CAD & Design

Electronics panel was configured and modeled in SolidWorks, new swerve modules were uploaded and updated. - Madi Wyatt

CAM Lead-Patrick I worked on testing Clem's Shooter Design, based on the testing that has been done so far, for placements in the current chassis design. Afterwards it became of interest to the several teams to know how much space we have left for the Hopper, and about how many balls we can hold. Here is what I've found:

-Please Note That All Values Are Approximated-

Size of Tote: 4,790in^3 Balls per Tote: 33 (40 were counted in total, however 40 do not fit)

Single Shooter- Space in Chassis w/out shooter: 9,038in^3

Space Occupied by single Shooter (as of 2:10pm on 1/27): 521in^3 (Shooter calculated as a triangle and the motor was not included)

Difference: 8,517in^3 (Shooter treated as at triangle; space immediately in front of shooter is included, although unusable)

Space available after Shooter and unusable space: 7,997in^3

33balls/(4790in^3)=0.00688935 balls/in^3

0.00688935balls/(1in^3)*7997in^3=55.09 balls

(This is under ideal circumstances; expect a number closer to 45 balls)


Double Shooter- Space occupied by 2 shooters: 1,042in^3 (Double the value of a single shooter w/out unusable space)

Total space taken by shooter and unusable space: 2,084 in^3 (Double the value above)

Space left for Hopper: 6,954in^3

0.00688935balls/(1in^3)*6954in^3=47.91balls

(This is under ideal circumstances; expect a number closer to 40 balls)

Things not accounted for: Climber, Feed, Alternative Shooter Designs, etc.

Mechanical

Programming

Tuning PID in shooter prototype

Strategy

Scouting (past week): We have determined everything we want to know in the app. The additional things that needed to be added are detailed in the picture below. All we have to figure out in scouting now is what Tableau graphs we want. We will be testing the app during the week one events. ScoutingBrainstorm.jpg

Scouting App (past week): We have the app mostly finished. All the sections of the game are in the app, with most of the questions as well. There are a few questions we still need to implement (fuel scoring, fouls, and field positions). We also are planning on implementing bluetooth as an alternative to QR code scanning. Where we are sending the data is yet to be determined (server or google sheets).

Field Elements

Communications

Attendees: Madi, Magdalena, Sully, Meghana

Agenda:

  • Send sponsorship letters

Notes:

  • GM, ISPE, SWE - letters sent off
  • Monitor FRC email for responses
  • Design business card
  • Look into team InDesign subscription
  • Full Team Meeting 1/21/17

Action Items (Moving Forward This Week):

This Week:

  • Metal is coming in
  • Building (or at least cutting metal) has started
  • Intake, gear, and shooter prototypes going well
  • Two shooters?
  • No turreted shooter
  • Shooter without flywheel tuned, though not perfect without flywheel
  • “Impressive flail” for hanging

Next Week:

  • Welding chassis
  • Hopper design (currently our biggest issue)
  • Metal shooter prototype starting today into tomorrow
  • List of motors, devices, etc. and how to power the robot
  • Finding a new spot for the electronics board
  • Water-jet pivot parts
  • Print a mount for the gear tooth (?) sensor
  • Test low-to-high gear programming for CVT pivot
  • Need shooting angles for the metal prototype - test with the wooden shooter
  • Test reliable speed, aim for reliable angle, then test many different distances (up to 13 ft away)
  • Build the ball release/loading station and hanging station

Notes:

  • Mechanical please relay ideas to CAD
  • Materials must be bought soon so we must be conscious of that
