Researchers have developed 3D-printed robots that move using pneumatic pressure, eliminating the need for electronics and complex mechanisms, instead relying on a network of valves and compressed air to control soft actuators and enable walking motion. 

Here's a more detailed look at these electronics-free, 3D-printed pneumatic robots:

• How they work:

  Instead of motors or electronic controls, these robots use a network of valves and compressed air to inflate and deflate soft actuators, which are essentially inflatable chambers, causing the robot to move.

Generative AI is experimental.

3D-printed pneumatic logic modules:

Researchers at the University of Freiburg have developed 3D-printed pneumatic logic modules that can control the movements of soft robots using air pressure alone, enabling logical switching of air flow and mimicking electrical control. 

Walking robots:

One notable example is a six-legged walking robot that operates entirely without electronic components and is produced in a single 3D printing process. 

Applications:

These robots have potential applications in various fields, including soft robotics, and could be used for tasks that require flexibility and adaptability. 

Open Source Designs:

Many of these designs are open source, allowing anyone with a 3D printer to build and modify them. 

Examples:

• A robotic walker controlled by an integrated circuit using air pressure. 

An electronics-free drinks dispenser. 

A 3D-printed robotic gripper that autonomously detects, holds, and releases objects. 

Key Features:

• Electronics-free: The robots are powered by compressed air and pneumatic control circuits, eliminating the need for electronics. 

Soft Actuators: The robots use soft actuators that are inflated and deflated by air pressure to create movement. 

3D-Printable: The robots and their components, including the pneumatic logic modules, can be 3D-printed using conventional filament printing materials. 

Resilience: Some of these robots have been tested for resilience, demonstrating their ability to withstand loads and impacts.
