Front supports removed to allow feeder to open wider. Promising results, needs more testing
Elevator vs. rivets problem fixed
Elevator works via code now. PID isn't in yet, that's next
Fixed DT motor that wasn't working
Elevator motor mount screws replaced, remounted
Corner brackets added to front side of elevator motor bar for more support, to fix flexing we saw when lifting
switched the position of the chain connection on the second stage to the side of the chain closer to the center
Discovered ramp design will lift our robot, not the other two. Bob & Chris are brainstorming w/team now.
Made wood supports and cut cloth for 1 set of bumpers (red). Need wood + noodles for second blue set
intake is taken apart to switch to 775pro and change reduction to 15:1. Also widened hole on lexan plate so we can change the gearbox without having to take everything apart.
can also switch to 30-18 pulleys
Challenges
it's good to feel challenged
Work for Next Meeting
Test feeder more. Is wider stance enough? More changes needed?
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)
