Bujaka! Or something :)

Kinect and wheeled versions under development

We were pointed out that tracked version might have problems on thick carpet or wet tiles. That is why we want to try the wheeled version and compare the performance on different surfaces. Any thoughts whether it will drive better then tracked version? Some pros/cons of wheels vs. tracks?

3D printed firearms(kind of)

first im sorry if this post is taboo and not allowed...feel free to remove it if so

 

first off i say "kind of" because a whole gun is not being printed. just the parts that are considered to be the actual gun.with all the reading lately and my interest in the subject i thought i would share what i have learned here in the blog.

Car alarm remote control repurposing

A while ago, I got hold of a car alarm unit and its two remote control fobs. When i hooked it up to 12V I realized that it didn’t  work, not responding to any of the commands from the two fobs even though their batteries were OK. Naturally, I opened up the unit to start harvesting parts and noticed the RF module within (the one that sticks out perpendicularly) and I figured it shouldn’t be too hard to use the module with an Arduino.

Pit-Droid (Clone) Rescue

Help me, help the droids!!              (see Full Version for more info)

I have 2 of these and want to get rid of them before I break down and start building them into a project that I have neither the time or space for.

TED the BiPed Core Code

 

After building my TED the BiPed (http://letsmakerobots.com/node/35632) and seeing K120189's BoB (http://letsmakerobots.com/node/35865) model take off with the 3D printer members along with a few questions in the ShoutBox about how to code a mini walker I figured I'd share my own version of a "delay-free" core code used on most of my bots. Maybe it will help someone get started at least and more likely someone will re-code it and share their better version. I use the same basic code for the rollers and the walkers but first the disclaimer:

Review: The Makerbeam Starter Kit

Hi all,

Last Monday I have been contacted by the people from makerbeam.eu asking if I would be interested in using their starter kit to build a 3D printer or similar machine. As I was actually planning to start working on a small CNC mill for PCB's I agreed instantly :) Makerbeam sent my kit on it's way on the same day, and knowing my intentions they also added bearings and extra long screws to mount them. Thanks makerbeam.eu people :)  

Arduino Uno

Hi there

I recently bought an arduino uno board  and i want to connect an external power supply (about 9v or more ) where i must connect it 

The new "Shark" model of our robot

Last year we spend considerable amount of time building the new version of our robotics vehicle. Here is the result - the small tracked vehicle which might be intereresting for researchers in robotcs, AI, computer vision as well as for DIY enthusiasts. All the model, assembling instructions and software are open source.

The Passing of a Loved LMR Member.

Unknown to many LMR members, but here from the beginning, has been Bondo the Dog. The best damn shop dog I have ever had the pleasure of knowing and never further than my ankles as I recorded almost every video posted here at LMR.

Bondo passed today at 5:00 PM. Bondo was my protector, companion, best God Damn shop dog who ever lived, and my best friend. He will be dearly missed. He was my hero.

Rocket Brand Studios/ CtC Update 1.14.12

Well, RBS had a pretty darn-good December and it seems the Tadpoles are exactly what folks have been looking for. I decided to take the move to the new house as an oppertunity to go through the whole shop, tune-up, square-up, shapen and/or lube just about everything I own. I did a good tear-down/rebuild of the CNC and I even built a whole sound-proof room just for milling.

Yup, RBS is growing faster by the day. 2013 is already shaping up to be a good one. 

Booyakasha.

 

 

Flea Market Find, Crawler Bot

Found this RC rock crawler missing battery cover and remote at our local flea market. For only $2 thought it would be a good start for a bot. Will use the arduino that I already have for this I think.

Disassembly was straight forward, 4 screws on truck shell 8 screws on board cover and all is exposed.

Mini Internet Controlled Robot Fighting or MICRF

A recent post brought me to this idea. most of use are old and young enough to remember when battling robots graced the tv with their awesomeness. But most of us weren't able to build them let alone ship the robot and operator out to the ring. so what if you only had to ship the robot?

So here was my idea.

Ebay mixed bag of robot bits

I mentioned on SPANR's page that I bought a bunch of robot bits on ebay some time ago and I started playing with them recently. This blog is my way of keeping track of what I got and some thoughts on what I can do with it.

