Astrobee is a free-flying robotic system designed by NASA to assist astronauts on the International Space Station (ISS). The robots are equipped with advanced technologies to conduct various tasks autonomously or through remote operation, reducing astronauts' workload and contributing to scientific research and station maintenance.
Description
Astrobee consists of three cube-shaped robots—Honey, Queen, and Bumble—designed for autonomous movement in the microgravity environment of the ISS. Each robot features sensors, cameras, a perching arm, and propulsion systems for navigation. They are powered by rechargeable batteries and utilise fans for movement.
Developed to replace the earlier SPHERES robots, Astrobee supports multiple functions, including inventory management, environmental monitoring, and station inspection. Its modular design allows for custom payloads, enabling researchers to conduct experiments remotely. The system's autonomy is underpinned by cutting-edge software, including mapping and localisation algorithms that use the ISS's internal environment for navigation.
Astrobee contributes significantly to space operations by automating routine tasks, which lets astronauts focus on high-priority scientific experiments and maintenance. The robots also serve as a testbed for advancing robotic technologies essential for future missions to the Moon, Mars, and beyond.
Special Applications
Astrobee as a Research Platform
Astrobee is a vital tool for testing artificial intelligence, robotics, and human-robot interaction in space. Researchers can upload custom software to explore new applications.
Educational Outreach
Astrobee is used to inspire students through competitions such as NASA's "Zero Robotics," encouraging innovation in robotics and programming.
