Robot Cat Takes Inspiration From Nature


Oftentimes, a project starts with a clean sheet of paper, and we set out wildly sketching towards the goal in our minds. However, it can pay to do your research first, as [Chen Liang] demonstrates with this great robotic cat build.

[Liang] began the project after being dissatisfied with existing robot animals they’d seen online. Rather than simply attempt to build a cat from memory, instead, [Liang] decided to first study a real cat to ensure the resulting robot would bear real resemblence to its biological inspiration. [Liang]’s focus was on the skeleton, as replicating the way the real skeleton worked would create a robot with more authentic movement.

Using 3D printed parts and many, many servos, we think [Liang] has done an admirable job at creating a basic robot cat platform. With an ESP32 running the show, the cat can be posed using a web interface to control the servo positions of its various joints. We look forward to future upgrades that enable fluid movement and other capabilities, particularly involving the onboard camera.

It’s not the first robot cat we’ve seen, and it’s likely it won’t be the last. If you’ve got one living in your own lab, drop us a note on the tipline. Video after the break.
