It seems like a simple task. A robot crawling along a floor comes upon an obstacle. It stops, turns, and moves in a different direction.
Or is it so simple? Perhaps a robot with a more complex thought process would, instead of turning around, climb over the obstacle. Or push it out of the way. And what if the environment changes and it too becomes more complex? What if the obstacle was trash that needed to be picked up? Or a pet? Or a baby? What then would the robot do?
The kind of interactions we as humans take for granted are a constant challenge for today's roboticists. It's questions like these they need to ask and try to answer when designing and building an autonomous robot capable of sensing and interacting with its environment.
