How do you shoot a moving target algorithmically?
LHACK4142 replied to LHACK4142's topic in Science & Spaceflight
I guess I was unclear in the OP- I don't want to intercept the target with the robot's chassis, I want to shoot the target with a previously unmentioned shooter. Thanks for the help already given, though- they are interesting reads. -
I'm programming a robot with a shooter on it and I want to hit a moving target (well, hit a stationary target while the robot's moving, but it's just a matter of reference frames). It's got a holonomic drivetrain (so it can detach its heading from its direction and thus aim anywhere while moving) and the shooter's angle is adjustable. The velocity of the shooter is also adjustable, but I'd rather not use that feature (too inconsistent on this robot) Anyone got any advice on doing this?

I got Covid, imported from Arizona! For the third time! And my robotics team's next competition is Thursday, so I'll have like no time to program an autonomous script! Hooray!! It could be much worse, though. On this team, I have the support of many other capable programming peers and mentors who can certainly write a autos, unlike the team I captained where I was the sole programmer and the lead pretty much everything.

Here's a nice little guide to flag making that I found interesting: https://s3.amazonaws.com/ClubExpressClubFiles/622278/documents/GFBF_English_1964413892.pdf?AWSAccessKeyId=AKIA6MYUE6DNNNCCDT4J&Expires=1711751756&response-content-disposition=inline%3B filename%3DGFBF_English.pdf&Signature=oUQYZkTaq5n0r1y8d%2Fy3Zq%2B%2Fbec%3D

totm march 2020 So what song is stuck in your head today?
LHACK4142 replied to SmileyTRex's topic in The Lounge
This song has been stuck in my head since me and my hotel roommates played it at 2 in the morning before a robotics competition while working on the robot... in a hotel room: Hopefully my team's media lead lets me make a season recap- if she does, I'll use this as the music. Such a beautiful piece! -
I've been investigating photography a little but am confused on how lenses, and focal lengths, really work. This question has been with me since I was a little kid playing with magnifying glasses, actually. So, many pictures show light entering a lens as straight lines: But if only light rays parallel to the lens could enter, you would only be able to see an area equal to that of the lens, right? Since you can see the entire sun, and not just a lens-sized portion of it (pictured), through a magnifying glass, this type of diagram must be incorrect. Other images (below) show straight lines through the lens, which kinda confuses me; don't lenses specifically bend light? And what are the lenses in these pictures supposed to be doing? So, what exactly is a lens doing, and where are the light rays coming from, how are they being manipulated, and how are they ended up?

"SR-71, half off!" Also, this thing looks reasonably cool... ... It's called the NASA Mini-sniffer.

Dont think so. The less imagination you have the more kits you buy ¯\_(ツ)_/¯

totm aug 2023 What funny/interesting thing happened in your life today?
LHACK4142 replied to Ultimate Steve's topic in The Lounge
I made panettone and am making ciabatta bread for Christmas. Panettone is a labor of love if there ever was one- I even thought I broke our stand mixer and pored through the dough looking for a tiny piece of plastic. To have it for breakfast, you have to start it the day before and wake up at like 5 AM. It was intense. Now I'm making the ciabatta. It is SO MUCH EASIER. Ahhhhhh....... -
