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
- bumpers
- comprehensive weight loss plan --> google spreadsheet
- miscellaneous
- New pit wall for banner, sponsor stuff
- Robot cart
- fix handle
- add second level again?
- a peg board for tools would be nice
