Cats’ Eyes and How They Are Inspiring New Robotics Technologies.

Previously, we discussed how cats’ brains have influenced supercomputer designs. Now, researchers are looking at their eyes to shape the future of robotics. A recent breakthrough has seen scientists develop an artificial vision system inspired by cats. This biomimicry innovation enables robots to detect and track objects in challenging environments, which could revolutionise autonomous systems.

What is an Autonomous System?

An autonomous system is a technology that operates independently, making decisions and performing tasks without human intervention. These systems rely on sensors, artificial intelligence, and machine learning algorithms. In robotics, autonomous systems can navigate and detect objects, adapting to real-time data. For example, self-driving cars are autonomous systems, as they navigate, detect obstacles, and follow traffic rules independently. By incorporating biomimicry like cat-inspired vision, autonomous systems gain advanced capabilities for complex, real-world scenarios.

How Cats See in the Dark

Ever wondered how cats navigate so well in the dark? Their eyes are masterworks of evolution, adapted to excel in low-light conditions. This ability stems from two key features:

  1. Tapetum Lucidum: This reflective layer behind the retina boosts low-light vision by reflecting light back through the retina, giving cats a “second chance” to absorb it. This is also why their eyes seem to glow in the dark.
  2. Vertically Slit Pupils: Cats’ pupils adjust rapidly to different lighting. Their vertical slits help them control light intake, essential for their dawn and dusk hunting habits.

Inspired by these traits, researchers designed a new artificial vision system for robotics. By mimicking cats’ reflective tapetum lucidum and elongated pupils, this system enhances object detection and tracking capabilities. This reduces energy consumption and computational load, making it ideal for autonomous vehicles, surveillance, and other applications in challenging environments.

The Power of Biomimicry: Nature’s Innovations, Human Solutions

Biomimicry taps into nature’s best ideas to solve human challenges. Here are more incredible examples:

  • Velcro: Inspired by burrs that stick to animal fur, Velcro has become a staple in various industries, from clothing to space exploration.
  • Sharkskin: The texture of shark skin reduces drag, inspiring advancements in swimwear and airplane wing design.
  • The Lotus Effect: Mimicking lotus leaves’ self-cleaning abilities, this has led to waterproof fabrics and coatings for clothing and building materials.
  • Gecko Feet: The adhesive properties of gecko feet, which allow them to climb without sticky residue, have inspired new dry adhesives and climbing robots.

Each of these innovations, including cat-inspired vision systems, echoes a message from Rockford’s Rock Opera: “Every creature has a secret.” As species face extinction, we risk losing invaluable designs that could inspire future technologies.

Why Biomimicry Matters for a Sustainable Future

Biomimicry holds the key to innovation and sustainability. By mimicking adaptations honed over millennia, we can create efficient, environmentally-friendly technologies. Biomimicry reduces resource consumption, cuts waste, and builds resilience, crucial in combating climate change.

Celebrating Nature’s Design

As we deepen our understanding of the natural world, our capacity for innovation grows. The more we uncover the hidden secrets of nature, the more we unlock new ways to tackle complex challenges. Biomimicry, from cat-inspired vision to potential future discoveries, offers a path to a more sustainable, inventive world.
