Control any device or robot microcontroller through the serial port using an XBee radio module series 1.
With this remote control no longer each time I have to think which is the system that I have to build my new robot control. Only I have to put a XBee in the new … Read more
There are two robotic eyes that move in horizontal and vertical.
This is a project to be mounted on a robot I'm building. These two robotic eyes, made very little money (just look at the list of materials used) and very easy to … Read more

It's not fully operational at this time.
This is a complete rebuild from v1.x, as you can see. This robot is much larger, and much more complex than v1.x was. I designed the decks using 3D CAD and had them … Read more
W.A.L.T.E.R. is my experimental and learning robot platform and will never be complete.  This is the first robot I built, back in 2006 - W.A.L.T.E.R.. It was named … 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!
