In the realm of space construction, NASA is ushering in a new era with its cutting-edge robotic, self-assembling structures. As humanity’s aspirations to colonize the moon and Mars grow stronger, the challenge of providing housing in these extraterrestrial environments becomes increasingly evident. Fortunately, NASA is at the forefront of innovative solutions, unveiling a self-assembling robotic structure that could play a pivotal role in our off-planet endeavors.
Recently published in Science Robotics, a paper from NASA’s Ames Research Center introduces the concept of “self-reprogrammable mechanical metamaterials.” In simpler terms, this technology embodies the idea of a building that constructs itself, aptly named “Automated Reconfigurable Mission Adaptive Digital Assembly Systems” or ARMADAS.
Christine Gregg, the lead author of the study, envisions a wide range of applications for this groundbreaking construction technology. In the near term, its robust autonomy and lightweight design prove invaluable in austere environments like the lunar surface or outer space. This includes the construction of communication towers and shelters on the moon, as well as the assembly of on-orbit structures such as booms and antennas, all before astronauts arrive at their destinations.
The ingenious concept behind these self-building structures revolves around the use of cuboctahedral frames, referred to as voxels, and two types of robots tasked with their assembly. One type of robot, resembling kinesin transport molecules in our biology, traverses the surface on two legs, carrying a voxel like a backpack. Once in position, a fastening robot, residing within the frame itself, secures the reversible attachment points. Remarkably, these robots do not require sophisticated sensing systems, and their collaborative effort ensures precision without the need for excessive accuracy.
The design of the voxels allows for attachment at various angles while maintaining structural integrity, making them ideal as a foundational base for adding insulation and sealant to create livable habitats. Kenneth Cheung, a co-author of the study, emphasizes the suitability of this construction approach for long-term projects and large infrastructure development, including habitats, instrumentation, or utility towers on the moon or in orbit. The versatility of these structures and robotic systems opens up possibilities for optimization over time and space.
Notably, the voxels themselves can potentially be manufactured from locally sourced materials on celestial bodies like the moon, reducing the need for transportation of construction materials from Earth. This aligns with NASA’s sustainability goals for future space missions.
While the videos of the robots in action may be accelerated, the pace of construction in space or on another planet does not demand lightning speed. The key to increasing the system’s speed and scalability lies in deploying more robots and optimizing algorithms for planning, scheduling, fault detection, and repairs.
In a remarkable demonstration, the lab’s robots assembled 256 voxels into a shelter structure in just 4.2 days. Scaling up, if these robots were dispatched a year ahead of a crew to Mars or the moon, they could potentially construct even larger structures, affix necessary plating, and seal them, expanding the possibilities of off-world habitation.
Regarding power supply, the robots are being designed with battery operation or on-site power sources in mind. Recharging stations and wireless power transfer are among the considerations, presenting promising solutions for sustaining their operations in distant locales.
Furthermore, these robots have already demonstrated their capabilities in space and microgravity environments, indicating their adaptability beyond Earth’s gravity. NASA’s exploration of swarms of robots for more complex structures is on the horizon, as the potential for larger projects sparks interest. While a basic shelter may require two walkers over four days, the future may hold even grander ambitions with the assistance of these tireless robotic companions. In space construction, many hands—or in this case, robotic ones—indeed make light work.
Conclusion:
NASA’s self-assembling robotic structures represent a game-changing advancement in space construction. With the potential to construct vital infrastructure on the moon and in space, this technology opens up new opportunities for market expansion. Companies specializing in space exploration and construction should closely monitor these developments and explore potential collaborations with NASA to capitalize on the growing demand for extraterrestrial habitats and infrastructure.
