I just finished up a little demo regarding the use of a simple artificial neural network (ANN) to control a mobile robot. The demonstration is only meant to introduce the concepts and terminology of neural nets rather than being something particularly useful. Also, this blog entry does not deal with *learning* in ANN's which is what they are most famous for. That will be the topic of a forthcoming blog entry and demo.
Here is the link to the report. If you get bored with the math at the beginning, you can scroll down toward the end where there is a Youtube video demonstrating the robot in action.
