Thanks for making your designs and code available... it's a very useful resource. I'm also interested in behavioral-based robotics, using Lego Mindstorms (among others) to try experiments. So far I have built a simple robot, more like a Humvee really, that roams around and avoids objects. What's neat is that it can carry a small laptop (I have a Fujitsu Lifebook P1610) and a webcam, with the eventual goal of adding robot vision using OpenCV. Your articles have inspired me to blog about it. BenB Thom, great site! Thanks for making your designs and code available… it’s a very useful resource.

]]> Comment on My Framework Code by Xander http://roachnet.wordpress.com/robotc-code-library/#comment-21 Xander Fri, 10 Jul 2009 05:10:58 +0000 http://roachnet.wordpress.com/?page_id=131#comment-21 Thanks for this page. This will make it so much easier for me to get my hands on the latest version, see what's different from the previous ones, etc. I've started using subversion (SVN) for all my drivers now, it's a nice way to keep track of all the changes. TortoiseSVN integrates nicely with the file explorer, so it's very easy to use. Thanks for this page.

In his book he explain his programming method using NXC (Not eXacly C) and FSM (finite state machine) which if i understand properly is a type of behaviorial programming.

Put all the changes in a single file in the root of the zip file. I think keeping the whole thing together is the best way to go for now.

]]> Comment on AreaRover – Adding Wall Following with the Lego Ultrasonic Sensor by Xander http://roachnet.wordpress.com/2009/06/25/arearover-implementing-wall-following-with-the-lego-ultrasonic-sensor/#comment-5 Xander Fri, 26 Jun 2009 06:28:28 +0000 http://roachnet.wordpress.com/?p=86#comment-5 I'm currently using your framework to create a ball-seeking and retrieving robot. Your framework makes it easy to add new ones and even exchange behaviours with other people since they're kept in separate files. This makes collaboration much easier. I would love to see an example of a ballistic behaviour since I am going to need one of those very soon and would like to see how you'd go about setting it up.

]]> Comment on Brooks’ Subsumption to the behavior-based framework by Xander http://roachnet.wordpress.com/2009/06/22/brooks-subsumption-to-the-behavior-based-framework/#comment-4 Xander Tue, 23 Jun 2009 21:35:53 +0000 http://roachnet.wordpress.com/?p=56#comment-4 Inhibition is a need to have for the model robot I want to build. I need a way to turn off the object avoidance when a red can has been detected by the camera, because the same sensor is also used for determining how far the bot still needs to go before it can close its claw on the can. However, once the can has been grabbed and lifted, I want object avoidance to resume as normal but switch off the can detection behaviours.

]]> Comment on What is Behavior-based Programming? by troach242 http://roachnet.wordpress.com/2009/06/19/8/#comment-3 troach242 Sun, 21 Jun 2009 00:04:51 +0000 http://roachnet.wordpress.com/?p=8#comment-3 I am going to write a follow-up article on Subsumption this week. My code was written to implement a subset of Brooks Subsumption theory called fixed-priority arbitration. This is a more simple implementation that uses one arbitrator and implements brooks subsumption, but not inhibition. What people have found, is that in many cases, the full subsumption architecture is overly complicated and rarely exploited to its full potential. All but the most complex robots can be built with fixed-priority arbitration where higher order behaviors subsume lower behaviors. I will go into more detail in this week's post.
