NASA's Valkyrie, a humanoid robot, is undergoing testing at the Johnson Space Centre in Houston, Texas.

The Valkyrie, named after a Norse mythological character, is designed to function in areas compromised by human activities, such as natural disasters.

NASA is collaborating with robotics firm Apptronik to explore the potential advantages of humanoid robots for earthly applications.

Apptronik is developing Apollo, a humanoid robot designed for warehouse operations and manufacturing.

 Apollo is designed to operate for 22 hours per day, with a replaceable battery allowing for four hours of work.

Apptronik CEO Jeff Cardenas believes the potential of Apollo's capabilities is boundless as advancements in software and development continue.

It is possible that in the future, the phrase "unstructured spaces" will also include references to physical space.

The robots are designed with modularity for easy adjustment and suitability for various applications.
