1/29/16 – Friday – Tapping Out

First things first, the team assembled around 3:10 to partake in the daily meeting where they’d get their goals and such. Today, the team would stay until 9:00 or later, and all members loved hearing this for it meant more time to work.

Jacob of Simulation worked with Dr. Stone in measuring the compression of the ball when in the intake. They then took measurements using weights on the two intake wheels to see how much it compresses at given weights. Jacob can take the data and find out how much force the motors would need to launch the balls with precision and accuracy.

Lathe member Lousaper has spent the past days working on the Lathe to finish parting the drive shafts. Now she was helped by Mr. Black to tap the drive axles. During so, they ended up breaking three separate taps. The first was due to operator error, but the next two was due to chip load and the depth of cut. Finally, they settled on a spiral point tap, finding it’s much stronger than a spiral flute tap. With it they were able to produce much better results in the 7075 aluminum axles and re-manufacture two axles after they’re scrapped (due to broken taps).

Mr. Black also installed hooks to hang Band Saw blades from in the Inventory Room, and one hook to hold C-clamps off of in the Drill Press Room.

As this day ran late, members ate marvelous pizza.

Alexander, our extraordinary Vice-President began the design of the actual robot shooting and intake mechanism. He has decided there will be two 775pro motors used in the shooter, one on top and one on bottom, having individual control of each. Each motor has a single stage of belt reduction at a ratio of 12:45, and maximum RPM is just under 5,000 theoretically. Alexander also made sure any parts CAD or CAM makes is made how it was designed, so he makes checks on manufactured parts.

The lab closed really late, or early depending on how you look at it at 2:05 AM. In less than seven hours, the lab will open again.

1/23/16 – Saturday – Expo Day and Mountain Ave. Science Fair

While Clark’s Expo Day didn’t start until 11:00, Team 696 members arrived at Clark in their team shirts and black slacks before 9:00 AM. Expo Day is very important for showing what type of high school Clark Magnet is to parents and prospective students. While there are many classes and courses that are open to visitors, Team 696’s lab is the main attraction to many. Clark’s Expo Day even made the news on LA Times!

Shortly after 9:00, Business member Andrea designed and printed out flyers to guide parents and students to the lab.

Prior to 11:00, team members helped position multiple robots from past competitions throughout the school. Two members would stand with each robot to explain to guests what Team 696 was and to answer any questions. If prompted, which was often, one member would also lead intrigued guests to our Robotic’s lab where other members were waiting to give a tour of the lab.

The lab was filled with excited parents being pulled forth by their children. With so much going on, many 696 members were available to explain what transpires in the lab to anyone that wished to know.

Sipan explained the Swerve Drive, a type of wheel mechanism designed and created by a past Team 696 member.

A very popular attraction was the driving of Snapdragon. Taking place right outside of the lab, people gathered around to watch our 2014 robot Snapdragon throw a ball and chase it down. Some lucky spectators were even able to participate in this event!

After Clark’s Expo Day came to an end, and all parents and students long headed back home, Team 696 members remained behind to clean up their school and the lab. At around 4:00, Mr. Hoard and four members loaded Snapdragon into his truck and drove over to Mountain Ave.’s Science Fair.

Team 696’s appearance at the Science Fair has been a long-kept tradition of the team and a favorite event with the children. Their joyful screams filled the air as they waited for the ball to get launched their way. They’d scramble to get it, then race to replace it back into Snapdragon.

The only thing the children loved more than catching the ball flung from Snapdragon was being able to actually drive it themselves. Team 696 member Daniel and Driver of Snapdragon explained to each student how to control the robot. Their faces could hardly contain their wide smiles.

A collective sigh spread around when it was time for Snapdragon and Team 696 to pack up and return to Clark. Promising to return the next year, Team 696 members loaded Snapdragon back in the truck and drove back to their lab.

During and between the Clark Expo and Mountain Ave.’s Science Fair, Team 696 members were hard at work as any workday.

Roupen of Welding advanced the prototyping shooting mechanism by adding encoders to each shaft. These will allow the team to get an accurate measurement of how fast the wheels are turning. Roupen then asked Programming member Daniel to write a program to remote-control the motors. They then began to wire the encoders using QHR as a base. Other Welding member Eden helped out CAM.

