Engineering Notebook – 10/26/17

Attendance:

Charles, Alex, Drew, Zach, Danielle

 

Goals:  

Builders

  • Attach linear lift

Programmers

  • Review codes for linear lift
  • Discuss possible controls for the linear lift

Meeting Notes

Programmers:

  • Thought about the elements of code before applying
  • Added Boolean (true or false code that dictates what happens if true, code is used. False the code is not used) to dictate up and down motion on the linear lift
  • Started “A” button (on controller) one level down (6″)
  • Started “Y” button (on controller) one level up (6″)
  • Worked on claw prototype (16″ to 11 ¼”)

Builders:

  • Worked on linear lift prototype (16″ to 11 ¼” height)
  • Decided to move out wheels ½” each from the sides

 

Engineering Notebook – 10/19/17

Attendance:

Alex, Zach, Drew, Danielle, Charles

 

Goals:  

All

  • Downsize the example “claw” mechanism to better fit the cryptobox blocks
  • Work on driving test bot
  • Mount wiring and distribution modules onto the competition robot

Meeting Notes

  • Split into 3 groups
    • Claw group
    • Test bot group
    • Wiring/Distribution group
  • Claw group [Zach, Drew]
    • Started to downsize the claw mechanism
    • Worked on creating a new “hand” for the claw to gain better grip on the blocks
  • Test bot group [Alex, Charles]
    • Attached vertical supports to the test bot
    • Attached wheels
    • Attached motors
    • Put the wheels on a direct gear contact setup instead of chains like the competition robot
  • Wiring/Distribution group [Danielle]
    • Mounted wiring on the competition robot
    • Attached wiring from the wheels to the distribution module

Engineering Notebook – 10/12/17

Attendance:

Alex, Zach, Drew, Danielle, Olivia

 

Goals:  

All

  • Get the drivetrain completely built with electronics
  • The programmers:
    • Review code & ensure they understand each line
    • Understand the relationship programs variable & phone names
  • Copy the program to a new name % ADD whatever lines necessary to:
    • Add another DC motor (to operate the lift)
    • Add servo motor (to operate the claw)

Meeting Notes

Builders

  • Created chains to drive the wheels by cutting and fitting chains
  • Attached metal brackets or L brackets to C channels so it could be attached to frame as support

Programmers

  • Reviewed what all the codes did
  • Then they moved to help the builders with the robots electronics
