متن کاملWhat Can Robots Do? Towards Theoretical Analysis
Robots have become more and more sophisticated. Every robot has its limits. If we face a task that existing robots cannot solve, then, before we start improving these robots, it is important to check whether it is, in principle, possible to design a robot for this task or not. For that, it is necessary to describe what exactly the robots can, in principle, do. A similar problem — to describe wh...