Andrea of Business has very nearly finished the button design for the team and Nicole completed the Logo section in the Brand Guide.

CNC Mill team was plenty busy as well throughout Expo Day, explaining the process of what they do with the Mill to visitors. Dustin also explained how the design of a CAD model gets transferred to the Mill and out comes a part. After Expo Day ended, both members Dustin and Nanor used the Mini Mill 2 in order to cut out parts that will be attached to the gearbox. They started by cutting out rectangles on the Plasma Cutter with help from CAM member Jonna, then put the parts into the Mll to drill it using Jonna’s CAM program. Together, the trio made over 10 parts.

Some other major accomplishments of the day include how the final drive base design was finished, and the frame will start to be manufactured tomorrow. Another big deal was how the wheel hub stock was cut out on the Horizontal Band Saw then put through the Lathe whilst the Mill portion was finalized in CAM.

Today, the lab closed at 10:30 PM.

1/21/16 – Thursday – I Believe I Can Fly

Lego Robotics members from Lincoln Elementary came to tour Team 696’s lab today. Arriving around 3:00, the students entered excitedly into the lab. They first listened to Mika talk about the team and what goes on in the lab, using Centurion as a focal talking point.

DSC_0010

After touring through the programming room, the students then filled the computer room where CAD and CAM teams usually worked. Here Mr. Black told them what goes on, showing them the two flat screen televisions overhead.

Mr. Black then led the Lincoln students into the work-floor, where the HAAS machines were. Amazed by the fantastic and large machinery, the Lincoln children were ecstatic to be able to partake in the operation of the powerful machines.

At last, the moment they all longed for was finally here. It was time to drive the robot. Lining up outside, Team 696 Vice-President Alexander worked one-on-one with each Lincoln student, showing them how to properly handle Snapdragon.

Feeling excited and trembling from happiness, the Lincoln students left Clark Magnet’s Robotics’ lab. Never before had they been so sure of what high school they wished to attend. From what they experienced today, all wished to attend Clark Magnet.

Following the Lab tour, the robotics meeting began. Starting off with a team meeting led by Mika and Alexander, members listened to what needed to be done for the rest of the day.

Shortly after this meeting, the individual sub-teams split apart like a bag of marbles being dropped off a table. Mika met with the members who would be working on everything prototype.

Over in the Cinema class one will find Jacob of Simulation team hard at work. For today he looked mainly into the motor as he needs to understand the motors of the flywheel launcher to properly understand how the battery level will affect the RPM of the wheels. And so Mr. Black let the Prototyping team know about a “closed loop encoder.” The closed loop encoder is something that takes the voltage of the robot into account when outputting the RPM, so the RPM doesn’t change along with the charge of the battery. They also discussed Euler equations.

Roupen of Welding team configured the flywheel prototype using different sized balls. Managing to shoot 25 balls and only 3 missing, Roupen, Leaders Mika and Alexander, CNC Mill member Nanor, and Programmer Meetkumar hand-fed balls into the shooter. They also tried adapting a piston feeding method but it didn’t bode well. The group plans to improve the design tomorrow.

Andrea of Business worked on the Stronghold Team button deigns using Adobe Illustrator. Besides learning how to setup and fix the Makerbots, she also helped Anna vinyl. Nicole spent the day determining the measurements and angles of Team 696’s logo for the Brand Guide. She used a team t-shirt as a reference point.

Prototype members Karin and Lauren measured the exact weights and diameters of all 6 new balls and the ball received in the Kit of Parts.

Bhavin of Programming team resolved issues the team was presented with when using GRIP. He also researched potential low-cost alternatives to the current cameras and ways to adapt it for the robot during competition. Fellow Programming members Jake and John worked on getting Snapdragon’s low-gear program working to use on Expo Day. They hope that by using the slow-mode people can see the motors and mechanisms in work.

Jonna and James of CAM worked on CAM for the entire day. James made a wheel hub adapter for the drive tires whilst Jonna made bracket to mount the gearbox on.

CNC Lathe member Lousaper went over a program for the new wheel hub and plans on using the Lathe for it soon.

CNC Mill member Dustin began building the bottom of the Castle Tower, but didn’t have enough wood to finish. He then helped Prototype member Devon on finding materials to complete the Castle Tower.

