Meeting Notes

  • Two motors can drive the same port. (Only if the battery has a charge)
  • Mikayla is learning how to make an IR seeker program such as the program will continue to run told to stop. Also “If’ and “Else if’ statements work best for an IR seeker program.
  • Danie and Tyler worked on the scissor lift, fixed the rising issues
  • One of the motors was offset
  • Decided on December 7,2014 for our first competitions
  • Color choices for the sweeper is green, pink, yellow, and possibly blue
  • Jacob learned good program design such as:
    • Indents
    • Naming function with a verb to describe them
Button Motor Number Motor Speed
7 1 & 2 75 (Raise)
8 1 & 2 -75 (Lower)
5 1 & 2 50 Raise
6 1 & 2 -50 (Lower)

Meeting Notes

Experiment

  • Today we moved are rack and pinion closer to the center of the robot.
  • We also added a second scissor lift.
  • We tried adding a dumping mechanism to get the balls in to the goals.

Result

  • The motor was not enough to raise the two scissor lift, the gear spun clicking and the scissor lift would not lift and the motor started smoking.
  • We then ordered a twelve inch axle which we are going to put in-between the two rack and pinions.

Meeting Notes

  • Scissior lifts
    • 1/2″ square tubing- sturdy but heave, takes a lot torque
    • L-shaped metal- sturdy and lighter than the square one ,but
      hard to attach things to
    • Tetrix flat pieces- lightest of all, but rather wobbly
  • We decided to go with the scissor lift made of the tetrix pieces
  • Was to dumpballs onto different sized goals
    • Bucket spinning on axel
    • Drawbridge going to goal
    • Natural tilting bucket