First off, the biped.

I got trouble with the programming.

Hey guys, I'm new to this website and I have been building robots before and this website has been inspiring to me. :)

By comparing temperatur, Arduino tells you with RF Link if your room is too cold or too warm.

I would like to share my code. With this code your Arduino tells you by RF Link  if your room is too cold or too warm. You need 2 Arduino's.

It is just a part of a bigger project. But you can modify the code and make some great stuff. If their are some questions feel free to ask. RF link is amazing.

 

New

Hello everybody, I'm Acer. I'm one of Aaronsuper1's schoolmate. I'm a bit new to robotics. So I need help. I'm making a free form arduino. I'm waiting for aaron to bootload an atmega328 for me. Gonna buy parts tomorrow. Any tips?

BaseBot – Basic Robot Kit v1 Specs

Basebot is a simple Open Source Robot platform which intends to provide a good balance between price and performance. We want it to be as a base platform for boards like Raspi , Olinuxino , Carambola etc which can be mounted on top of it and they can control it serially. But it should be completely usable in standalone mode also.We did not provide any mounted sensors as we want users to use it as a flexible experimentation platform , while it takes care of simple robot like functions.

Magic blue smoke

As part of a mixed set of robot parts I bought on ebay I received this Dagu 4-Channel Motor Controller. On the back there was a trace broken so I soldered in a wire to replace it and hooked it up to the Rover5 (from the same set). Wired it to an Arduino UNO and programmed it to run a motor test. Applying power to the board, before the Arduino had even started PWM, one of the driver ICs began smoking.

Master Mk.1

This is the new blog for my MASTER robot. Given the suggestion about linking blog posts to robots, I thought I would start a build log and make a few notes about each part as I went along. I am already keeping the odd note about things so I dont forget them, but this way they are easily accessible and harder to lose (kind of like free cloud storage, but only for robot stuff)

 

Personal Update

I don't know how many LMRtians have been hit by the blizzard-I'm guessing a half dozen of us anyway.  We lost power for a while and still don't have interwebs at home.  I just made it back to work for the first time since my day at the hospital and this is the first chance I've had to check in.  Funny how LMR is my priority...

EXPECT US!

I'm not outing myself as a member of Anonymous or anything here (I would be flattering myself and lieing to say I had the skills to be a part of this), but more and more it becomes impossible to say I'm not on their side.

Robocop...ies

Sometimes, there are robots that are good as they are. It's not worth even to try to do my own spin of them. But because I like them so much I would like to have them/build them. So, I dedicate this blog post for reporting my assemblies of robot copies of other people famous robots in which I've just followed the instructions.

Arduino Wavefront Algorithm

First Up... If you want to find out what Wavefront Mapping is all about head over to the Society of Robots Tutorial. It has a great wtite up and its where I first learnt about it.

 

Basic's done, So lets talk about Map size limits.....

The Arduino 2560 & 1280 both have 8k of SRAM (where the map is stored)

I'm using an array of Int's, each Int is 2 Bytes, so max size would be the square root of 8k / 2.

8192 / 2 = 4096

Sqaure Root of 4096 = 64

NerdCam3D has arrived

Hi folks,

it really has been a while, my last post is months ago. But in the meantime I have made major progress. First of all I have bought an Axial Wraith, a RC-car that offers lots of hardpoints to mount and attach devices. Then some guy from the Geman FPV-community made a small GRP-case for the camera. In this way I was able to crawl through my backyard in FPV for the first time (see 1st attached video).

Happy St. Andrew's Day

I'm not what you'd call "religiously observant" but there aren't many holidays that apply specifically to robots or geeks (unless you count Bender's "Robonukkah," which some fans have placed in February and which I'll be sure to bring up around then, possibly with fembots wrestling in petroleum oil.)  So wired.com honored the long list of Scottish inventors in today's "This Day in Tech."

Of special note for hackers/open sourcers is this entry (directly quoted from article):

Why Do I LOVE New Projects?

 

Especially ones I've designed - especially when it seems like nobody else has done this before?

 

This should be as much fun as it will be frustrating . . . more soon . . . yeah c'mon!
