human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "efficiency improvement of measurement pose selection techniques in robot calibration"):
  Abstract: The paper deals with the design of experiments for manipulator geometric and elastostatic calibration based on the test-pose approach. The main attention is paid to the efficiency improvement of numerical techniques employed in the selection of optimal measurement poses for calibration experiments. The advantages of the developed technique are illustrated by simulation examples that deal with the geometric calibration of the industrial robot of serial architecture.

Includes members:
  Member "design of experiments for calibration of planar anthropomorphic manipulators":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "advanced robot calibration using partial pose measurements")
  Member "enhanced stiffness modeling of manipulators with passive joints":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "advancement of msa technique for stiffness modeling of serial and parallel robotic manipulators")
