Spooky is a system for Wireless Distributed State Estimation of multiple tracked subjects (mainly people and quadrotors), and control of multiple quadrotors, in a large-scale outdoor environment. It exposes an API using JSON over UDP for receiving state estimates of a multi-person multi-quadrotor system, and an API for quadrotor position control. Spooky supports the 3DRobotics Solo quadrotor, and provides custom hardware for person tracking. Named after the Quantum Entanglement phenomenon.
