MUWA: The Ring-Shaped Robot That Can Fly, Stand, and Roll

"This innovative robot uses variable pitch propellers to navigate diverse terrains and environments, offering a new solution for disaster rescue and information gathering."


In disaster scenarios, the ability to navigate complex environments is critical. While traditional robots have limitations, multi-rotor flying robots, especially quadcopters, offer a promising solution due to their aerial maneuverability. However, these robots often struggle with narrow spaces and energy consumption.

Researchers have been exploring hybrid designs that combine flying capabilities with ground movement. However, the challenge remains: how to create a versatile robot that can overcome obstacles, conserve energy, and access confined areas?

This is where MUWA comes in. MUWA, short for Multi-field Universal Wheel for Air-land Vehicle, is a novel ring-shaped flying robot equipped with variable pitch propellers. This unique design allows it to not only fly but also stand, roll, and move on water, opening up new possibilities for disaster rescue and information gathering.

How MUWA's Design Enables Multi-Terrain Mobility

MUWA's ring-shaped body and variable pitch propellers are key to its versatility. Unlike traditional quadcopters that require a minimum horizontal area for their rotors, MUWA's ring shape allows it to fit through narrow vertical gaps and navigate complex terrain.

Here's how MUWA achieves its diverse range of motion:

  • Variable Pitch Propellers: These propellers can generate thrust in both directions, allowing for agile flight and even inverted maneuvers.
  • Ring-Shaped Body: The ring acts as a wheel, enabling MUWA to roll along the ground at any angle. It also provides buoyancy for water traversal.
  • Mono-Wheel Mode: By coordinating the propellers, MUWA can stand upright and maintain balance, even on uneven surfaces.
This combination of features allows MUWA to overcome limitations of traditional flying robots. It can navigate narrow gaps, conserve energy by rolling instead of flying, and access areas that would be impossible for other robots to reach.

The Future of Multi-Terrain Robotics with MUWA

MUWA represents a significant step forward in the development of multi-terrain robots. Its unique design and versatile capabilities make it a promising tool for disaster rescue, information gathering, and other applications where mobility is paramount.

While the current prototype has some limitations, such as limited rolling torque and lack of waterproofing, future iterations will address these challenges. Researchers are also working on incorporating sensors and autonomous control to further enhance MUWA's capabilities.

With ongoing development, MUWA has the potential to revolutionize how we approach robotics in complex and challenging environments, paving the way for safer and more effective disaster response efforts.
