The concept of embodied intelligence, stemming from philosophy and psychology, is revolutionizing robotics. This theory posits that intelligent behavior arises from the physical interaction between a body and its surroundings.It suggests that control isn’t solely dictated by a central “mind” but is distributed throughout the body and its interactions.

For engineers developing robots, this means moving beyond the traditional approach of simply attaching a sophisticated computer to a basic mechanical frame. According to researchers, true robotic intelligence requires a more integrated design where the physical form actively contributes to the robot’s capabilities.

the Future of Intelligent Robots: soft Robotics and Physical Control

One promising avenue is the development of soft robots, inspired by primitive and aquatic organisms. These robots, constructed from flexible materials, can leverage physical principles for control, sometimes eliminating the need for digital microcontrollers altogether. Instead, they exploit the non-linear physical properties of soft materials to generate control signals that drive movement.

“If we want a truly intelligent robot, we can’t just build a body consisting of two or three metal bars and a few joints, then put a very intelligent computer inside it.”

A recent article in Science Robotics, co-authored with researchers from Stuttgart, the netherlands, and Belgium, introduces the concept of “physical control” in soft robots. The research identifies three key control mechanisms that enable these robots to function.

One example highlighted in the study involves robots with self-oscillating valves. These valves,when subjected to air pressure,automatically open and close,creating rhythmic pressure fluctuations. This rhythmic signal then controls the movement of different parts of the robot.

Balancing Software and Physical Design

The future of robotics likely lies in a balanced approach. While software and microcontrollers will remain essential, significant advancements can be achieved through improved robot body design. By integrating physical control mechanisms, robots can become more adaptable, efficient, and intelligent.
