Post Build Season

This year’s build season has ended, but that doesn’t mean that the Robotics team is no longer working. The team still will meet weekly on Mondays and Wednesdays until 6:00 pm, and on Saturdays between 12:00-6:00 pm.

Bag Night and Celebration

The Robotics team bagged the competition robot Tuesday night, Feb 19, which will not be unbagged until the Monterey regional. After 6 weeks of hard work it was clear that the team deserved a celebration. Thankfully team member Zeke, agreed to host a party at his house, and it was a huge success.

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!

Prototyping a cargo collector (ball) mechanism

Week 1 begins

Build season has begun! The team participated in the kickoff event with Team 4 at LA High Tech High School on Jan 5th, and we had a great brainstorming session for several hours with them. Here at CCHS, we had a kickoff party where the team, parents and mentors all got to see what challenges we face this year.

This week we have been discussing pros and cons of several design options. Tuesday we drew out half a playing field outside to get a firsthand look at the field. We drove the old robot around, had humans be robots and field pieces. From that, we learned a lot about what is possible, how long things might take, how fast the robot might need to be and various strategies we want to consider. From there, the team started making prototype devices to manipulate the cargo and hatches. Lots of discussion and fun, and some good ideas are coming out of this work. We are now exploring more options and building more complex prototypes, incluinding an idea for making the robot jump.

More to come…

Robotics Team Agenda

Finishing Up Pre-Season Projects

CAD’s New Table:

Recently the CAD subteam has been designing a new table. The current set up is three desks placed side by side, which is not ideal. With this new L-shaped table design, the team hopes to provide more leg room for students working with the computers. It will also provide adaptable space for all computers along with the team’s new printer. The design started with CAD drawings that had accurate measurements and detailed drawings of all components, progressed to design reviews and modifications, and the team ultimately started construction. Right now the table is nearly complete, with final assembly and a laminate top to be completed before Kickoff. Both the CAD and Programming subteams are eager to see this table completed.

 

Team Merch:

The official team shirt is here! This week the team received the new shirts for the year. For $40 team members can purchase a customized mechanics shirt. This allows the team to look professional and unified when attending competitions. If the price of the shirt is a concern, talk to either Dr. Stout or one of the team captains to figure something out. Hooray! New shirts!

 

Workshops:

This week was the first week the new members became official Bagel Bytes. Congratulations everyone! The members were divided into their respective subteams and began subteam specific workshops.

  • Programming discussed different types of loops and variables used in code.
  • CAD members worked together to grasp a better understanding of their software, helped the Mechanics subteam plan out their practice robot, and starting printing out various items with the new 3D printer.
  • Mechanics began building their first practice robot.
  • Drive Train has been helping with the table project as well as making new stools for the room.
  • Publicity worked on raising money for this upcoming build season and competitions.

 

Mechanics Workshops Demo Robot:

The Mechanics subteam is creating a new demonstration robot to replace the disassembled frisbee shooter. This new robot design launches wiffle balls, and is built for young kids to play with at elementary school science fairs. The team also has plans to build a ball collector and add an aiming device. Recently the team has created a prototype and is now starting to critique/change minor mistakes.

Launch Party:

As the preseason ends, the new build season begins! The team will kick off build season with a team launch party. Here both students and parents are invited to the robotics room to learn about the future build season and start work on our robot. They will learn about the task the team’s robot will be expected to perform, what each subteam is responsible for, as well as what is to be expected from both the students and their parents. The launch party is a potluck so please bring something to share and come hungry, there will be plenty of delicious food. Parents, please respond on SignUpGenius about the potluck and team dinners. The launch party will take place towards the end of winter break on Saturday January 5 @ 1:00 PM – Don’t be late!

