Lots of testing and analyzing
Ha and Chris rebuilt the intake using the drive motors and gearboxes from the prototype. They then discovered (around midnight) that the intake doesn't work under some situations and the intake arms need to move out farther than the existing robot structure allows.
Lots more, see work for next meeting below.
Testing
5:1 gearboxes stalled when intaking cube right side up (13x13 dimension) even when there's no pressure to the cylinders --> switched them out for the 10:1 on the prototype
set working pressure at 30psi, moved carriage up to have more room for the arms to open wider (not restricted by the ramp support beams), removed inner wheels, untwist the ball joint on the cylinders to make the arms open wider
--> intake super well on the side (11x13)
still not great w/ 13x13 orientation
options
remove front support beam of ramp
--> allow more room for intake arms to open
cut longer back channel
reposition cylinders
--> tested ramp lifting frisbee with that setup, seems viable and stable enough, will probably add some extra support via corner gussets etc. to be safe
add another stage of reduction (3:1 to get 30:1)
switch to 775pros
change cylinder bore size to something like prototype (3/4" vs 1-1/16" on current design)
switch motor pulleys from 24-24 to 30-18 for like an extra 1.6 reduction
remove inner sets of wheels, make notch in arm lexan

Work for Next Meeting
- Mandatory
A large chunk of the front of the robot structure above the drivetrain needs to be removed (pictures to follow) to allow proper operation of the intake.
Front wheels need to be removed and the gussets holding the vertical tubing in place needs to be removed so the vertical tube can be removed.
Second stage of elevator needs to be removed to fix the rivet rubbing issue. If you know how to remove the second stage, be at the shop on Sunday.
The elevator motor is really loose and needs to be tightened, maybe holes tapped....
Remove drive gearboxes so they can be converted to single speed.
Elevator
Second stage of elevator needs to be removed to fix the rivet rubbing issue.
Remove elevator gearbox, tap 4th hole and remount it
Electrical
Finish with plumbing and wiring
Plan on individually actuating ramps, since raising an unoccupied ramp makes it jump 2 feet in the air.
Ramps
Smoke(?) and surgical tubing and spectra line magic that needs to be implemented to have the robot actually rotate the lift cylinders into position and then lift one or two other robots
Get frisbee bot, weigh it down to 130 lbs and drive it on ramp, actuate it, remove it and repeat like 50 times. Need to prove the cover material will hold up and not break.
Make bumpers
duct tape pool noodles to plywood
carefully fold & cut cloth, attach temporarily to bumpers, fold corners nicely and staple lightly if needed
mark where numbers go with chalk, or similar
remove fabric and iron-on the numbers
staple fabric to plywood (fold corners nicely pls)
attach L channel to plywood
drill some holes and make sure mounting/removing with pins is quick/easy
Testing
does intake rotate?
does intake intake?
does elevator lift smoothly?
does cube fall out
actual time for elevator to go full height & back
time takes for entire lifting routine (get on platform, deploy ramp, other robot climbs on, lift)
Pit Design
New pit wall for banner, sponsor stuff
Peg board for tools would be nice
Robot cart
fix handle
add second level again?
Make awards to give other teams?
Make buttons?
