The Future of Modular Robotics: EPFL’s Mori3, the Polygon Meshing Robot

      

Swarm behavior from the biological world and polygon meshing from the digital sphere come together to inspire the creation of the Mori3 robot, a breakthrough in the realm of modular robotics. This novel invention developed by researchers at EPFL exhibits the potential of morphing from 2D triangles into virtually any 3D object, heralding a significant promise for space travel applications. The research, recently published in Nature Machine Intelligence, paints an exciting picture for the future of robotics.

“Our aim with Mori3 is to create a modular, origami-like robot that can be assembled and disassembled at will depending on the environment and task at hand,” says Jamie Paik, director of the Reconfigurable Robotics Lab. She continues, “Mori3 can change its size, shape, and function.”

Understanding the Mori3 Robot: The Power of Polygon Meshing

The Mori3 robot consists of individual modules, each triangular in shape. These modules seamlessly link to form polygons of varying sizes and configurations, a procedure known as polygon meshing. Christoph Belke, a post-doctoral researcher in robotics, comments, “We have shown that polygon meshing is a viable robotic strategy.”

Achieving this breakthrough required pushing the boundaries of multiple robotics aspects, including mechanical and electronic design, computer systems, and engineering. “We had to rethink the way we understand robotics,” explains Belke. “These robots can change their own shape, attach to each other, communicate, and reconfigure to form functional and articulated structures.” The proof of concept is seen as a success as Mori3 robots demonstrate proficiency in key robotic abilities: mobility, handling and transporting objects, and user interaction.

Space Exploration: A New Frontier for Modular Robots

Modular and multifunctional robots like Mori3 bring significant advantages, especially when it comes to performing a broad array of tasks, which often necessitate changes in shape or configuration. Paik explains, “Polygonal and polymorphic robots that connect to one another to create articulated structures can be used effectively for a variety of applications.”

She also acknowledges that a general-purpose robot like Mori3 may be less effective than specialized robots in certain domains. “That said, Mori3’s biggest selling point is its versatility,” Paik points out. The designers envisage Mori3 robots being utilized in spacecraft, which lack the space to house different robots for each individual task. The researchers harbor hopes of seeing Mori3 robots used for communication purposes and external repairs in space missions.

An Innovative Leap in Robotics

The development of Mori3 signals a monumental shift in the robotics field, showcasing the possibilities that lie ahead in modular robotics. The unique blend of digital and biological inspiration has given birth to a robot that can change its form and function according to the task and environment, a feature that holds enormous potential, particularly in space exploration.

However, as the technology progresses, it will be important to ensure that the capabilities of such versatile robots are optimized, and their potential drawbacks carefully managed. This innovative leap in robotics opens up a plethora of opportunities and questions, making it a riveting field to watch in the coming years. As Mori3 paves the way, we can look forward to seeing how this pioneering technology will transform the way we approach robotics and space exploration.
