A recent framework has been introduced to measure the versatility, efficiency, mode-switching capabilities, and overall performance improvements of multimodal robots. These bioinspired robots can seamlessly switch between various modes of movement, such as flying, walking, swimming, or climbing. Researchers are making significant strides in developing robots that can adapt to diverse environments by integrating multiple locomotion modes into a single machine. The framework aims to drive the development of advanced robots that are more capable, efficient, and adaptable.
Multimodal robots, capable of transitioning between different movement forms like walking, flying, swimming, climbing, or jumping, are rapidly evolving to mimic the agility and adaptability found in nature. A recent study conducted by researchers at Beihang University, Dalian University of Technology, and EPFL examines the progress of bioinspired multimodal robots, the engineering hurdles they face, and a new performance evaluation framework.
Unlike traditional robots that rely on a single movement mode, multimodal robots incorporate two or more locomotion methods on a single platform. These robots have evolved from using separate mechanisms to adopting integrated systems inspired by animals, enhancing adaptability and efficiency. The primary goal of multimodal robotics is to enhance overall performance in challenging environments by enabling robots to switch between various movement modes efficiently.
To make multimodal robots more viable, engineers must overcome several challenges such as limited onboard space, body morphing capabilities, and ensuring seamless integration of different locomotion modes. The researchers propose five performance metrics to evaluate these robots, measuring factors like the number of movement modes, additional costs, shared components, switching efficiency, and overall performance gains achieved.
In order to enhance future robots, innovative design strategies are being explored, including the use of soft materials, flexible structures, structure repurposing, and multirobot architecture. Advances in materials, actuators, sensors, and learning algorithms are seen as crucial in achieving seamless transitions and autonomous decision-making in complex environments. By tightly integrating adaptive hardware with AI-driven perception, planning, and control, the goal is to surpass the versatility of natural animals in some applications.
