1/18/16 – Monday – Pizza Wheels

As it is Martin Luther King Jr. day,  Clark Magnet has no school this beautiful Monday. And so the Robotics members took full advantage of the absence of school and walked into the lab at 9:00 AM. Greeted by doughnuts and a long day of work ahead, they went to their designated spots with doughnut in hand. Except they ate before going as Team 696 does not like ants invading our lab.

To begin the blog update, we begin our journey in the Cinema room where Jacob and his mentor are hard at work as members of Simulation and Analysis sub-team. Commonly known as MATLAB team, they’ve been recently trying to figure out why their simulation’s drag does not compute to reality. After taking some videos of the ball being launched from the robot’s prototype mechanism, Jacob was able to figure out the velocities by the difference in distance betwixt frames. Finding how little drag affected the ball in reality whilst the simulation had a lot of drag, the pair decided to do more research into drag itself. After digging around a little, they discovered something called “Reynolds number.” Simulation team thinks what they’re experiencing is called “drag crisis,” which is where the drag decreases during the launch of an object because Reynolds number increases. Further research is needed though before any possible findings can be conclusive.

Roupen, the other Welding member, tried different wheel positions and compression on the prototype shooting mechanism. After several different combinations of the two, one was finally found that maximized performance and so a huge adjustable shooter mount with piston-actuation mechanisms was constructed.

Mikia of CAD 3D printed out a wheel hub, and Anthony K. completed the bumper supports. Claire made more progress on the electronics plate.

Dustin of CNC Mill assisted Devon of Prototype in creating more ramps for the Castle Tower Batter as well as fixing up the old ones that had been oriented wrong – needing to have their supports redone. However, the two didn’t have enough plywood to complete two more ramps that will be needed later. Dustin and Devon then helped out other CNC Mill member Nanor and Jonna of CAM on creating another side for the Castle Tower. After this, Dustin also helped Karin and Lauren of Prototype with constructing the bases for the Obstacles.

The trio needed the wood to create two more bases for platforms and ramps.These two would make four new ones in total that the group has made. After assembling the platforms, they helped Nanor and Dustin of CNC Mill and Jonna of CAM with building the second High Goal. A little later, Lousaper worked the Lathe at the request of Mr. Black.

Nicole of Business team finished the new Team 696 brochure. She also updated the sponsor brochure and our business cards. Andrea brainstormed more ideas for the Stronghold Team 696 buttons and edited sponsors. Andrea organized the Business room and also did tasks for Mr. Black such as creating copies of important documents. Anna did vinyl work, Chairman’s essay, and worked on the Business Plan. Final member Arvin also worked on the Business Plan and Chairman’s essay alongside Anna.

Mr. Black procured additional lumber for the Obstacles, for which 696 members were very grateful of. He then tested five different tires to determine which one would suit the robot best for its future tasks. Mr. Black also designed the custom CNC machined wheel hub, unpacked the kit of parts, and even placed orders for wiring supplies. The whole team thanks you Mr. Black for the hard work and passion you put into Team 696, we couldn’t do it without you.

Mika, our brilliant President added items to the “need to buy” list for Mr. Black. She then went to help Business team in their activities as well as provide feedback on their recent output. And of course, she looked over all the teams to make sure everything was being done in a proper efficient way.

Alexander, our clever Vice-President decided to order parts in place of transmission assembly. He also finalized the superstructure prototype, but it still needs iteration and perfection. Alexander worked on the bumper design, finishing the basic concept but it still needs to be translated into a CAD model. He also inspected the designed wheel hub for accuracy, checking to see if the hub could actually be used as it was designed to.

For the final half-hour prior to the “official” ending of the meeting at 6:00, all members partook in cleaning up the entire lab. This included organizing, taking out the trash, and even vacuuming.

The lab closed at 9:10.

1/16/16 – Saturday – All Along the Watchtower

Meeting at Clark at 9:00 in the morning sharp, all sub-teams save Business met in the Cinema room to discuss robot design ideas throughout the entire team. The reason for this is to get everyone on the same page on what we will be striving for during this Build Season. Also, this enables members to voice their opinions on what could make a better robot.

During this time and throughout the day, Business team members Nicole, Andrea and Anna and Arvin worked hard in their room. Nicole worked on the Brand Guide content, with emphasis on the logo sections. Andrea spent the day continuing work on the button design whilst Anna and Arvin worked on the Google grant and business plan.

Bhavin of Programming configured the Axis Network Camera so it could transmit a video stream from Centurion to GRIP for vision processing. Jake continued honing his skills in Java programming using some CodingBat exercises. He also worked with Jack, Robotics’ former President, on wiring the Axis camera and light-ring to the Power Distribution Panel on Centurion.

Roupen of Welding and Eden split up for the day. Eden went to help the mechanical team on Obstacle building while Roupen thought of a way to shoot the ball. He decided on a flywheel design and spent the rest of the day until 7:40 building it. He also got James of the CAM team to help him pocket pieces of plywood to house bearings.

Mika, our powerful President, worked on getting a “to-purchase” list made. Alexander and Mr. Black focused on the mechanical needs while Mika worked on the electronic and wiring items needed to purchase. She also helped Claire set up the electronics plate.

The conclusions reached by the end of the day are as follows: Wheels <2″ diameter do not effectively shoot the ball with 1 CIM powering direct drive. Unlikely to work much better with more motors. Insufficient rotational energy in the small wheels. 4″ dia and greater wheels shot the ball with acceptable range/force when direct driven by one CIM (insert Video). Having ball in contact with wheels, then energizing wheels, does not sufficiently accelerate the ball. Close shooting into high goal works very well by human hand, and seems like it could be mechanized. Impacting the ball seems highly variable so far, at least in tests by human hand. Side mounted wheels (rather than top and bottom) could be an option to use bigger wheels. Spring loaded plunger seems promising, if it can be made precisely using linear slide components. A prototype wooden box with rollers driven by two cordless drills also seemed capable, but did not not launch the ball nearly as far as the spring loaded plunger.

The lab closed at 8:30.

1/15/16 – Friday – Drive Base

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.

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.

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.

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.
