Work Completed

  • completed feeder mounted to elevator with gearboxes & everything
  • new & improved ramp frames are partially assembled, need the spacers and perf alum top
  • electrical done/almost done??
  • robot turned on
  • weighed ~100 + 13lbs per (new) ramp including pistons, tube, hinges, rods, etc. so like 126 total

Challenges

  • pneumatics problems so unable to drive for now
  • still 6lbs overweight at the moment

Work for Next Meeting

  • make practice bot functional ASAP!
    • elevator
      • test electrically
    • intake
      • If the one side works, Bob will get second back channel routed
      • still needs lexan back stop
      • test for:
        • does it intake with full pressure to the clamping pistons? for both cube orientations?
          • need to put spacers on clamping pistons?
        • can we get away with 4 wheels vs 8?
          • does it have enough grip? does it drop when we move elev up @top speed? spin around? rapidly change direction when driving while feeder is in the air?
    • ramp
      • Route and drill 6th Ramp side tube
      • Cut a tube for top of ramp
      • Find another 32.5" 1x1 tube or remove one from the practice bot ramp frame (the one without a ramp surface)
      • "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
