Let's Make Robots!


Chess Engine Update 4/3/11

Well by luck I happened to find some one elses chess robot in one of the instructables contest. He was using Apple script to communicate with a terminal chess engine. That is about as much as I read into his project when I was like "Apple script?"

BomBot Nomadio GC205 R/C package

Our EOD technicians have received 6 BomBots from the Air Force. These units were designed to remotely detonate roadside bombs, (EOD). Four are new and 2 are used, but none have the transmitter, only the receiver. The transmitter is a bi-directional 5-channel, spread spectrum 2.4Ghz unit made by Nomadio, model GC205. I found the 15-page owner's manual for the R/C but it is woefully lacking in technical information.

Chess GUI Update (3/19/11)

Here is an update on my chess GUI (written in Processing) I have been writing. Video explains all.

OK, we dig bristle bots, and got a set of HexBugs as a gift. They're a blast. Now, since building the SHR, we view all things as potential robot bodies. At Target, … Read more

Maze Solving Robot V3. This one will work.

Not too long ago I received a care package from CTC. He sent me 2 of his arduino PCBs he designed. 


So that got me thinking, what would I build with it?

Well as this is going on, my highschool finally has its laser cutter installed. So it would be foolish of me not to use it. 

Here I go, making my highest verison of a robot yet. Maze Solving Robot V3.

Parts for Line following robot

I was thinking of ideas for my second robot and I thought that a line following robot would be good. So I want to build an arduino line following robot. I was wondering what parts I would need to follow the black line. Also I am still decieding wether I want to build a small chasise, similar to the 3pi robot, or buy a ready made one.

Bob Lifts Bear - The Sequel

Especially for Gareth, who requested a sequel. It's all a bit silly, really, but fun making it. My Robonova has a new head, which I've managed to squeeze a servo, led board, and camera into. The camera isn't very good quality, but is an introduction for me in Object Recognition software. Also included is a simple bot using a Picaxe with 3 servos, 2 for driving and one for "Ted". It has all been done using simple delays and timing in both Robonova and "Ted's Truck". The "gun" is a modified ball point pen and party popper. The "bullet" is filed down plastic.

This is a quadruped robot in prototyping using seeeduino mega, 12 HXT900 hobby micro servos, 3.7V lipo battery. Materials used are all plywood secured with small … Read more

Powering an Arduino: batteries/USB

I have an Arduino, with a Sharp IR sensor connected to it, and code that basically says:

If analog value from Sharp > certain value, turn LED on.

else, turn LED off.

When I plug my Arduino into my computer, and power it via USB, this works perfectly.

However, when I power it by batteries (4 x AAA), the LED is always on, even when there is nothing near the Sharp at all. Can anyone give an explanation of why this happens, or a solution to this problem?

Robot Competitions and other Events


Yesterday antonio.caciuc had the idea of compiling a database of robotics competitions. That's why I created this forum topic.

If you know any cool competitions or other events, please tell us about them here.

So I'm new to LMR, and this is my first robot. For now, it's just an Arduino Uno, a motor driver circuit, and two motors. The motor driver circuit I got from here: … Read more

Robo Scouts FLL 2010 Body Forward Challenge - test run

Here's a video of the Robo Scouts FLL team doing a test run from the 2010 Body Forward Challenge.

Thanks for watching!


I have seen this robot on the Arduino Forum and I find it so great and inspirational that I had to share it with you guys.

Servo'd Bluetooth'd Tamiya Bulldozer Robot


Hey cats. I spent the past 2 days writing a new design/control app for the ez-b and decided to make a new robot as a test platform. so yesterday i noticed i had a few of these bulldozer kits lying around, but i find them annoying due to the DC motor gearbox. A few years ago i started using modified servos instead of dc motors on the bulldozer kit. I get the odd email asking how i did that...

Soooooooooooo, i coupled the two together. A video showing how to build a servo driven tamiya bulldozer and the ez-builder

PhD in Robotics

Dear Friend in LMR,

I m planing to study the PhD this year. I decided to Make my study about Robotics. I need  suggestions for good Universities, Super visors and Project proposals. any advices, comments or suggestions will be highly appreciated. the degree that i m looking for is PhD in Electronic and/or Communication Engineering. the detailed profession  could be Robot Building Programing...etc 


best regards
