Chess Update

5.11.11 This update is running Grog's MRL program

The first video explains it well I hope.

 

5.14.11 The second video shows that I have changed the chess robot so it no longer goes back to a8 (the starting position) after every move. The code now calculates how to perform the next move from the location the chess robot's gantry crane ends at. I have also programmed in the ability for the robot to perform a castling move that the chess engine often does (this is not seen in the video)

Towards a auto-aiming servo controled directional wifi antenna

I'm planning a project to get an auto-aiming directional wifi antenna working to provide a long-distance repeater for a boat at anchor connecting to access points we don't control.I think this is a robot, but a simple one.  I think it's a robot because it senses its environment and responds to it.  Sadly it won't be very pretty but it might be useful.  It will definitely be fun ;)

A ridiculously powerful Arduino form factor board

Clicking around, I found this PIC32-based board.  It's the same form factor as an Arduino Mega board, but it's powered by a PIC32 running at 80MHz.  This is an 80MHz MIPS CPU too (a RISC CPU you'll see all over the place, and is somewhat similar to ARM) that has integrated USB and Ethernet support.  Not to mention 512k of flash and 128k of SRAM.  That's a lot of horsepower for a little board.  And it's only $50, that's not bad at all.

It is the Same DAGU arm in the prevous posts, but the controller is now different. The controller board is Roboduino … Read more

Robot Mesh Network

Hi there!

I haven't been on LMR in a long time... here's a video of my robot mesh network working. It's been a while in development. ;)

Planning to make a tutorial for it, and I will post it here, eventually. Woohoo!

Skip ahead to the 6:30 mark to avoid the boring debugging (yay for unedited videos!)

The embedded video isn't working for me, so here it is: http://youtu.be/KSGt83BzX74

Sorry for the updates - Google video

Google hosted it's own video service way back when I started posting on LMR.

I used to like Google's service better than Youtube, because it was free of ads, and had a better player - so I used that to many videos.

At the time I also thought there was a better future for Google than Youtube. Well, later Google bought Youtube, and now they are shutting down their own video service.

MyRobotLab Plays Chess with Patrick?

Hi,

This is a blog post for PM and anyone else interested.  I have been doing many updates to mrl, and have begun working on some tutorial videos.  Patrick Mccabe and I spoke a couple times regarding hooking up his great chess robot to mrl for a game engine.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
