The new pressure controlled system developed at King’s College London is changing how robots move and think — without using electricity. As robots take on more complex tasks, the demand for advanced AI and autonomy grows. Traditional robots depend on electric power for both movement and decision-making, but this first-of-its-kind pressure-based robotic control system frees up space inside the robot for computing purposes, enabling more sophisticated AI-driven performance.
These novel systems promise more adaptive, versatile robots that can truly thrive in low-power or electricity-sensitive environments, ranging from medical facilities to exploration sites in remote areas.
The new pressure controlled system from King’s College London sends instructions to the robotic system through fluid pressure instead of electrical currents. In one setup that closely resembles certain mechanisms of the human body, commands are directed to the hardware of a robot through fluctuations in fluid pressure via a tightly packed circuit. This innovative approach opens up new possibilities for autonomous robots, free from a central control unit, allowing the space in their “brain” to be used for more complex AI-driven functions.
According to Dr. Antonio Forte, a senior lecturer in engineering at King’s College London, this innovation is the task of “delegating tasks to different parts of the body” so that robots can think and react on their own in a particular environment. This is revolutionary for sectors requiring more advanced robotic functionality with very low power consumption, including social care, manufacturing, and environmental monitoring.
How the New Pressure Controlled System Empowers Smarter Robots
Traditionally, robots have had two parts:
- The Brain: A central module powered by algorithms and software that processes information.
- The Body: All the hardware that executes whatever commands have been received through the brain.
This new pressure controlled system allows engineers to offload control to the body itself, reducing the computational loads on the central “brain” and opening up space for complex AI functions. The design lowers the need for electricity and makes robots capable of operations previously unimaginable.
Dr. Forte explains, “in putting the computational load onto the hardware itself, [robots] can enact ever more complex, adaptive behaviors.” This innovation also satisfies one of the visions pursued in soft robotics — to achieve increasingly lifelike robots with flexible, responsive structures that approximate muscles.
This newly designed pressure controlled system from King’s College London has a wide scope of application in various fields, especially in low-power and specialized environments where conventional robots are limited.

Hazardous Environment Exploration
In the presence of ionizing radiation — for example, in the case of Chernobyl or any other radiating region — this new pressure controlled system might be a better contender for safer and more consistent performance. Ionizing radiation destroys electronic circuits, rendering robots useless. The entire system will remain intact with no use of electricity.
Medical Facilities and Electric-Sensitive Environments
The limitation in such places arises where MRI machines and other electric-sensitive equipment function. A non-electric robot can safely be used close to such apparatuses, making it possible to provide aid in subtle tasks in a strict sterile environment. Applications in robotic-assisted surgery could include using pressure-based robots to enable procedures that are otherwise precluded by electronic interference.
Robotics in Low-Resource Settings
A pressure controlled system could unlock robotic applications in low-income and rural areas where electricity is unreliable. The system can support various services — from agricultural assistance to healthcare delivery in underserved communities — tapping into the potential of robotics where reliable power sources are not feasible.
How Pressure-Based Circuits Work: A Leap Forward in Robotic Hardware
Traditionally, hard electronic encoders in robots translate commands from the central processor to the hardware. This setup strains both the hardware and software. The pressure-based circuit, on the other hand, works on a concept called a reconfigurable circuit with a variable valve that works identically to a transistor on an electrical circuit.
This circuit passes orders to hardware by using pressure differences, so that instructions are translated into action with the aid of binary codes. The new pressure controlled system also allows more control than the fluid-based circuits currently in use, enabling the robot to execute more complex and accurate movements without central processing. The system was already tested and proven through lab prototypes and could be scaled up for complex machines used in monitoring power plants or performing tasks in disaster zones.
Future Directions: Smarter Robots with Independent “Brains” and “Bodies”
This successful pressure controlled system marks a new era of evolution. According to postgraduate researcher and co-author Mostafa Mousa, embodied intelligence will define the future of robotics. If robotic bodies start carrying out more functionality on their own, there will be less input required from central algorithms. This would result in much faster response times and an increased capacity to adapt to changing conditions.
Future development will take the technology to softer engines and more complicated crawler robots for delicate and dangerous monitoring tasks. More “intelligent” robots could make use of hardware for decision-making while allowing software to handle higher-order functions like social awareness and environmental adaptation.
This pioneering new pressure controlled system, developed at King’s College London, offers a glimpse of a future wherein robots can think, learn, and execute advanced functions without electricity. It could open up completely new possibilities in healthcare, environmental monitoring, and low-resource settings.
This technology will lead us to a world of flexible, low-power robots capable of working in any environment, thinking autonomously, and allowing for widespread applications — from social care to hazardous material handling. The next generation of robots will be smarter, more resilient, and more responsive to an ever-changing world.
