| Abstract: |

| A finite point configuration is said to be caging a planar body, if
the set of Euclidean motions of the body not hitting
the points of the configuration is bounded. Caging configurations are
important in robotics and are a popular topic in computational
geometry.
We argue that caging is best understood in topological terms,
manifesting itself as nontrivial linking of certain closed curves
(in the group of motions of the Euclidean plane), which can be
translated into effectively computable invariants of pairs of
framed planar curves. |