JPL Projects

 

For the past several weeks, the team has been working on a project for the JPL foundation. The task is seemingly simple, to lift a pipe so that it stands upright. Although it appears simple, our students have to carefully program and design their devices, so that they may be effective. Students from both the MESA and robotics clubs have organized themselves into three teams of nine people. The students were able to plan out their designs using the available CAD software, and managed to create a multitude of functional and creative designs.Some relied on physics, others on pure mechanisms, making the various devices a site to behold. The JPL project provides students with a way to exercise their skills, and work together on a project with others, to get a sense of what it would be like to practice their skills at a professional level. Requiring the skills of members of each sub-teams such as mechanics, programming, CAD, and drive team, these devices embody what it means to be a team player, and are a great way for students to get to know their teammates and to polish their skills. This competition ended recently and we are very proud of the hard work of both the MESA and our robotics students.

Pre-Season Projects

Aside from the JPL projects, other members of the team have also been working on some side preseason projects. Through these projects, both the new and returning members are given a chance to interact with one another and get to know their teammates. In addition, the new members have the opportunity to become exposed to work tools that the team will be working with throughout the season, brainstorm design ideas, familiarize themselves with the workload that will be upon them during build season, and the most important part, have fun!

 

Here are some of the current projects the team has been working on:

 

Phone Charging Stations

Shown above is the progress of the phone charging station.

The members have first researched and brainstormed ideas and then finally began the design process through CAD. Afterwards, they slowly began the construction, which as you can see has been coming along nicely. The team is hoping to use to charger station to hold the charging phones when we are staying late nights and so that they will be able to communicate with their parents.

CAD Designs a New Computer Table

Currently the robotics team has access to 3 computers, all of which are place on 3 separate desk tables. Since these desk were not built to accommodate 4 computers, with their routers, keyboards, and the multiple bodies of students, it was obvious that the setup needed to be changed. So the CAD team decided to take charge, and designed a new table more suited for the task. The sub team divided into groups, filled with both new and returning members, and each designed a new table to replace the old one.  Additionally, the students were given a strict deadline, similar to one in the real world in that it simply could not be pushed back. Thus, the team members had to practice time management and teamwork skills in order to complete their table designs on time, and be ready to present. Presentations were given from each of the teams, and they were expected to list the aspects of their design that made it unique, as well as functional. They were also asked to share the faults in their design as well as the amount of material it would take to built it. Then, they were all given feedback from an experience returning member, and sent to adjust their design in hopes of lessening the faults. Once again, they presented their designs, and a winner was chosen! The chosen table design included means of support, allowed for suitable amounts of leg room, and most importantly provided room for all the computers. Although the team was announced as the winners, their design was not perfect, as most things never are. Consequently the winning team was sent back again to tweak their design. Once finished, all the students involved in the project began to gather the materials for the table, which is currently being built.

Battery Cart

Another project the team is working on is the creation of a new cart to place the batteries of the robot. The previous cart was too wide and hardly able to move through a doorway. Hence, the team is seeking to create a new one, so that the transportation of the batteries is more efficient. New students were tasked with creating the new design, carefully measuring the old cart and adjusting it to be more mobile. Since the batteries are rather large and heavy, the cart needs to have a great deal of support, and the students need to keep the weight of all the tools which are also going to be place on the cart as well.  With the help of returning members, they have already come up with a complete design and putting the final touches on the measurements.

Team Merch:

This year, the robotics team is looking to purchase new team shirts and hoodies in anticipation of the two competition we will be attending. Looking to buy mechanics shirts, and possibly hoodies, these items will make the team look more professional when going to competitions, as well as make the team distinguishable in the sea of other teams. However, these mechanics shirts are anything but cheap, and with so many new members the price to buy them is sure to be high. Although the mechanics shirts are rather expensive, they are going to be customized, with the team name and logo on the front and back. Aside from the mechanics shirts, the team is planning to also buy several hoodies for the team, so when it gets colder the team will still appear unified. Since in previous years, students had to cover their team shirts due to the freezing cold competition spaces,making the team look less professional. In order to prevent this from occurring this year, students will be asked to wear their team gear on the outside layer of their clothing, either as a shirt or hoodie.
