Work Completed

  • Ramp surface was removed and recut to 37" long x 11" wide
  • intake rotation plates and inside slide bearings attached to carriage
  • feeder arms assembly made significant progress
    • assembled another 5:1 gearbox & attached
    • changed a few spacer dimensions ( 1/8" between bearing & pulley, 1/4" between wheel & bottom plate) because of lack of 1/16" spacers
  • prepped intake hinges (insert bushings, tapped, cut gears to fit)
  • made elevator chain attachment to second stage

Challenges

  • assembly guide would be extremely helpful next year (or for comp) because people were often unsure of how things are assembled (both the steps required and finding correct parts) even with CAD
  • trouble finding 1/16" spacers

Work for Next Meeting

  • make practice bot functional ASAP!
    • elevator
      • make sure carriage glides smoothly inside second stage
      • supports from crossbar near bottom need to be attached
      • cut & tap both ends a 1.5" & a 1.8" shaft for sprockets
      • attach top crossbar, chains, motors
      • test electrically when assembled
    • intake
      • If the one side works, Bob will get second back channel routed
      • one side arm still needs standoffs, belts and washers for the bolts attaching the motor
      • attach to back channel & hinge on elev
    • ramp
      • "The two sections are presently held with 3 rivets.  Rivets should be added along the side beams.  I should have taken a picture but there are 3 hole widths of perforated aluminum covering the 38" long pieces of extrusion.  Rivets should be placed in the middle set along the 38" long pieces.  No need to rivet onto the middle piece under the ramp surface.  Also, don't rivet anywhere in the 12 inches of tubing closest to where it mounts to the robot.  The presently riveted section is the end that will contact the floor.
        The total weight of the Perf Aluminum for a single ramp is 1.9 lbs. Total robot weight reduction is 5 lbs.  Total theoretical weight of comp bot with new ramp surface plus parts we need to add: 127.59." - Bob
