JEM Internal Ball Camera

The Int-Ball, also known as the JEM Internal Ball Camera, is an experimental, autonomous, self-propelled, and maneuverable ball camera that is deployed in the Japanese Kibō module of the International Space Station. It was delivered aboard SpaceX CRS-11 on June 4, 2017. The Int-Ball is intended to perform some of the photo-video documentation workloads aboard the ISS. The Int-Ball was designed by the Japan Aerospace Exploration Agency (JAXA) and is controlled and monitored by a team of ground controllers.

The Int-Ball naturally floats in the station’s zero-gravity environment, allowing it to maneuver freely within the ISS. It weighs 1 kg (2.2 lb), is 15 cm (5.9 in) in diameter, and is propelled by an array of 12 small electric fans mounted on the ball’s outer surface. The Int-Ball’s motion control system is capable of executing a rotation on any axis, and is also capable of overall movement in any general direction.
