It was the big day! The moment everyone was waiting for. Bag Day had finally arrived, the day where – at midnight – the team would have to put their Robot into a bag until Competition.
Needless to say, everyone was pretty excited. After the briefing meeting, members split off to finish their assigned tasks.
Lousaper made some spacers for the Winch and Telescoping Arms on the CNC Lathe. She then helped clean the drive field in the cafetorium.
Programming members Bhavin and Daniel worked on getting the code ready to test on the Competition Robot. Other members Jake and John helped set up the drive field. Jake also ran some battery tests.
James of CAM finished the Operator Control Panel. The entire creation of it, from CAD to the countersinks were all him.
Business team member Nicole finished the black and pink t-shirt designs and the rough draft of the Business Plan Design.
For dinner the team got chili. It was quite good.
Andrea ordered buttons and helped Arvin and Anna with putting vinyl on the suburban.
Karin of Prototype team helped Mr. Larson with cutting and bending the polycarbonate that will become the sponsor panels.
Mr. Black spent some time to review the t-shirt design then order quantities. He then polished the driver’s side of the Suburban to help the Business team apply the vinyl logos. After this, Mr. Black helped get the Competition as ready as the team could before bagging it.
With only a few days left until Build End, every second wasted was a failure. But Team 696 still held a meeting before getting to work. It was a Friday, but school ended around 1:00 as it was a minimum day for the students. This meant Team 696 could meet for longer.
Jacob of Simulation team worked on the documentation. This covered static friction, shooter geometry, ball trajectory, drag, video verification of ball trajectory, calculating trajectory, and cleanup on the formatting. Team 696 is certainly glad we have Jacob as a member.
The wonderful Lathe team, consisting of member Lousaper, kept working on Delrin spacers. These would be formatted to the Telescoping Arm. Lousaper also worked on the spoil syncro bar and omni-wheel shaft.
Dustin, a member of CNC Mill team, remade two of the Spring Plates for the Telescoping Arm because two had snapped. The process took about 5 hours, he used the Super Mini Mill 2.
For dinner, as the meeting ran over 6:00 PM, was brought in. It consisted of fantastic chicken, pita bread and hummus, green beans, and a home-made potato dish.
Business team member Arvin finalized the textual components of the formal Business Plan. He was assisted in doing so by Anna. Andrea helped set up the gym for practice drive runs with the robot. She also finished the button designs on Adobe Illustrator and continued the Alumni book cover.
Daniel of Programming helped set up the gym field, then he worked on getting the Robot Arm to move and shoot balls. Bhavin, Jake, and John helped with field work.
Bhavin also worked on fixing some code.
Mr. Hoard, the Business team’s mentor and local “Super Genius” as he’s called, saved the day once again. The Telescoping Arms were sticking together, so the Extravagant Mr. Hoard designed and manufactured a prototype of the “hats.”
Mr. Black sent in the request for buses for our regional competition trips, made a lunch reservation for the Ventura trip, worked on building an ordering list for equipment and supplies for the lab, and machined snap ring grooves in the omni-wheel axles for the robot’s claw.
As usual, the team held a meeting before going to their tasks. At this meeting, they were told what to do for the day, and congratulated on their hard-working efforts for the past few weeks.
CNC Mill member Dustin began Milling the bar-stock for the three sizes of Arm Extension mechanisms. All six completed, two being 0.75″ and some 1.5″, during this Nanor and CAM member Jonna modified the black sprockets as some new holes needed to be drilled.
Lousaper, the team’s CNC Lathe team member, started making the pivot and winch gearbox shafts. Lots of progress was made this day.
James of CAM designed a Lathe operation for the very first time. Even he, an aged member of Team 696 still learns new things on a daily basis on the operations of the lab. The part James was designing will be a spool to be cut out on the Haas CNC Lathe.
Andrea of Business team finished vectoring dog tags for mentors. She had been using Adobe Illustrator, and now she continued to design the Alumni Book.
Programming team member Daniel was able to get the 2016 Robot to drive after much work. John watched Daniel throughout this process to fully understand how to program the Robot. Jake continued working with the team’s batteries.
