I built this robot for a friend of mine in exchange for some awesome machine shop work.  It features the following components: Max 96 Round Mobile Robot Platform … Read more
This is my first robot. It has a Arduino for control and a Adafruit motor controller.  I still have a lot of coding to figure out, having never programmed before … Read more
Hi guys, Unfortunately I can not build the robot to the end because my RC is broken. I took a few pictures and two movies. … Read more
Turn your servo into a powerful linear actuator
Provided you have the tools and the servo you can built this for under a couple of bucks. The actuator extends with a rate of about 50mm/min. It is rather slow but … Read more
Now with cool video of a real life military prototype! This is an easy to make 6 wheel drive robot platform designed for rough terrain. The chassis is made from 3 … Read more

This is the arduino rover complete kit plus IR turret from www.robotshop.ca. I am useing the Motor shield from Adafruit to control the pan and tilt and 2 motors. … Read more
OSR is a major work in progress, It is controlled by the arduino Mega, OSR will has bluetooth capability, so i can control it from my verizon droid eris(android … Read more
Hallo Guys!!! Because my Remot Control of "Fishing robo(A)t" is broken, have I a little time for next robots. I wanted always to build a Line Follower robot. This … Read more

quad encoder read speed

This is as much a programming problem as it is a mechanical issue I guess.
A few of us are working with quad encoders at the moment and I'm just wondering about ideas how to overcome a problem I've encountered using some.
I'm using interrupt on change to count encoder ticks and also reading a 16 bit timer for the interval between ticks on each motor.

Hello, my first post and first attempt at a robot. I visited the Manchester (UK) Mini Maker Faire recently and saw some biped robots and I decided that I just had … Read more
This is a little board I made in anticipation of Mr. Bdk6's toolchain for the LPC1114. BdkdevThis toolchain is amazing.  Really, if you are wanting to break away … Read more

Use an Arduino to get to the Moon

So, this whole Maker movement has got you excited, and the rocket you are building in your backyard is nearing completion.  But you haven't decided on a navigation computer yet.  You were thinking of using a laptop, but your daughter needs it for school.  Maybe a Beaglebone Black.  Darn!  Seems they are sold out everywhere.  You look around your lab, but all you can find is an Arduino. At first you pass right over it.  But when you can't find anything else, you start to wonder, "Could it get me to the moon?"

ComMotion Shield for omni and mecanum wheel robots

After building my first omni wheel robot I realized how difficult it can be to monitor 4 encoders and drive 4 motors so I designed the ComMotion shield. As the name suggest the shield is designed for motion control but as I ended up with 2 spare serial ports I decided to add communications abilities to the shield hence the name ComMotion.

What every robot builder needs to know about

It is probably safe to say that every member of LMR is interested in machines that interact with their environment.  Interacting with the environment means getting information from it to provide feedback to the machine.  In the  electronics and computer worlds, "information" means "signals."  And since most of our robots use digital signals, whether with discrete logic chips or some sort of computer, and our machines need to do some sort of processing on those signals, we all need to be familiar with Digital Signal Processing (DSP). One note before we go on.

Makes a loud, piercing noise!
If anyone would like a look, I've posted a 3D printed loud noisemaker on Instructables and Thingiverse -  The Orange Screamer -  which is proving to be rather … Read more
