Late last year, in Pasadena, California, a robot named X1 walked across the California Institute of Technology (Caltech) campus. This robot carried a second robot on its back. The X1 system was designed for tasks that are too dangerous for humans.
Engineers from Caltech and Abu Dhabi’s Technology Innovation Institute (TII) developed this robot duo as part of a three-year project. Each robot has a specific role, working together as a team.
The project is led by Aaron Ames, who focuses on robots that operate without direct human commands. The primary robot in the X1 system is a modified humanoid robot that can walk and carry heavy equipment. The second robot, called M4, can change shape to fit different tasks.
During a demonstration, the X1 system moved from a lab through a library and outside. The humanoid robot lifted M4 into the air as a drone. After completing its mission over a pond, M4 landed and returned to its carrying position.
Researchers highlight that X1 can adapt its movements to different challenges, like stairs or rough terrain. They aim to ensure that when robots like X1 are used in emergencies, they can make safe decisions on their own. The team hopes to show that these robots can be trusted in disaster situations, providing help without risking human lives.