Web member Luke continued writing up the Chairman’s Video script. He was helped by the beautiful and amazing Blogger and Photographer Samuel. They were also assisted by Clark student Maggy.
Mr. Black and Mr. Widholm continued their learning of the Haas ST-10 CNC Lathe. Today they attempted making the Arm Pivot Tube with very nice results. While they’re still running the machine manually, they hope to have it run an automatic program tomorrow. Mr. Black also took some parts to the Team’s anodizing sponsor and picked up rivets for the Frame Skidplates.
As the team would be staying late, pizza was brought and fed to the members. We were very happy and joyous for this event.
Also, the 2016 Robot has made its first steps! That’s right, the practice bot is now able to drive wired – a very big achievement and notable milestone in this Build Season.
School at Clark Magnet ends at 3:00, but by 3:10, those in Robotics meet in the lab to begin working. They all first attend a meeting that tells them what they should focus on for the day.
Member Luke of Web team worked alongside Clark student Maggy. Together, the pair worked on the script for the Chairman’s Video. Hopefully, this will be completed soon so the actual editing can begin.
Business team member Andrea worked on Excel, adding new sponsors to the sponsor list. She also worked on the dog tags with Adobe Illustrator, and is glad to report some of the dog tag designs are completed. Nicole remade the PDF of Behind the Design page featuring Team 696 for Mr. Black, then she continued working on the Team’s Brand Guide.
James of CAM finished the standoff program. At around 9:00 PM the standoff was beginning to be manufactured. James then began working on another standoff, but this one looks a little different.
Karin of Prototype worked with Mika for the whole day. Together they began wiring the Practice Robot. To do so, Karin had to learn all about the wiring process, then they had to actually physically wire it up.
Right before dinner, the Team had a Noodle War where they used Pool Noodles as their weapons. It was fierce and very fun.
Dinner consisted of delicious pizza.
Eden and Roupen of Welding finished the bumper brackets. They continued to weld the base plate onto the frame, finishing that as well. Good job Welding team.
Simulation member Jacob and Dr. Stone – his mentor – were concerned that the torque of the motors would end up stalling out, so they looked through their calculations. They found that when the ball is being shot out it doesn’t stall the motor at all. During the 1/240th of a second that the ball is in contact with the wheels, Jacob and Dr. Stone calculated it would reduce the RPM by about 200. After talking with Alexander, they now have to find calculations about a back axle in the shooter that would add some mass and act as a flywheel. A flywheel, not to be confused with a shooter wheel, is a wheel that’s specifically made to add inertia to a system. This would make the reduce in RPM less, increasing the torque of the shooter itself and decrease strain on the battery.
Mr. Black assembled the Kreg stand for Arbor press. He also fabricated a wooden top and organized the machinist toolbox.
Alexander, our Fantastical Vice-President, finalized the Pivot Gearbox. It will utilize two 775pro motors at almost 280:1 reduction to rotate the entire Robot Arm.
Continued wiring of the robot continued while Alexander finished the Competition Robot design. He also found a way to mount the sprocket for the arm joint to the box-tube and how to get the arm to pivot on a strong joint that won’t break.
The day had just begun, it was 9:00 AM, and members stood idly by in the lab. Itching to get to work, they first attended the meeting.
It was during this that Nanor, rookie and CNC Mill member, received the Platinum Wrench Award (formerly Golden Wrench Award) for her outstanding work on the Router.
Simulation member Jacob finally rooted out the last of his numerical errors, and now his calculations match up to about how they are in real-world scenarios. With this done, he entered the numbers into MATLAB as a polynomial equation. They used this to figure out other output numbers so there’s no need to make individual measurements anymore. After this, Jacob took more measurements to find the coefficient of friction of launching the ball from the shooting mechanism.
Lousaper of Lathe team made gearbox standoffs on the Lathe.
Programming member Daniel worked on the Drive Base and the code that will keep the motors from damaging themselves while stalling. Jake worked with Mr. Black to wire the batteries and he worked on a fully tele-operated control of Snapdragon. John worked on a code that should make Snapdragon move a given number of feet autonomously.
