DECISION MAKING MECHANISM, METHOD, MODULE, AND ROBOT CONFIGURED TO DECIDE ON AT LEAST ONE PROSPECTIVE ACTION OF THE ROBOT
First Claim
1. A decision making mechanism, said decision making mechanism being operable to decide on at least one prospective action of a robot from a set of actions of said robot by:
- computing a prior probabilistic representation of a prior environment state;
updating of said prior probabilistic representation with targets of a new observation on reducing at least one uncertainty in a posterior probabilistic representation of a posterior environment state to be reached after an appliance of said at least one prospective action, wherein said posterior probabilistic representation is a probabilistic representation resulting from said updating;
determining an information gain between said prior probabilistic representation and said posterior probabilistic representation by use of at least one information theoretic measure; and
evaluating said at least one prospective action by adding costs of executing said at least one prospective action to said information gain.

Abstract
A decision mechanism is configured to decide on at least one prospective action of a robot from set of actions by: computing a prior probabilistic representation of a prior environment state; updating the prior probabilistic representation with targets of a new observation on reducing at least one uncertainty in a posterior probabilistic representation of a posterior environment state to be reached after an appliance of the at least one prospective action, the posterior probabilistic representation resulting from the updating; determining an information gain between the prior probabilistic representation and the posterior probabilistic representation by use of at least one information theoretic measure; evaluating the at least one prospective action by adding costs of executing the at least one prospective action to the information gain. Furthermore, an improved action planning for robots is provided and can be implemented in various robots investigating scenes for their actions.
