Emotions and Motivations as behaviour architecture

Hi all, a few days ago, I started designing the behaviour-based architecture for my robot Hurby. I thought to design it as a Subsumption architecture (see my previous blogs) in which different behaviours compete to be selected as dominant, and hence move Hurby accordingly.

Robot Class

I am in the process of submitting a course proposal for an adult evening education program that would introduce people to robotics. One of the entries that I must fill in deals with expected material costs. I would appreciate feedback on what would be appropiate expenses and whether the school should include the costs as part of the registration or if the student should buy the components as needed. I am in favor of having an option not to build.

On a similar note, would it be better to first offer a course in "C" programming geared to a possible robotics controller board?

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.

Pet (work in progress)

I have not built my first robot yet - waiting for the parts. But I have the plans for my second robot ready. He, just a little ambition :D.  My second project will be a prototype for a robot that can be sold as a consumer robot. I will call it Pet - working title.

This is how I imagine it. When you order Pet, it will come in a nicely designed box. In that box you will find a shiny sphere, a little smaller than a soccer ball. One size of the ball will be flat. You will also find a smaller box that contains a base plate with an electrical cable. No on/off switch. No manual.

Flash Memory of Arduino Uno


Sketch uses 13,308 bytes (41%) of program storage space. Maximum is 32,256 bytes.

Global variables use 2,082 bytes (101%) of dynamic memory, leaving -34 bytes for local variables. Maximum is 2,048 bytes.
