One of my dreams was an idea to make a robot whose wheels were like a ferris wheel, so they'd pick up balls as they turned. It was a JS idea

@user That could be useful for driving ranges

my dreams frequently end up having a suspiciously high amount of video-game related things incorporated into it which is a reflection of the fact that i have no life and play video games way too much

I think I remember dreaming about Dennis coming back and doing a "TIO update crunch" and just adding all the new languages/updates all at once

@Dudecoinheringaahing Well, the ball containers would hit the ground at some point, making it harder to turn. It might work slightly better on a soft golf course than on the thin carpets used for robotics competitions, but it's still a lot worse than having a ball picker-upper at the front or something that spins balls inwards, uses a conveyor belt, or vacuums them up
@hyper-neutrino That sounds almost like the title of an r/shittymoviedetails post for some reason

@user Well, if you had the wheels deposit the balls into a separate storage place at the "top" of their revolution so that they're empty at the group

Then the robot would have to go backwards or smth

@user "In HN's dreams, you can see a lot of video game references. This is a suble nod to the fact that HN has no life and plays video games too much" :P
Q: Take a square integer matrix A. Will the maximum absolute element of A^2 always be greater than or equal to the maximum absolute element of A?

@user Here's an image to confuse you further

What if you had some sort of gear thing to make one wheel between the front ones spin backward and be slightly smaller

@Dudecoinheringaahing the square of [1 -1 ; 1 -1] is the zero matrix
a different question is, for any sq int matrix A such that there exists some sq int matrix B for which B^2=A, will there always exist one such sq int matrix whose maximum absolute element is <= A's max abs element
since the zero matrix also has [0 0 ; 0 0] as a square root

And the other way
@RedwolfPrograms Hmm, how would that work?

@user What if you made it so the scoop was sort of "spring loaded" so it'd move into the wheel, deposit the ball into some mechanism inside, and pop back out?
That'd be a ton of work though
Dude coinheringaahing

@hyper-neutrino Hmm, that's interesting. I'm trying to verify my brute force answer to this, which generates all nxn matrices with elements chosen from -absmax(A) to absmax(A) (where absmax is the largest absolute element), and it still works for [0 0; 0 0] because it is its own square root

@RedwolfPrograms Yeah lol
We only have 6 weeks to make our robot, it's too hard
hyper-neutrino
hyper-neutrino
it isn't too hard to make the scoop deposit the ball at the top of the wheel

Just put a machine gun on it and play to win

Wait, the scoop could actually be on the side of the wheel and not protrude beyond the wheel
@RedwolfPrograms I'm afraid we're only allowed to shoot balls and bunnies, not bullets

Yeah, I'm confused about why you're making this so complicated? There kind of wheel scoopers already exist :P
user

I guess my dream just made a worse version of them then :P
hyper-neutrino
hyper-neutrino
just have the scoop run between a track made of two rods at the top, so the scoop passes through and the ball gets pushed onto the track
Redwolf Programs

Have a giant spike and impale the balls

just attach a vacuum to your robot ez

Make the balls magnetic and have a giant electromagnet hovering above the range :P

@RedwolfPrograms Like this? :P

Yes, exactly
Maybe an EMP could work too
Or a giant spring loaded hammer

That would kill the robot too
Crab-style

borrowing dude's idea, just get a really strong electromagnet and just make your robot have minimal metallic parts and use it to yeet the other robots

or just attach a bunch of blenders to the side of your bot and do the mega speed

@hyper-neutrino Why would you want to do a bunch of rendering?

Have it drive up alongside the others and steal their balls, so they're basically working for you
Have it disassmeble the competition and build one really big robot that grabs all the balls and delivers them to you

Crab, but as a mad robot

Have a really long telescoping arm on it, then make it move to the center of the arena and spin really fast
Dude coinheringaahing
Dude coinheringaahing
We're overcomplicated it, just send a person out onto the range with body armour and a bucket to collect the balls :P
