NASA’s Valkyrie Blazes Trail for Robots in Space
NASA is pioneering the use of humanoid robots for future space exploration missions with its R5 Valkyrie robot. Standing at 6.2 feet tall, Valkyrie is designed to withstand the harsh conditions of space and perform tasks too dangerous for astronauts, such as spacewalks and construction projects .
Valkyrie is equipped with dexterous hands capable of using a variety of tools, and it can be operated remotely by astronauts aboard a spacecraft. It also features cameras and sensors to map its environment.
“Valkyrie is a major step forward for robots that will explore Mars and aid astronauts on the journey there,” said NASA Associate Administrator Thomas Zurbuchen.
Tests so far have focused on Valkyrie’s mobility and ability to manipulate objects in simulated space environments. Future plans call for launching Valkyrie to the International Space Station by 2025 to further develop and refine its capabilities.
AI and Machine Learning Usher in More Capable Robots
Advances in artificial intelligence and machine learning are enabling rapid progress in developing increasingly sophisticated and capable humanoid robots . These intelligent robots can learn new skills and even teach each other through the use of cloud robotics.
For example, researchers at the University of California, Berkeley programmed a robot named BRETT (Berkeley Robot for the Elimination of Tedious Tasks) to perform basic household chores like sweeping and mopping. After just a few days of practice, BRETT became highly proficient at its assigned tasks.
“Robots like BRETT foreshadow a future where machines will be far more integrated into our everyday lives, helping with routine duties around the home and office,” said lead researcher Pieter Abbeel.
|Dynamic balancing, locomotion over uneven terrain
|Disaster response and search & rescue
|Carry payloads up to 14 kg, operate for 90 minutes
|Inspection of hazardous industrial sites
|Bipedal locomotion, pick & place objects up to 2.3 kg
|Warehouse automation, last-mile delivery
These more physically capable robots can safely interact with people and unpredictable environments thanks to responsive, real-time motion planning guided by integrated sensors. Their improved autonomy will enable deployment across a wider range of real-world scenarios.
The Next Giant Leap: Robots in Space Exploration
NASA and other space agencies have ambitious plans to send advanced robots deeper into space in coming years . Robots like Valkyrie offer major advantages for space exploration compared to humans – they don’t require food, water or oxygen, aren’t susceptible to cosmic radiation, and have the strength to lift heavy objects under low gravity conditions.
Valkyrie and other prototype robots are being tested in Mars analog environments on Earth. The data collected will inform development of future generations of space robots tailored to support crewed missions to the Moon and Mars.
“Robots will allow astronauts to focus on high-level tasks like science experiments and exploration while robots take care of routine chores,” explains Dr. Taskin Padir, director of robotics at NASA.
The Next Industrial Revolution?
There is also growing interest in utilizing humanoid robots like Valkyrie in manufacturing and other industrial settings . These strong and tireless automatons could take over dangerous, repetitive or physically demanding factory jobs.
Early trials using prototype humanoids for assembly line tasks have delivered promising results. Researchers are also exploring having robots collaborate side-by-side with human workers to combine strengths.
“This human-robot teaming approach is the ideal way to maximize productivity while retaining the creativity and problem-solving abilities unique to humans,” says industrial engineer Dr. Yasmin Merali.
There are still significant technical hurdles to address before widespread adoption of humanoid factory robots, most notably further improving motor coordination, dexterity and perception capabilities using the latest AI. But rapid progress suggests the robots are poised to march off the lab benches and onto factory floors within a decade.
Growing Pains on the Road to Robot Utopia
The increasing sophistication of AI-powered humanoid robots offers tantalizing promise, but also raises challenging questions about potentially profound societal impacts . If these strong, tireless and intelligent machines begin handling many jobs currently occupied by humans, mass unemployment could result. And further progress toward autonomous robots that match or exceed human-level intelligence faces ethical issues.
“There is understandable concern that as robots become more and more human-like in terms of physical and mental capabilities, an existential threat may emerge if safeguards are not put in place regarding how these machines operate,” cautions Arnold Zhang, a professor of robo-ethics at Stanford University.
But others argue the pending revolution in robotics will usher in a new age of abundance, with humanoid helpers tackling life’s drudgeries to free up time for leisure and creative pursuits. Striking the right balance to maximize benefits and minimize risks poses one of the key technological and policy challenges in the coming decades.
Outlook: Full Speed Ahead Despite Obstacles
The next decade promises to be the most transformative period yet for humanoid robots. Rapid advances in mechanical design, AI, computer vision and other supporting technologies will drive new breakthroughs. NASA’s Valkyrie and other prototypes are progressing quickly from the lab to real-world testing and validation.
Nearer-term applications such as emergency response, assisted living, manufacturing and hazardous environment exploration are leading the charge. Interest is also growing in directly integrating these intelligent machines into the workforce to bolster productivity.
Concerns around economic impacts and artificial general intelligence represent significant societal headwinds. But the momentum behind development efforts continues largely unabated, suggesting humanoids are poised to expand beyond niche domains and take up residence in our lives in the not-too-distant future.
