+ | ===== Reasoning about logged data using knowrob_mongo | ||
+ | The knowrob_mongo package contains methods for accessing information in the MongoDB database via KnowRob predicates, for example the logged tf pose data or perception results. | ||

"What is the probability of a certain task was failed during the execution of a plan?" is shown as an example. It is also one of the use-cases what we want to show in our ACS'13 paper. | "What is the probability of a certain task was failed during the execution of a plan?" is shown as an example.
