Robo-Philosophy:Is it really "obstacle avoidance?"

This is a quick and easy one. The Roomba, as cool as it is, doesn't really "avoid" obstacles as much as just not keep trying to go through them. When your only sensor on a project is an impact/contact detector, is it still obstacle avoidance? If it isn't, what would you call it? I have a few bots that work like that-it doesn't make them any less robots.

floor cleaning

I am no robotics pro, but have an idea that has merit in my work. I want to build a bot, likely based on a heavy "battlebot" off the shelf chassis. This will be mounted with rotor swinging "swiffer" or similar treated dusters. The idea is to automate dust mopping of very large floor areas in a nuclear power plant, and possible adapt the machine to decontaminate radiologically dirty areas.

This robot is navigates by (avoiding) wall and cliff. It moves around the floor, vacuuming it.

As my first microcontroller robot, I have made a two-wheeled robot with bumper switches and edge-detction (because I have death-causing cliffs in my house). The … Read more
