Is anyone in to robotics?
I've made a few bots in the past, but I would like to see if I could make one on the cheap. Does anyone know of any good part shops? What are your guy’s projects?
Pic is my most recently finished robot.

I want to start playing around, so I'm looking for all the same answers.
Maybe you could tell us how you got started and what you've learned so far?

I learned most of what I know back in high school. Although they may not be super useful, I use to use these resources all the time.

I've been working on an entry-level robotics project for my school.

I'm sure I don't need to tell you that Arduinos or Raspberry Pis are great, cheap brains.

Frame, depending on what you want to do, can be cheaply made of scrap metal or wood. If you have access to 3d printing, it's possible to print shockingly durable parts using correct infill settings, and printer filament is cheap as fuck. Might check in with a local college, see if you can pay to use theirs.

Motors are gonna be one of those things you'll want to buy new.

Are there any good books on robotics or maybe mechatronics if that's not really available? Ive downloaded a ton of books on EE and programming but I'm lacking in the robotics and mechanics department.

I mentor for this team, FIRST is pretty great and Chief Delphi is a wonderful place to find information from a wide variety of active and upcoming engineers and roboticists...

I'm a newb, soon I'll be making a vacuum robot, with two switches (front and back) and a couple motors moving its wheels would rotate the opposite direction whenever one of the switches is pressed by bumping against a wall or something. If its trajectory is curved it should move around the house practically at random. I think I'll make the vacuum part with some computer fan, a box to contain the dirt and some foam to filter it and keep it in.

Our regional will take place in a few weeks.

Did your team compete yet?

I love the wheels on Stronghold robot.

Ours is april 7th, at lonestar in Houston. So we are waiting to compete.

lol thanks :P we had an interesting time of building an all water jet and welded chasis this year. We came in a pound over weight, so had to swiss cheese some things.

Oh, and we nick named it ten inch "wheels".

So what is up with your team's bot?

  No.1831

>>1822
That's exactly where I started with robotics years ago, it was built around the brush bar and motor from an old cordless vacuum, no electronics, just switches and a couple of relays found in a skip. It ate through batteries, but otherwise worked pretty well.

I personally gotta recommend some of the VEX EDR kits if some of you don't want to go FULL diy with some of this. I work with some of these for my job, and they cover a large range of possible builds, with bendable plates and such. Plus, their base pieces are a solid plus even when hooking up other things like Arduino brains.

I'm >>17437 over in that thread, and I believe some of the Robotics Academies courses are still going for free for the summer, though I believe they only cover EV3 and IQ robots. The ROBOTC software works with EDR and some older versions also work with Arduinos with some tweaking.

was relevant, thought i would post it.

I mentor for this team, love them to death, really want to teach the coders from "Hacking: The Art of Exploitation"
I feel they would benefit from the change of mindset, as currently the programmers are still being taught more to code monkey than to be creators.

I never got to do FRC (no money) but I did FTC for 4 years in highschool, and I mentor the team now. How many of you kids think you're going to make it to worlds?

I'd be down for a meetup. (St. Louis Region)

I have been getting into robots seriously lately, and am working on a couple of projects. However, my interest is on the intelligence side. One project is to have a UAV keep multiple surface vehicles in view, using only simple reactive behaviors. My other project is to create a communication system that would allow very heterogeneous robots to share their experiences (time & space) with each other for case-based reasoning and such. Both projects are still in early development, but glad to talk more about either if anyone is interested in this stuff.
