Query: What Stands-in for a Missing Tool? A Prototypical Grounded
  Knowledge-based Approach to Tool Substitution   When a robot is operating in a dynamic environment, it cannot be assumed that
a tool required to solve a given task will always be available. In case of a
missing tool, an ideal response would be to find a substitute to complete the
task. In this paper, we present a proof of concept of a grounded
knowledge-based approach to tool substitution. In order to validate the
suitability of a substitute, we conducted experiments involving 22 substitution
scenarios. The substitutes computed by the proposed approach were validated on
the basis of the experts' choices for each scenario. Our evaluation showed, in
20 out of 22 scenarios (91%), the approach identified the same substitutes as
experts.
