Snail-Inspired Robots Use Swarm Power to Climb and Collaborate

A team of researchers has developed snail-inspired robots capable of traversing rough terrain, climbing vertical surfaces, and working together to overcome obstacles.

Modelled after white jade land snails, the robots use a dual-mode system to switch between independent movement and collaborative climbing. In free mode, they move using lightweight rubber tracks. In strong mode, they activate a vacuum-style sucker to attach to each other and navigate more complex environments.

The robots also feature magnetic adhesion, allowing them to connect at multiple points to the iron shells of other robots. This design mimics the mucus adhesion and suction force of real snails, enabling the swarm to form bridges and cross ditches.

Unlike traditional swarm robots, which typically connect at a single point, these snail robots can form multi-point connections. This enhances their ability to function as a group while retaining individual mobility.

The researchers suggest potential applications in search and rescue operations and environmental monitoring, where navigating unpredictable terrain is essential.

The study was published in Nature Communications.
