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 "control barrier functions theory and applications"):
  Abstract: This paper provides an introduction and overview of recent work on control barrier functions and their use to verify and enforce safety properties in the context of (optimization based) safety-critical controllers. We survey the main technical results and discuss applications to several domains including robotic systems.

Includes members:
  Member "constraint driven coordinated control of multi robot systems":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "adaptive task allocation for heterogeneous multi robot teams with evolving and unknown robot capabilities")
  Member "safe certificate based maneuvers for teams of quadrotors using differential flatness":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "control of mobile robots using barrier functions under temporal logic specifications")
  Member "the robotarium a remotely accessible swarm robotics research testbed":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "what can robotics research learn from computer vision research")
  Member "torque saturation in bipedal robotic walking through control lyapunov function based quadratic programs":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "episodic learning with control lyapunov functions for uncertain robotic systems")
