learning robot

Hey guys. friend and i are working on a project. we are trying to build a robot that will basically be able to follow a path. if there are obstacles in front it will go around them and then continue to the finishing point. no we also want it to learn about its surrounding. so if we bring the robot back to its starting point it will be able to get to the finish with out bumping into objects.we are planing to adopt this robot here https://www.instructables.com/id/Make-a-wall-avoiding-Robot!/?ALLSTEPSwhat do u guys think is it possible and if so how.the robot will learn by creating a grid in its memory using multi-dimensional arrays.

Learning Electronics -- Resources?

Hello! I'm a 13 years old geek. I am good at programming and the software stuff, but doesn't know anything about electronics. When I see Arduino projects or other robotics/gadget projects here at Indstructables, I feel very sad because I don't know the nitty-gritty. So what are the resources on web available  where I can learn about electronics, robotics and the likes?  I know there are many books, but they're more of theory which takes a college-student to understand, and I'm not that. I want the books, websites which makes us understand these a little simpler way with practical stuffs too. Please list any website or tutorial you know. I am also eager to make those hexapods and robots.  Regards Jack

In one of my classes, it was necessary to review Laplace transformations. I realized that, after many months of not using it, I had become extremely rusty in integration by parts. Once I saw the basic idea, it slowly came back to me. Therefore, and I know the core audience isn't exactly appropriate, I would like to do a series of math related instructables AND I would like to have one or two collaborators. There's a few reasons I'm doing this.... 1. I feel the internets lack a resource with basic instructions of advanced mathematics (there's a few good resources, but it's mighty hard to find a "how do I do this" sort of thing). 2. Teaching is a great way to refresh the memory 3. The potential of comment feedback could be a good indication on what else should be covered. 4. Perhaps earlier basic introduction is useful to someone? Or not.... 5. The focus, in addition to how, is why such things are done. You won't find that on wikipedia :p Some topics to include (not necessarily individual projects) - and the projects would be something like How to solve _____. Basic definitions - notation Differentiation Integration Fundamental theorem of calculus Chain Rule Separation of Variables Integration by Parts ODE's Laplace transform Fourier Transform Anyone interested in collaborating - even on one subject? Then, anyone interested in looking at these? Not necessarily to learn how, but to see why it's done? For the why/application - I mean given a real world scenario... I promise, the application portions won't be boring (at least not for the nerdy type) ;)

Anyone want to learn electronics?

A while ago I was going to start an electronic tutorial video podcast, but that took too much effort to make everything professional looking and well thought out.  I want to retackle this project by having a video whenever i feel like it (at least 1 a week) answering questions that people ask or just want a video on because people generally learn better via video than reading some boring text :P  Also, this podcast isn't going to be editted or anything, because all of that stuff just takes away all of the fun and just becomes boring. So, in short, I'm going to start an improvised video podcast answering people's questions to the best of my abilities. Anyone have any questions that they would like to have answered?

How to build a simple computer from a cardboard box (or 2) and some marbles?

Quite a few years ago (around 36-40) I read about a simple computer, made of a cardboard box, some dividers, and using 2 groups of colored marbles; whereas the object was to tilt the box  and one marble would fall through.  Depending on which of the 2 colors came through (pretty random) a move was made in the game (a simplified version of tic-tac-to).   Wrong moves were removed and eventually the "computer" learned to win the game every time. BUT I can find no reference to this, nor the book it was in.   I don't remember the title nor author, but it was very much like the book:  "1, 2, 3...Indiniry" by Gamow (it is not this book, I have it and have read it through several times looking for it).  I have been looking for this info for about 20+ years, and decided one of the more sciencey readers amongst you all might remember  it, the book or something to give me a clue to where to find this.

Where/How to learn about Engineering basics?

I have been recently looking into engineering and how to build different equipment, and am wondering where people learn to do these kinds of things.  The first thing I saw that had inspired me was a man who built a glove and software that replicated finger/hand movements in motion capture fashion that was useful to me because I do 3D animations which is helped by motion capture.  I had built it because he had left a step-by-step tutorial on how to do so, and it worked perfectly.  The thing that upset me was that I have no understanding of how these parts work, I just bought the equipment and put it together based on his instructions.  So I am wanting to ask how I learn about this stuff?  Things that I am wanting to learn I believe are geared around Micro controllers (EX: Arduino), MotionTracking Device's (EX: MPU-9150), Multiplexers, and other stuff that revolves around that.  I have been looking for tutorials and books to help but have had no luck.  Also one of the most frustrating things I faced when putting the gloves together was that I had no idea what 'SIG', 'VCC', 'GND', or any of those meant.  I understand that I might sound pretty stupid, but I am genuinely interested in this am looking to learn about it, I just do not know how to.  Thank you for any reply in advance.

