Smart fluidic circuits for autonomous soft robots

Project description

Facilitating soft robot technology

Soft robots have emerged in recent years, their main difference from traditional rigid robots being that they are inherently safer, more flexible and robust in use, making them easier to implement for human interaction. Unfortunately, soft robots also face difficulties, such as the fact that existing robot technologies are too bulky to be embedded or that they have very low power efficiency. The EU-funded FlowBot project will work to overcome these issues by developing soft fluidic circuits that can effectively power and control soft robots and their behaviour. The project will achieve this by implementing novel experimental standards as well as new computational approaches and design principles.


Soft robots have the potential to be more robust, adaptable, and safer for human interaction than traditional rigid robots. State-of-the-art developments push these soft robotic systems towards applications such as rehabilitation and diagnostic devices, exoskeletons for gait assistance, and grippers that can handle delicate objects. However, despite these exciting developments, there are two major challenges: (1) existing electronic control, intelligence and power of soft robots is too bulky to be embedded, and (2) the power efficiency of soft robots is extremely low. As a result, most existing soft robots still rely on tethers to deliver the required power and control.

To increase the application perspective of soft robots, I aim to ‘cut the tethers’, with the ultimate goal to realise fully autonomous and smart soft robots that can interact with humans and complex environments. To do so, I propose to replace electronics with embedded fluidic circuits in a three step approach. First, I aim to achieve intelligent behaviour in soft robots by embedding smart fluidic circuits, that have integrated fluidic sensors to allow for feedback with the environment. Then, I will close the fluidic circuit to be able to reuse elastic energy that is currently lost after each actuation cycle, to dramatically increase the efficiency of soft robots. Finally, I will embed a reliable pressure source based on chemical fuel regulated by soft fluidic circuits.

Taken together, I propose to develop new concepts to effectively power and control the behaviour of soft robots, and to achieve this I will develop new experimental standards, computational approaches, and generalise design principles. As a results, this research will pave the way for the first fully autonomous soft robots that are capable of operating for longer periods of time.
