12 DOF hexapod kit now sold by SparkFun

The 12 DOF hexapod kit from DAGU is one of the simplest hexapod kits ever! You can buy it from SparkFun here: https://www.sparkfun.com/products/11497

Quick and easy to assemble, the body only consist of 12 leg segments, 12 foam rubber feet, 12 servos and a base plate with a hole pattern that allows controllers and sensors to be easily mounted.

Spider controller

The DAGU Red back Spider controller is an Arduino Mega (1280) compatible controller that is especially designed for driving a large number of servos. All 70 I/O pins are terminated in servo compatible 3pin male headers as well as the standard female header and the power supply is a switchmode power supply delivering 5V @ 3A from an input voltage of 7V - 32V.

Yet another ambitious beginner robot project

I'm planning of building a small Arduino-based robot, but it seems there is a lot for me to learn. I'd be grateful of comments from more experienced and knowledgeable people. I consider myself an absolute beginner on electronics front, though I do know some of the basic electrical components and connections. I'll start with some questions.

A ball bearing motor is a strange thing - we made one, and.. gave it a little too many amps :D
(Update II: New video, we managed to make it run on a standard racing pack 7.2V (no clue to how many amps - but not enough to kill a large elephant, only enough to … Read more

Easy Robotics opinion question.

While encouraging David C. To learn to program for something other than a robot, I realized I was being kind of a hypocrite. I enjoy building the hardware more than programming. Not that I don't enjoy programming, just that the initial thrill of seeing the the completed machine is kind of an experiential apex. Is that the norm? Is it kind of like that arty/techy thing we had a while ago?

Charming Robot Shirts, cases, & other products

Dave has been making robots in a different medium than is typical here.  I probably can't keep up with the tech discussion, but if you're at all interested in a fun and light hearted robot t-shirt or case for your iphone, check out my Zazzle store.  These are the robots of your childhood!

What I think would be fun...

    I think we have a lot of talented people here who would all look at a problem different.  I think it would be fun for someone to think of a problem that you could solve a million different ways and have everyone take a shot at trying to solve it if they want.  Then I think it would be interesting to see all the solutions.  If the problem was simple than you could have people try to solve it simpley and straightfoward and others who would think outside the box and over complicate it.  It would be like a challenge but the prize would be th

Oh my am I ever excited

Good news everybody!

I'm new. My name's Cam. I've never built a robot or any electronic circuit but for some reason I'm super-confident that I'll be awesome at it.

 

I have a little bit of scripting/coding experience, I'm hoping at least some of that translates over to robot building. I'll have a heap of help at least to start off with from a friend of mine, he's never built robots either, or really done much in electronics, but he's an engineer ooh wow

Nothing works. Where did I go wrong?

I have tried to build my robot according to the schematics below, but it is not working. Where did I go wrong??

Have fun with it.

My First LMR Blog... first blog ever?

So Im new here...

I have already started my first robot. And as soon as I have got it together to a some what more presentable state I will submit it as a project :)

When deciding what to create as my first robot, I looked at the beginners stuff and thought I could do that, but I still want to be diffrent which is why I am building a 3 legged walker. I'll Hopefully upload a video or two with some photos in the next few hours.

Thanks for reading and enjoy your day.

This is my very first line following robot that is built around ATMEGA8. Construction and circuit are quite simple. Such a name- GOOFY is given because robot movements are somewhat clumsy. But hey! Its still working and doing his job very well! :)
