Soft inflatable robots have emerged as a promising solution for applications that require both safety and adaptability. However, integrating sensing and control systems into these robots has been a challenge without compromising their soft and flexible nature. To address this issue, a collaborative research team led by Professor Jiyun Kim from the Department of New Material Engineering and Professor Jonbum Bae from the Department of Mechanical Engineering at UNIST (Ulsan National Institute of Science and Technology) has developed groundbreaking “soft valve” technology. This innovation provides an all-in-one solution by seamlessly integrating sensors and control valves while preserving the softness and form factor of these robots.
Traditionally, soft robots incorporated rigid electronic components for sensing purposes. However, the team’s research introduces a novel approach to overcome this limitation. They have created soft analogs of sensors and control valves that operate without electricity. These tube-shaped components serve a dual function: detecting external stimuli and precisely controlling movement using air pressure alone. By eliminating the need for electricity-dependent components, these all-soft valves enable safe operation underwater or in environments where electrical sparks may pose risks, while also reducing the overall weight of robotic systems. Additionally, each component is cost-effective, with an estimated cost of approximately 800 Korean Won.
Professor Kim explained the significance of their work, stating, “Previous soft robots had flexible bodies but relied on hard electronic parts for stimulus detection sensors and drive control units. Our study focuses on making both sensors and drive control parts using soft materials.”
The research team demonstrated various applications of this innovative technology. They developed universal tongs capable of delicately handling fragile items like potato chips, preventing breakage that can occur with conventional rigid robot hands. Additionally, they used these all-soft components to create wearable elbow assist robots designed to reduce muscle strain during repetitive or strenuous arm movements. The elbow support automatically adjusts according to the angle of the user’s arm, resulting in an average 63% reduction in elbow strain when wearing the robot.
The operation of the soft valve relies on the flow of air within a tube-shaped structure. When tension is applied to one end of the tube, a helically wound thread inside compresses it, thereby controlling the inflow and outflow of air. This accordion-like motion allows for precise and flexible movements without the need for electrical power.
Furthermore, the research team demonstrated that by programming different structures or numbers of threads within the tube, they could accurately control variations in airflow. This programmability enables customized adjustments to suit specific situations and requirements, providing flexibility in the response of the driving unit even when consistent external forces are applied to the end of the tube.
Professor Bae expressed excitement about this development, saying, “These newly developed components can be easily employed using material programming alone, eliminating the need for electronic devices. This breakthrough will significantly contribute to advancements in various wearable systems.”
This groundbreaking soft valve technology represents a significant step toward fully soft, electronics-free robots capable of autonomous operation, a crucial milestone for enhancing safety and adaptability across various industries. The research was supported by various organizations, including Korea’s National Research Foundation (NRF), Korea Institute of Materials Science (KIMS), and Korea Evaluation Institute of Industrial Technology.

The UK and Israel are set to sign an innovation and tech collaboration agreement aimed at fostering joint tech projects and advanced research areas, including quantum computing. The deal, which follows a meeting between science ministers in London, will involve a commitment of £1.7 million in support for collaborative tech initiatives. The agreement aligns with the UK’s broader objective of forming tech and innovation partnerships worldwide, similar to agreements reached with countries like India, Japan, Switzerland, and South Africa.
Israel is renowned for its innovation and startup ecosystem, with a strong emphasis on research and development (R&D). The collaboration with Israel spans three key areas: research, commercialization, and bilateral government priorities. Israel’s high R&D spending has contributed to a thriving technology landscape, producing successful startups such as website builder Wix and navigation app company Waze, which Google acquired in 2013.
George Freeman, the UK’s Minister for the Department for Science, Innovation, and Technology, emphasized Israel’s reputation as a global innovation hub and highlighted the significance of this collaboration in supporting the UK’s mission to become a science superpower.
Ofir Akunis of Israel’s Ministry of Innovation, Science, and Technology noted that the agreement would strengthen scientific and technological cooperation and networking between both countries, benefiting their scientific communities and broader economies.
This collaboration follows the UK’s recent agreement with the EU to participate in the Horizon Europe scientific research program, further demonstrating the country’s commitment to fostering international research and innovation partnerships.
Researchers have extended their earlier work on soft robots by creating a “brainless” version capable of navigating more complex and dynamic environments independently. The soft robot uses physical intelligence, relying on its structural design and material properties rather than computer or human guidance.
The soft robot is constructed from ribbon-like liquid crystal elastomers. When placed on a surface hotter than the ambient air, a portion of the ribbon in contact with the surface contracts while the exposed part does not, inducing a rolling motion. The warmer the surface, the faster the robot rolls.
However, unlike the previous symmetrical design, the new soft robot has an asymmetrical structure with two distinct halves. One half resembles a twisted ribbon extending in a straight line, while the other half is more tightly twisted and spirals around itself.
The asymmetry of the design allows one end of the robot to exert more force on the ground than the other, causing the robot to turn without requiring contact with an object. This capability enables it to navigate twisty mazes and negotiate its way around moving obstacles without getting stuck between parallel objects.
The researchers demonstrated the robot’s ability to navigate complex mazes, including those with moving walls, and to fit through narrow spaces narrower than its body size. The robot was tested on both a metal surface and in sand.
The development of this asymmetrical soft robot design represents progress in soft robot design, particularly for applications where such robots can harness heat energy from their environment, offering potential for innovative applications.
