Work Completed

  • Quite a bit of elevator progress
    • Carriage done, minus side brackets, which may need to be routed(?)
    • Outer stage sides mounted to robot
    • Middle stage assembled with bearings/rollers, minus bottom piece (waiting on carriage)
  • Ramp aluminum bent/trimmed a bit more, but most efforts put towards elevator.
    • perf alum attached on ramp using rivets & spacers --> need more spacers or just use rivets
  • Battery holder & support bar for it trimmed small, lightened and mounted

Challenges

  • Ran out of (or couldn't find more) 10/32 bolts, had to scour Champaign.  Got enough to finish rollers.

Work for Next Meeting

  • make practice bot functional ASAP!
    • elevator
      • part 0114 from CAD needs 3" cut off one end, then mounted.
      • supports from crossbar near bottom need to be attached
      • change the order of spacers/bearings on the inside sliders (was this done?)
      • 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.
      • If the one side works, Bob will get second back channel routed
    • ramp
      • dampener on bottom of frame
      • figure out how to actuate ramp pistons (more pistons? passive? CAM style drop?)
      • attach pistons to frame, somehow
      • finish attaching perforated alum
      • intake
        • intake hinge plates
        • cut arm lexan plates
        • mount motors (10:1 arriving soon hopefully? otherwise the 5:1s might be ok)
        • implement actuation
      • electrical
        • test robot
        • controls iteration
        • test auto
      • drivetrain
        • if wheels are wobbly / shafts are too long, add a spacer on the outside and put the bolt over
