Work Completed

  • part 0114 got trimmed down to 18.5"
  • intake back channel trimmed to 18" & deburred
  • elevator second stage and carriage are put together minus the inside rollers and intake plates. Will add those tomorrow when the spacers arrive and the intake rotation plates are routed.
    • carriage doesn't slide in the second stage super nicely but it could be the missing spacers
  • elevator first stage side support are tapped and drilled, will be mounted
    • first stage verticals are tilted forward unevenly. could be fixed after mounting the side supports and the crossbar at the top, but dunno..
    • apparently the belly pan/frame was assembled a little off? no one seems to know details
  • finished mounting perforated aluminum on one ramp using rivets. Will order washers for comp bot ramp. out of material, need to route/order more.
  • set up a makeshift testing hinge for ramp with round tube on bottom rung of ladder. Probably need something a little stronger.

Challenges

  • people don't read notes, so they missed the part where it says to "make extra sure the inside distance is correct on both top and bottom of stage"​
  • waiting for parts to arrive

Work for Next Meeting

  • make practice bot functional ASAP!
    • elevator
      • supports from crossbar near bottom need to be attached
      • assemble inside rollers when spacers arrive or make some
        • change the order of spacers/bearings on the inside sliders
      • When attaching top to middle stage, make extra sure the inside diameter is correct on both top and bottom of stage, and carriage moves smoothly, no brackets rubbing, etc.
      • when fully assembled, test it electrically
    • intake
      • One back channel piece has been routed, should be on router table.  Cut this to 18" length, Bob should have marked the side to cut.
      • Use above piece to mount one side of feeder and test it. This prob can't happen until Tues night, since we're waiting in mcmaster parts for intake.
