The rational of the contribution is to describe, in an ontology, what the goal of an assembly activity is in terms of what assemblages need to be created from what parts, how the parts connect to each other, and how the robot can interact with them.

To competently use, select and combine such instructions, robots need to be able to find out if different instructions describe the same task, which parts of them are similar and which ones differ. text/html 2014-06-05T11:38:52+00:00 Anonymous (anonymous@undisclosed.example.com) https://knowrob.org/blog/application_of_knowrob_tidying_up_a_kitchen?rev=1401968332&do=diff Application of KnowRob: Tidying up a kitchen In a recent demonstration, the bachelor project SUTURO of the Institute for Artificial Intelligence at the University of Bremen presented its results.

Examples are tasks such as unscrewing a bolt, pouring liquids and flipping a pancake. This aspect is often abstracted away in AI planning and action languages that assume that an action is successful as long as all preconditions are fulfilled.
