2/5/16 – Friday – Wired

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 lab closed at 1:30 AM.