Arvin of the Business team continued his work on the Woodie Flowers Submission as well as the Chairman’s Award questions. Nicole, fellow Business member, worked on the Brand Guide.
Around 12:00, lunch was brought out. For today the team ate delicious hamburgers, freshly made. It was so good.
CNC Mill member Nanor won the Platinum-Wrench Award, then Routed out the second Base Plate with James of CAM. During this, Dustin and Mr. Widholm worked on the Side Rails. The CAM program had a minor flaw in it, and it messed up two of the parts before they restarted with two new pieces. After this, Mr. Widholm helped Dustin start the Cross Rails for the front and back of the robot. They pocketed one side of the rails with triangles and drilled the other sides, breaking an end Mill in the process. Reason being was the spindle speed for one pocket was 1/10th the speed of what it should’ve been.
Animation team member Anthony C. spent the day testing both rendering methods, making identical stills with each. He also made a CAD room inquiry and I Ray rendering is favored over Mental Ray. Christopher looked for materials for their secret project.
Welding team mainly waited for parts to be machined for them to weld afterwards. So Eden helped construct more Castle Tower sides while Roupen filed down the electronics plate to reduce the chance of cuts due to burrs. The team received a new shipment of filler rods, but they were covered in some kind of black tar, so Mr. Black called McMaster and a new shipment is being sent out to us.
Mika, our Consecrated President was busy with cutting and sanding and filing really complex parts. After the Router had its way with the Base Plate, Mika took it and sanded down the edges so it wouldn’t be as sharp and dangerous to users holding it.
She also was assisted by Karin of Prototyping team in tapping the holes in the Base Plate.
Alexander, our Sanctified Vice-President has over-watched the finalization of the shooting design as it was sent to the CAM team. He has calculated that the entire shooter/claw mechanism should be under 10 lbs. By the end of the work-day, the team has a solid idea of what the entire robot will look like, and it looks good. Alexander and Mika plan to order every needed bolt from McMaster by tomorrow, as well as another VexPro order and B&B Manufacturing and others. Mika, Karin, and Alexander worked on assembling one side of the drive train to see what the belt tension will be. They’ve determined that they’ll need a custom tensioner that is spring loaded form the findings. Alexander has also been working with the Programming team to ensure there’s room to place all needed sensors on the robot and said room is already in the designed robot. Work in CAD on the telescoping arms has been done, and the design for the primary arm structure is in work as well.
Mr. Black picked up some aluminum from Industrial Metal Supply in Sun Valley for the team. He also reviewed the Google Grant application that Arvin and Anna in Business room had completed. Mr. Black worked with Lousaper on the Lathe to produce tapped standoffs and with Jake and Karin to manufacture battery cables. At one point, he witnessed both HAAS Mills and Tormach Lathe running at the same time, a milestone to how far members have become at operating these machines properly.
As it was a minimum day, Team 696 met at the lab at 1:00 ready to work until 9:00 the earliest. Of course, Mr. Black, Mika, and Alexander began the work-day off with a meeting. The main purpose of today’s meeting was to prepare the members for all the guests the lab would receive on Expo Day.
To fully prepare the members to answer parents’ questions, the team performed small skits where one person would be the Team 696 member and the other a parent attending the Expo. It was very humorous indeed, but really taught the members how to properly act in that situation.
During the meeting, Luke of Web showed everyone how to use the email sign-up website. He had created it for parents to put in their email and sign-up for Team 696 Robotics’ mail list easily and quickly.
Simulation team member Jacob spent the rest of the day gathering parameters that he’ll need for future calculations. As the ball is going to be compressed in the flywheel mechanism, Jacob got some weights and placed them on top of the ball to see how much it’s compressed depending on the weights.
Over on Welding, Eden improved Obstacles and also cleaned up the lab for Expo Day. Member Roupen attached a piston to the prototype shooter mechanism. It is now able to shoot an object 12 feet.
Andrea of Business team worked on her vinyling skills. She learned how to properly set up the vinyl in Signblazer – a major accomplishment. Andrea also kept working on the Stronghold button design as well.
