tightened bolts on intake arm gearboxes (+locktite)
tested elev. see video https://photos.app.goo.gl/N8iYKlmcnCaNxPJ93
draws 70A of current when trying to lift 11lbs intake --> drops
2nd stage weigh 17lbs(?) by itself, elev lifts that just fine
when constant force spring is mounted the elev would only have to lift 7lbs so this shouldn't be a problem
tested intake
tried taking out inner wheels & cut off parts of arm lexan where the cube was getting stuck
works pretty well at 30psi --> can run at comp w/o ramps (cube still gets stuck on diagonal but can still kinda hold/lift cube (doesn't fall out when jiggling, does fall out when spin at high speed))
drivetrain rocks back and forth when spinning bc of elevator, but probably won't be a problem on the field
red bumpers are done/close to done
Challenges
Work for Next Meeting
Intake to do: cut new lexan arms, new back channel
Test feeder more. Is wider stance enough? More changes needed?
modifications to try
adjust piston placement on feeder arm lexan
wider back channel --> move arm pivots further apart
actuate open/close arms
elev
replace motor (DONE)
Wait on this one -> Remove drive gearboxes so they can be converted to single speed.
Electrical
Plan on individually actuating ramps, since raising an unoccupied ramp makes it jump 2 feet in the air.
Ramps
Ramp work below probably on hold until design changes are finalized
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.
Continue bumpers
red set ready for numbers to iron on, staple and decide how to hang on robot.
Blue set:
make wood frames, measured from boards used on red ones. Also use same thicker brackets seen on red set
duct tape pool noodles to plywood. Get second person to compress the noodles so the material is snug after stapling. See picture Chris posted in #team slack today.
drape cloth over frames, cut
lay out where numbers go. 1 inch space between each letter, all of them carefully centered on each bumper. Every side needs numbers - for front split the "40" and "90" on each side.
remove fabric and iron-on the numbers
wrap cloth carefully around bumper, snugly, folding corners nicely.
Staple fabric to plywood
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 PID for elevator work as expected, dosn't slam it up or down, and doesn't over-accelerate? (<- for programming)
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)
