Smartphone Guided SPHERES May Assist Astronauts on ISS

NASA’s Human Exploration Telerobotics project aims to create robotic systems that complement the crew during space missions. Small flying satellites known as SPHERES for Synchronoized Position Hold, Engage, Reorient Experimental Satellites, may do just that.

SPHERES could be used aboard ISS in the near future to conduct interior inspections and record photgraphs and videos. “The tests that we are conducting with Smart SPHERES will help NASA make better use of robots as assistants to and versatile support for human explorers — in Earth orbit or on long missions to other worlds and new destinations,” said Terry Fong, project manager of the Human Exploration Telerobotics project and Director of the Intelligent Robotics Group at NASA’s Ames Research Center. SPHERES are also being used as a test bed to explore formation flying and docking maneuvers that may translate to full fledged spacecraft.

SPHERES are bowling ball-sized flying robots controlled remotely by an astronaut with a smartphone. The smartphone, Samsung Nexus S, utilizes Google’s Android operating system, which is open sourced and easy for NASA to modify. The smartphone provides computing, power, cameras, and sensors to the satellites.

The SPHERES, originally designed by students at the Massachusetts Institute of Technology, have been tested aboard ISS and recently gathered and delivered motion data to their astronaut handler utilizing the smartphone controller.

The video below from Google explains how the smartphone integrates with the SPHERES to perform robotic operations.
