes a variety of questions regarding the FRC game manual for this year’s competition. Anyone wanting to be on the drive team and the scouting subteam must pass the test. For drive team members, the passage of the written test means that they can move on to a driving test, and then practice to be ready to drive the robot at competition. For scouting, passing the test means that the individual can become a scout for the competition. At competition, the purpose of a scout is to take note of the other teams and their strategies, which means they have to be familiar in the aspects of all the subteams; programming, mechanics, drive train, CAD, and publicity. The team as a whole will be preparing for the test, so if you would like to review the FRC game manual you can view it HERE

Competition and Attendance

As the build season comes to a swift end, it becomes time for the team to prepare for the actual competition. For the first competition at Monterey, only the drive team, scouts and some of the team leadership can attend due to limited space in cars, hotel rooms and costs. For the second Aerospace Valley competition, we will be driving there each day and everyone is welcome to attend. Prior to competition, the drive team, scouts and anyone interested will be visiting the Orange County Regional competition on Saturday March 2nd, where we will be observing and learning what to expect. .

Here are the dates:

  • End of Build party, Saturday Feb 23rd, 5 pm
  • OC Regional field trip, Saturday March 2nd
  • Virgin Orbit field trip, Saturday March 9th
  • Competition #1; Monterey CA, March 21-25
  • Competition #2; Aerospace Valley, April 3-6

After weeks of working, the competition serves as a chance for students to see the fruits of their labor, so we hope all of those interested can attend.

Thank you!

Build Season Week 2 and 3

During the second and third weeks of build season much has been accomplished. The team has been building the practice robot as well as field pieces. All sub teams have being working with each other to create a robot that the team will be proud to bring to the competition.

Subteam Contributions

  • Mechanics and Drive Team have been working together to build the practice robot.
    • Has constructed the elevator and frame, working on arm for added height.
    • Also has developed the mechanism for the ball launcher and the hatch grabber
  • CAD has been busy drawing
    • 3D printing model game pieces to replicate the competition field.
    • Modeling alliance station, hab levels, rockets and cargo holds, creating blueprints for building these field pieces out of wood.
  • Publicity has been working on their Chairman’s essay.
    • This gives the team an opportunity to win a free ride to the competition
    • Also required by our funding sources
  • Programming has been learning how to program the components of a robot such as the joystick and controller.
    • Have been learning how about subsystems and commands, to program the controllers for the robot

Study Hall

Monday through Thursday the robotics team has a 45-60 minute study hall for students to do their homework and study. It is important that students use this time wisely, since they will be continuously working for the remainder of the club meeting. Hence, if students do not have any homework, they are asked to remain quiet during the study hall, so they won’t disturb other students. Thanks to Robert W chatting with his physics teacher Dan Carter, and the principal providing a room key, the robotics team now has access to a chromebook cart every day, allowing students to complete any homework they might have that requires a computer. As these computers do not belong to the team, students are asked to return them before the end of the day, and obviously not to mistreat them.  


Donations

The robotics team is very lucky to have many generous parents who have been donating dinners and snacks for the students during the long build season. As the team stays daily to 9:00 PM these meals are a huge help, as they keep the students energized and well fed. We also appreciate the financial donations made by several families, and Clinton Goldsmith for running to the hardware and metal stores to transport and sometimes buy our materials. So thank you parents for your wonderful donations, the robotics team truly does appreciate it!

The Season Begins

This past weekend, the robotics team held their annual launch party. For the first time in team history, students went to High Tec LA, to learn about the build season’s theme, goals, rules, and how the round was divided. They were able to discuss with students from different schools about what the team’s goals were for the robot, what they wanted the robot to do, and what was the primary objective for each part of the round. Once they returned to the CCHS campus, the team members involved shared the generalization of the task, and discussed the team’s personal goals for the robot.

Workshops and Team Commitment

The robotics build season requires a lot of the students. Team members are expected to be focused on the build until the season is over, giving it priority over other non-academic matters. The build season also requires a great deal of time, since the team is expected to stay working until about 9. Therefore, the team ask for the help of parents to provide dinner for the team during the season however, it seems that there are enough members, that some families might be able to work together.

As all subteams are involved in the creation of the robot, it is important that every member of the team does their part. So, it is the responsibility of the team leaders to make every member be useful and up to date. Subteam leaders communicate with their team through the Slack app, which is very useful when communicating with large groups and every student in robotics is required to be part of the app.

2019 FRC Deep Space Game

This year’s competition is a spaced theme game. Alliances of three teams compete to place hatches and load cargo onto the bays of cargo ships and rocket. The total length of the match is 2 minutes and 30 seconds.  Each match starts with a “sandstorm” which is a period of 15 seconds in which the driver’s visibility is limited and robots must either operate on autonomous mechanisms, or drivers may be able to see through cameras, if the robot has any. After the “sandstorm” has cleared drivers will take control of the robots and will work to earn points for their alliances. An alliance can score points by placing cargo or placing hatches on either the cargo ship or rocket ship to prevent cargo from spilling out. In addition points can be gained by going up various platform levels at the end game.In order for an alliance to advance, thy must win rank points, which is awarded to those who win matches and completely stock their rocket ships with cargo. The team is working to build a robot that will be able to complete these tasks, as well as hoping to allow us to succeed at our regionals.

Week 1 Activities

The team worked on various ideas for the hatch, cargo (ball) and climb options. They began by using simple designs and methods (see photos below) to determine proof of concept. When things looked promising, they then started working on some simple prototype systems to further explore their ideas. By the end of the week, the team began discussing the pros and cons of each idea, and plan to decide the robot design to build during week 2.

Stay Tuned!