CNC Mill member Dustin tore off old supports for the triangular batter ramps as they were poor and couldn’t support much weight. Then, with help from Welding member Eden and Prototype member Devon, Dustin rebuilt new supports out of large blocks of wood that’re much better than before. Dustin then remade a list of materials needed to finish the batter and third Castle Tower and gave it to Mr. Black. He then ran the spindle warm-up program on the Mini Mill 2 and let other CNC Mill member Nanor run a part.
For dinner, Jacob and his family brought everyone delicious sushi rolls and dumplings. Sadly, there are no pictures to document this as the Photographer Samuel was out getting his haircut. He’d come back with less hair, but no sushi in his stomach. Yet he’d still write all about it in the blog as his other duty as Blogger.
Mika, our Pragmatic President, spent much of the day finishing preparations for Expo such as planning what goes where and when. She also cut stock for the Lathe and cleaned up the lab for Expo Day.
The lab closed at 12:30 AM. By then, the Lathe had cut some wheel-hubs and was ready to cut even more the following day for Clark Expo. Also, a safe-mode had been programmed for Snapdragon where the robot’s speed is lowered and the shooter is disabled. This will come in handy for Expo so people other than Team 696 Driving team members can drive the robot without posing a threat.
The lab was full of members by 3:10, listening to Mr. Hoard and Mr. Black give an update to our status. Among pointers on what needs to be finished, they also told the members what fields they could improve on.
Mr. Black and Mr. Hoard met with Business team members Anna and Arvin and with Blogger and Photographer Samuel in the Cinema room. While there, they discussed the Chairman’s Award – what needs to be done when and how.
Once back to the lab, Anna worked on the Google grant proposal. Other Business members Nicole and Andrea were busy in the business room. Nicole updated the brochure, flyers, and business cards. She also made a revised recruitment brochure. Nicole started the MailChimps email for Expo as well. Andrea spent the time selling light-bulbs and reorganizing the excel sheet showing sales. She also continued designing the button and planning for Expo.
Animation team member Christopher completed the hand tutorial and created a hand for the character. He believes that the head of the character will be completed by the next day. But by the end he had finished half of the character. His partner, Anthony C., completed the rest of the character during the afternoon and spent some time cleaning up the model. He made sure to bridge the model’s appearance to that of their reference and the human body.
Welding members Eden and Roupen finished the Sally Door and Rough Terrain with help from Mr. Larson. Besides this, the pair was also able to finish the Ramparts. Then, at around 7:30, Roupen began to prototype the shooting mechanism, leaving final assembly for the next day. He was also able to make custom slots into plywood thanks to CAM team which will hold a welded aluminum assembly. Mr. Larson and Dustin of CNC Mill crafted some aluminum parts to hold the assembly together.
CAD member Sipan finalized the dimensions for the base-plate. CAD team also chose the drive train and wheel configuration and designed and manufactured the prototype shooting mechanism. Sipan also acquired the center-to-center distance for the belt system.
James of CAM worked with Meetkumar of Prototype to finish up the drive base prototype. They constructed it in a way so that wheels could be mounted in many different configurations.
Karin and Lauren of Prototype worked with Lousaper of Lathe on adding some final touches to the Low Bar. They then worked on the Cheval de Frise Obstacle, collecting all the components needed to build it, including homemade pipe clamps.
Dustin of CNC Mill helped mount the High Goal to two posts and adding support for the posts. He also helped mount the Low Goal on the two same posts. Dustin worked with Sipan and Jonna to create a CAM program from a model made by the CAD team. They used the program to cut out two pieces of wood with slits, which they’ll use to test one of the robot’s mechanism.
As the meeting continued past 6:00, we were provided food. And so members gorged themselves on wonderful slices of pizza.
Mr. Widholm and Mr. Black developed a concept for a multi-stage telescoping box-tube assembly that will be used to deploy a hanging mechanizm. It will be able to extend about 2.5 times its own length, and is driven outward by contant force springs, and retracts with a motor-driven winch. They also performed loading testing of a 6 wheel drive configuration with 8″ pneumatic tires over Obstacles.
The lab closed at the bright and early time of 12:45 AM. In a few hours, members will fill it back up for the next Robotics meeting.
