To do

To Be Done

  • Finish design for Ball constraint in kicker
  • Find where we need mechanical stops
  • Raise battery
  • Locate kicker stop
  • Clearance for electrical
  • Area (Bottom Pan for electrical between motors
  • Side Restraints

Conflicts

  • Kicker path and D.T. stabilizers

Design Analysis

Stress Analysis

  • An alumninum rod fixed where the bearings are

Current Design

  • shooting takes 1-2 seconds
  • a kicker strikes the ball through 2 bars (cradle)
  • Linked with intake with a motor in the cradle structure pulling and pushing intake

Equipment Requirements/Size

- Weight

 - 45 LBS

- CIM motors

 - 4 mini CIM
- 2 regular CIM

- Control

 - PWM or CAN, but PWM may be preferred as it may be faster
- cRio CAN is derived from RS-232 with max data speed of 115,200 bps.

Sat Jan 11

  • Still working on Fundamentals for design
 * Calculating how far the kicker has to move
  • Calculating if motor driven is possible for Kicker
  • met with collection
  • integrate our cradle with the collection
  • What type of material should we use
  • Better to have a longer kicker than a lighter one

Accomplishments/Results

  • Kicker must move about 80 - 90 degrees
  • If you go any less than that you need more motors
  • How to stop kicker motion
 * nylon strap
  • blocking plate

End of Day Design

Sun Jan 12

  • Continue work on 3D design in inventor
  • Determine geometry of Our kicker to the ball and cradle
  • Our kicker has to be curved at some point so that we get the max speed into the ball rather than rotation
  • We Finished drive trains CAD
  • Worked on CAD for shooter

Tues Jan 14

  • worked more with intake to get a linkage working
  • messed some more with the geometry of the shooter
  • Made a physical mock-up of the shooter
 *cradle
  • kicker
  • Worked more on the CAD mock-up

Current Design
