Hart, P. E., Nilsson, N. J., & Robinson, A. E. (1972). A causality representation for enriched robot task domains. Stanford Research Inst Menlo Park CA.
Existing robot projects in the field of artificial intelligence have concentrated on tasks wherein the robot must excite an action in order to change the current state of its environment. In this report we consider other families of task, such as those involving the inhibition of an action or the maintenance of the current state of its environment. In particular, we propose a representation for knowledge that a robot would need if it is to solve problems from such task domains.
