Tasks Completed

  • Design Completed for Wing/actuator
  • -Determine Motors
  • -Determine Start and match geometryTasks In Progress
  • Determine Material
  • -Lexan
  • -Sheet Metal
  • Beater bar requirements

    Fixed position inside the frame/ stationary position
    1 speed forward, 1 speed reverse (not full speed?)
    measurements (must stay inside the frame)
    As close to frame perimeter as possible, preferably coincident with it
    Material ideas: Wheel traction tread, drawer liner, surgical tubing wrapped about the bar
    Sturdy and easily replaceable (under five minutes to replace it)
    Inside the frame or deployable? MUST BE INSIDE SEE #1
    Sensor feedback;
    Ball sensor - know when one is entering the system -- possibly? Depends on how close we can get one for the conveyers
    NO status of spinning depends on # of balls currently in feeder, and whether there is a ball in front of robot. (accuracy?)
    DOESN'T MATTER AT THIS POINT Should beater bar spin constantly if there are less than 3 balls in robot, or only spin if < 3 balls and there is a ball in front of robot?
