A new robotic system developed by researchers in the United States and the Middle East is designed to handle rescue missions by combining multiple machines into a single coordinated unit. Known as X1, the setup pairs a humanoid robot with a transformable drone, allowing it to walk, drive, and fly depending on the situation.
The project was led by engineers at California Institute of Technology in collaboration with Abu Dhabi’s Technology Innovation Institute. The system was demonstrated navigating indoor and outdoor environments, showing how different robots can work together as one coordinated team instead of operating independently, as reported by Earth.com.
At the center of X1 is a humanoid robot based on the Unitree G1 platform, capable of walking on two legs and carrying equipment across complex terrain. Mounted on its back is a second machine called M4, a morphing robot that can switch between different movement modes. It can operate as a drone, a wheeled rover, or a hybrid system depending on the environment.
During testing, the humanoid carried the M4 unit through buildings and across obstacles before deploying it in an open area. Once released, the smaller robot flew into the air, landed, transitioned into a wheeled mode, and continued moving across the ground. This ability to switch between movement types allows the system to adapt to changing conditions without human intervention.
The robots are equipped with sensors including cameras, lidar, and range finders, enabling them to navigate and map surroundings autonomously. Researchers used a combination of physics based models and machine learning to allow the system to adjust its movement in real time, particularly in environments where pre programmed actions would not be sufficient.
This type of coordination is known as a multi robot system, where each unit performs tasks suited to its strengths. The humanoid handles long distance movement and heavy loads, while the smaller robot focuses on exploration and rapid response in areas that require flight or precise maneuvering.
The system is being developed for use in disaster response scenarios, where conditions can change quickly and human access may be limited or dangerous. Potential applications include surveying damaged buildings, navigating flooded areas, and delivering supplies before rescue teams arrive.
For now, X1 operates using pre defined mission sequences, but researchers are working to improve reliability and safety. This includes ensuring the robots can handle sensor failures, avoid risky behavior, and maintain stable operation in unpredictable environments.
If the technology matures, systems like X1 could become part of future emergency response strategies, combining different forms of mobility into a single adaptable platform capable of operating where humans cannot.
