Pre-STL Day 7: Maintenance & Anticipation

Intake

Wooden blocks were added tonight to the practice robot to keep the polycarbonate base of the intake from touching the ground. This is one of a series of adjustments to the intake to make it more efficient, fluid, and functional. The polycarbonate base often gets caught in the carbonate causing jams and reduced mobility.

Shooter/Indexer

Overkill with all of the tanks.

Even though the Frisbee hard stop was working last night, it was not today with the pin having trouble sliding the stopping plate up and down. This was solved by changing the hard stop to delrin and maintaining the mounting plates to aluminum. Also, students and mentors created two cross bars for the indexer. They also worked on shooter wheel mounting plates. Lastly, the team added temporary air tanks to the practice robot to allow for more shooting cycles and less refilling.

Drivers

Abhi and Jonathan Lee continued driver practice in preparation for the upcoming competition.

Sensors & Programming

Students and mentors tested hall effect sensors using Slipstream as a power source, because of drivers using Overkill to practice. The hall effect sensors would detect the presence of a magnetic field. When magnets are placed on the indexer mechanism, a feedback mechanism is created to determine whether or not the indexer mechanism is completely engaged in the correct position. On the programming side, programmers fine tuned various code for indexing and shooting.