Why have 'they' not made a cellphone with a learning remote?

How often are you spending more time looking for the TV, DVD, Stereo remote than the time it would actually take to just get up and push the button on the unit? Cordless phones have 'pager' function where you can press a button on the base unit causing the handset to beep. A lost cellphone may be found by ringing it. But very few manufacturers of entertainment system (that i have come across) include a "finding' feature with the units' remote control. WHY NOT? Surely Cellphone manufacturers could "easily?" include a learning remote with the rest of the 'hugely useful' features on them the we use EVERYDAY...like FM radio, biorhythms, international roaming, bottle opener. You see my theory is-- a. that I tend to know exactly where my cellphone is 99% of the time. It is personal. b. The TV, Stereo etc. remote on the other hand are communal. I mean other poeple, like my kids, use them often and thus the remote gets left ANYWHERE. So the two ideas i have put forward is 1. Learning infrared remote in a cellphone and 2. a pager for a remote (new thread pending)

Resourses to learn about what's going on in the tech projects?

Hi, I'm new here to instructables. I will like to firstly start off and say that I think of myself as pretty tech savvy. I do seem to know the most about technology in general (especially computers) at my school. To be honest though I do attend a small school. I know I'm FAR from understanding everything about technology, but technology in general intrigs me, and I'm always curious to learn more about it. I recently discovered this site and saw all these cool inventions people were making (especially in the technology category in my opinion). I understood the basic concepts of them such as using leds and stitching them in clothing's and stuff like that, but after realizing people are using things called "arduino's" and other chips and such to do all this, I had no idea whats going on. I am little informed on electrical and computer engineering. So call me stupid if you'd like, but does anybody know of any resources that could help me learn and understand things and such of what's happening?

Help with a learn to solder project using infrared LEDs

Hi, Recently my company remodeled our EE lab and was going to throw out a huge amount of electronic components, since they didn't care I took all of them instead.  Next spring I am likely going to teach a small class on basic soldering. I can solder well enough to teach others, but I can't design circuits at all. I'm looking for some kind of project that could use some of the parts. The coolest parts are infrared LEDs and Phototransisters. I have thousands of these Fairchild QSC113 and QEC122 http://www.fairchildsemi.com/ds/QS/QSC112.pdf http://www.fairchildsemi.com/ds/QE/QEC123.pdf I also have around 30 small piezio sounders/buzzers no part number A couple hundred red and green short leg LED (Can't do a cube matrix as the legs are short for a angled board level mount) Lots of small switches I know I have 3904 transistors as well as many other flavors but I don't have the numbers in front of me I also should have any small caps, resistors, diodes, and zener diodes I know I also had several 555 timers and lots of resonators and crystals in various speeds Circuit goals Through hole only No Surface mount Able to be made in 1-2 hours by new solderers Class will be limited likely to less then 10 attendees depending on # of soldering irons I can find Circuit has to do something with an effect like sound or light so they feel like they created something I would like any extra costs to be under $40 for the whole class as I will likely have to pay for it Each circuit needs to be able to be taken home Ages will be from about 14 to 75+ I do not have have most of my extra parts sorted but I do know a general "type" of the parts so feel free to use a part and I'll see if i have something similar. If I like your circuit I'd be glad to send you 250 of each of the infrared LED/phototransiters The class will be taught at Hoosier Recreation Workshop -Steve

Tools to get when learning/playing around with electronics???

Hi.   I've recently started making small electronic projects, first starting with a pack I bought from an electronics store that pretty much comes with all I need (resistors, transistors, springs, wires, batteries etc) it's fairly amateurish and for a beginner. But I have some more involved things i would like to start.. and a few little things lying around I would like to play with, take apart and salvage for working parts etc.. So I am at the stage now of wanting/needing tools for jobs. I was wondering if anyone could provide me with a list of things I would need? The electronics repair kits I have found on the internet usually cover computer repair/electronic repair tools for around $80 including screwdrivers, pliers, alligator clips, torch, and soldering iron kit etc... and I have considered buying an all in one kit liked his but if I was too just buy a few things at a time what would be the things I should get first? I'm hoping to over time build up a large collection of quality tools for future long term list so I don't really want anything cheap. And safety is definitely a factor.  If anyone had any idea's or could help that would be great, Thanks. Vulnic

I have a basic knowledge of electronics, but need help with this one. Is it very complicated? I'm not sure of specifics at this point, such as how many and what types of batteries (AA, AAA, 9V) what voltage, etc., just need to know how to build a circuit for this purpose. My project will use a single bright L.E.D, or possibly more, (maybe 3 watts each) and I would like to have the ability to plug it up if someone either doesn't have the batteries, or would just prefer to plug it up at all times. How does the device switch between battery and plug in? Thanks for anyone's time and help! I really do appreciate it.