Animation team members Anthony C. and Christopher started working on the robot’s main animation. They’ve set up the render farm and began preparing for issues that might come up later.

1/14/16 – Thursday – Low Rider

Clark members Anna and Daniel went with Mr. Black to Roosevelt Middle School at 9:45. While there, they showed off Snapdragon in action to the students. Afterwards, Mr. Dall gave a wondrous presentation on why Clark Magnet High School is a good school to go to. The Clark students returned to school at 12.

Some members also traveled down to Lincoln Elementary School. Jonna, Lauren, Luke, and Samuel went with Maggy – a Clark student – to assist the Lincoln Lego Robotics in their tasks. Heading down a little after 2:20, the members returned at 4:00.

There was also a meeting this day, running from 3:00 to a little after 6:00. For a great majority of it, Mr. Black, Mr. Hoard, and Mika met with the Business team members Arvin, Anna, Nicole, and Andrea as well as with Photographer, Blogger, and member of Media, Samuel. The reason for this meeting was to discuss community outreach, award submissions, and the upcoming Expo Day schedule.

Prototype members Devon and Lauren worked with Meetkumar and Jake of Programming and with Jonna of CAM on the prototype robot. Together they measured the base for a 6 wheel drive train, all within an hour. They then tested the wheel placement and found the first and last wheel space must be closer to the ends of the robot. They also found that it is quite impossible to slowly drive over the obstacles, the robot needs to be moving fast. The faster the robot goes over the obstacles the easier ti is. The triangles they’ve attached to the front of the robot increasing air-time experiences as it slides over the obstacles.

Christopher of Animation finished the character modeling tutorials and designed a box and edge for a character to be modeled in. He began looking for a model to fill out the cage and for a hand and head tutorial to finish making the character. Anthony C. spent the day colouring the CADed field for the animation and removed hidden or irreverent parts from the model. He did this so it won’t slow down the rendering time for each scene.

Jonna of CAM also worked with Dustin and Nanor of CNC Mill. The trio built the Low Goal using the Router. They also started putting the Castle Tower together so it could stand on its own. Near the end, they split off to help Devon and Lauren of Prototype.

DSC_0331

After the Low Goal was cut out from the Router, Karin of Prototype and Lousaper of Lathe assembled it. Roupen brought out Alexander and Mikia and Anthony to see it, and they realized how difficult it would be to fit a high-goal shooter into a robot that can fit under it. They then found some neon pink and green fabric in the storage closet. The pair used the fabrics to make a flap on the Low Bar, Lousaper took it home to sew it.

The Clark Stronghold (lab) closed at 8:30.

1/13/16 – Wednesday – Toll Presentation and Optional Meeting

This day contained two events. One was a presentation down at Toll, and the other was an optional Robotics meeting.

Mika, Alexander, Jonna, and Anthony K. traveled to Toll Middle School at 9:45. Upon arriving, they helped get Snapdragon into the auditorium where Mr. Dall was going to present to the Wilson students.

Alexander, our assiduous Vice-President, worked with Mr. Widholm and Mr. Black on constructing a team calendar. He also worked on creating a “Robot Timeline” spreadsheet. This would be used to collect all of our official meeting dates and give us as a team insight for planning a time-frame in which parts would need to be designed and fabricated.

Mika, our prodigious President, focused on Trello and putting all the necessary tasks that must be accomplished in the upcoming days. She organized them so she had a clear vision of what goals must be achieved and when.

Anthony K. of CAD worked on the base design of the robot. He used QHR as a point of reference.

image4

Devon of Prototype team and James of CAM tested possible wheel configurations for the base of the robot. They did this to not only make sure the configuration of the wheels would work, but to find out if the actual wheels were made of the correct material that’d best suit the tasks at hand.

Mr. Black also informed the team of our brand new sponsor, AutoMeter. As a team, we hope this is the beginning of a very long partnership between them and us.

Team 696 Robotics’ Stronghold closed for the day around 8:30.

1/12/16 – Tuesday – Wilson Presentation

Clark students and Robotics members Samuel, Lauren, Anna, and Mika left Clark for Wilson Middle School at 1:55. Mr. Dall gave a very heart-warming speech, utilizing the Robotics members and their robot Snapdragon.
