Current-free circuit for robotics: Researchers have developed a system that uses pressure differences to transmit precise signals. This technology creates more space for the “brains” of robots and enables operations in harsh environments.
Pressure-controlled robots: innovation without electricity
Engineers at King's College London have developed a new circuit that can transmit complex commands to robots without electricity. The circuit uses pressure differences in the fluid to transmit signals, similar to how some parts of the human body work. This method allows instructions to be sent directly to robot devices.
The heart of the system is an adjustable diode that acts like a transistor in a conventional circuit. Changes in pressure can send signals similar to binary code. This allows robots to perform complex maneuvers without relying on instructions from a central “brain.”
The system differs significantly from conventional hydraulic systems. It uses pressure differences to accurately transmit binary signals, allowing better control and transmission of complex commands without electrical signals. The reconfigurable circuit is specifically designed for integration into robotic systems and can therefore take over tasks from the central “brain”.
doctor. Antonio Forte, lead author of Advanced Science. He studies (via TechXplorer), explains: “Software has evolved rapidly in recent years, but hardware hasn't been able to keep up. By creating a hardware system that's independent of the software it runs on, we can shift a lot of computing power to the hardware. Likewise, your brain doesn't have to tell “Your heart is beating.”
New technology opens up a wide range of possible uses. The robots can operate in radiation-contaminated areas where electrical circuits fail. Uses can also be envisioned in electrically sensitive environments such as MRI rooms or in countries with unreliable power supplies. The researchers plan to expand the technology to include larger robotic systems.
Without investment in embodied intelligence, robots will stagnate. Our work is just the first step on this path, but the future promises smarter robots with smarter bodies.
- Researchers are developing a system to transmit signals through pressure differences in robots
- The system provides more precise control of the body without central “brain” instructions
- The adjustable valve works like a transistor to control complex maneuvers
