A blue, tentacle-like gripping system attached to an Astrobee free-flying robot successfully latched onto a "capture cube" in a recent demonstration conducted on February 4, 2025. The experimental grippers autonomously identified and secured the target, showcasing potential applications for debris removal and satellite servicing in low Earth orbit.

Developed at NASA's Ames Research Center in Silicon Valley, the Astrobee system is designed to operate within the microgravity environment of the International Space Station (ISS). The system comprises three cube-shaped robots-Bumble, Honey, and Queen-along with associated software and a docking station for recharging. These autonomous robots navigate their surroundings using cameras and sensors while relying on electric fans for propulsion.

In addition to their ability to maneuver freely inside the ISS, Astrobee robots are equipped with perching arms. These arms enable them to grip station handrails to conserve energy or securely hold objects, expanding their functionality for future space applications.

The success of this gripping technology marks a step forward in the development of autonomous robotic capabilities for space missions. Enhancing robotic dexterity could play a crucial role in ensuring the safety and efficiency of satellite maintenance, debris mitigation, and other complex operations beyond Earth's atmosphere.
