The day-to-day activities of Team 4099.

Workday 1/18/19

Programming fixed code to get the pneumatic pistons finished, and helped electrical test the pistons with the hatch panel intake.
Mechanical finished climber prototype and gripper (will test both tomorrow), and started testing hatch panel intake (wasn’t successful).
Electrical worked on finishing pneumatics and testing the manifolds. They also tested the hatch panel pistons and worked with motors.

Workday 1/16/19

Design almost finished the mecanum intake (cylinder mounting remaining). They almost finished pocketing the bellypan (need to add mounting holes for compressor and other electronics), and made progress on elevator bearings.
Mechanical continued to prototype the climber and hatch panel intake.
Programming still working on fixing code. A team member was working on trying to get info from the roborio for the Arduino to make the LEDs have different colors for different actions. A different team member got vision to align the drivetrain with the target, to some extent.
Business continued to work on the executive summaries and the video for the Chairman’s Award.

Workday 1/15/19

Mechanical continued prototyping.
Programming got stuck on things regarding vision. They figured out how to get over it by taking the time to comprehend what the documentation for limelight was saying… one of our mentors also helped them understand how to do the code for it. One of our team leads reviewed code and everyone who had to fix their code did so. A co-team lead was sick so he “called in” and was working on paths for the new game. They also worked on LEDs and using the Arduino to program them.
After submitting the Showbest Fixtures grant on Monday, Business has now started working on the executive summaries for Chairman’s. Work continues on for the Chairman’s essay and video.
Electrical worked on finalizing the testing board. They got all of the pneumatics working and now need to test it with the driver station. They also got a new RSL working.

Workday 1/14/19

Design updated the drivetrain and gripper. They’re working on finishing the elevator structure tonight.
Business discussed the next Girl Scouts event and the executive summaries, as well as other items that need to be completed for awards.

Climber meeting 1/12/19

People who attended today’s meeting brainstormed ideas for the climber. However, due to the snow, they weren’t able to stay as long as they hoped.

Workday 1/11/19

Mechanical continued to prototype subsystems.
Programming started working on the superstructure and fixed issues regarding Gradle.
Electrical worked on the board and fastened all the components. We also worked on the pneumatics system and RSL.
Business finished the Showbest Fixtures grant, now ready to be submitted.

Workday 1/10/19

Electrical worked on the testing board. We troubleshooted the pneumatics system and worked with the roborio.
Mechanical continued to prototype today. One challenge was figuring out compression and the variability of the size of cargo in the game.
Programming continued to write subsytem code and work with the limelight.
Design continued to work on the drivetrain assembly and the subsystems.
Business continued to work on the Showbest Fixtures grant. We are in the process of putting finishing touches.

Workday 1/9/19

Electrical worked with mechanical today and helped with building the hatch detaching mechanism. They also worked on pneumatics and trying to get the actuators to push the panel off.
Programming continued to code grabber and climber subsystems, as well as the dashboard user interface. They also set up the Limelight for vision.
Design worked on finishing the assembly for the drivetrain (adding gearboxes, sprockets, components on the bellypan) and researched designs for the 3 stage elevator and mecanum wheel intake.
Business continued to work on the Showbest Fixtures grant and analyzed options for tshirts. Based on certain sponsorships, we might be able to get a better plan.
Mechanical began prototyping different subsystems and started testing them against different metrics to optimize the efficiency of each subsystem.

Workday 1/8/19

Electrical assisted Programming with the test electronics board and the limelight. They also worked on pneumatics for prototyping the hatch cover outtake and started assembling a second electronics board for prototyping.
Programming coded the cargo intake and the hatch panel intake/dispenser, as well as teleop controls. They are nearly done with the controls for the elevator. They started work in the limelight camera but are having trouble opening the control panel for the camera on their computers. The new radio was also connected and determined to be functional.

Workday 1/7/19

Design worked on configuring the drivetrain for this year’s challenge, since we are increasing to 8 wheels, compared to 6 from last year. Other group members looked at previous year’s designs for the mecanum intake and three stage elevators and started designing the respective mechanism for our team.
Electrical worked on designing a practice electrical board that can be used for further testing. We worked to create a board that encompasses all the electrical parts. We also worked on a pneumatics system and getting the manifolds/solenoids to work properly.
Programming began to work on programming control systems for the elevator, creating preset positions so that the robot can more quickly aim its outtake. Research was also done into how to produce and execute autonomous paths. Business worked on assigning parts to the Chairman’s video, as well as starting to work on the grant for Showbest Fixtures. Those assigned to the video took a look at videos from past years to get a feel for what the expectations are for this year. Members assigned to the grant read and discussed the questionnaire, to brainstorm how to approach each question.
