I have found a new and interesting job: designing a mobile robot’s mind! I have started working on designing necessary decision making system to control a small mobile robot. It ought to act as a vacuum cleaner or something similar. It is not apparent for me what I should do exactly; however, I designed a simple two layer subsumption architecture that wanders around while avoid obstacles. If I am true about my position in the group, I intented to design three other modules in addition to what I have implemented: map building, self-localization, and dirt-cleaning planner to cover the whole map efficiently. I have some ideas on all of them that I will discuss them gradually.
