Interests - Aduino, BeagleBoard, Computer Vision, AI

I'm a long-time electonics and robotics enthusiast, now retired and living in London.

I'm currently working on an Arduino-based Tracked Robot, as preparation for B4 - a BeagleBoard-based 'bot with which I will be exploring computer vision and AI algorithms.

I blog about TrackBot, B4 and related topics at the RAREblog.

Large Motors and Gearboxes for Robotics

Since I was a kid, I have always looked at things as "robot pieces".  When "normal" people walk into a toy store, they see toys.  When I walk into a toy store, I see "robot pieces".  So, today at the Chibots meeting when Stuart was showing the Minds-I 6x6, I did not see a 6 wheeled vehicle, I saw "robot pieces".

iRobot Create Linux Drive Application



The following is a simple Linux application I put together to control a iRobot Create from the Linux command line.  Super simple, and easy to modify to your needs.

 

The code supports piping commands from a control app to this one.  I write my Linux robot applications as a series of commands that I pipe together.

 

Example:  sudo ./glview | iRobotCreateDrive

 

glview is a app I wrote that interfaces to the Kinect and guides the Create based on…
