Amazing Advancements in Soft Robotics

Soft robotics represents a groundbreaking advancement in the field, standing apart from the rigid structures people usually associate with traditional robotic systems. Learn more about recent advances in this field and the many benefits.

The Era of Soft Robots

Nature and biology heavily influence soft robots, giving them the flexibility and ability to adapt to their surroundings. For example, some commercially available soft robotic designs mimic fish, octopi and worms.

Innovative materials such as shape-memory alloys, dielectric elastomers and liquid crystal elastomers are critical to soft robotics. These materials change their properties in response to various stimuli. Grippers on soft robots, made of high-tech elastomers, mold to the target object’s shape. This flexibility ensures a gentler and more adaptable grip than rigid robots, making them ideal for tasks like fruit picking. 

Soft robots also use self-healing materials made from shape-memory alloys. These alloys allow the robots to repair themselves after damage, increasing their operational life span and reducing maintenance needs.

As technology progresses, scientists outfit soft robots with sensory systems, enhancing their ability to understand their surroundings. For example, soft pressure sensors can tell a robot if it’s gripping too hard. Some researchers are even developing soft robots capable of working in swarms, emulating the behavior of fish, bees and birds. 

3D printing, a form of advanced manufacturing, has revolutionized how scientists design and produce intricate soft robotic parts, driving innovation and accessibility in this sector. Some robots incorporate the strengths of both rigid and soft systems, resulting in hybrids that offer improved strength, precision and flexibility. Instead of traditional motors, there’s a growing trend towards fluidic actuation. Robots use liquids or air for movement, making their movements more natural. 

Soft Robotics in Medicine

Robotics is revolutionizing various aspects of modern medicine. In rehabilitation and physiotherapy, soft robotic exosuits or exoskeletons support patients recovering from strokes, spinal cord injuries or surgeries. These devices gently guide and assist patients, helping them regain motor functions, relearn movements and restore strength.

In assistive medical devices, soft wearable robots are emerging to help those with mobility issues. The Wyss Institute at Harvard University developed a soft, wearable robotic glove that assists individuals with hand disabilities in performing day-to-day activities. This glove, made from soft elastomers, can assist in gripping objects, potentially improving rehabilitation outcomes.

Scientists at the City University of Hong Kong developed a soft robot capable of maneuvering inside the stomach and intestine. The robot can change shape and size, facilitating better imaging and allowing localized drug delivery or biopsies.

A collaboration between Boston Children’s Hospital and Harvard University resulted in a soft robotic sleeve that surgeons can place around the heart. This device helps the heart pump more efficiently in patients with heart failure, providing a potential alternative to organ transplants.

In diagnostics, soft robots simplify procedures like endoscopy, making it less invasive and patient-friendly. Patients can now swallow endoscopy capsules equipped with a camera and a tissue collection mechanism to get the same results traditionally obtained by putting patients under general anesthesia. 

Research teams at institutes like the Sant’Anna School of Advanced Studies in Italy have been working on developing soft robotic arms that can assist surgeons. Due to their soft and pliant design, these arms can navigate the body with minimal risk of damaging tissues or organs.

Soft Robotics in Marine Conservation

Equipped with sensors, soft robots can monitor water quality, track marine species and evaluate the health of habitats over prolonged periods. Their non-intrusive nature and versatility enable them to probe areas inaccessible to traditional robots. MIT’s Computer Science and Artificial Intelligence Laboratory developed a soft robotic fish named „SoFi“ that can swim naturally in the ocean, recording close-up videos of marine life and providing insights without alarming or disturbing the aquatic life.

Soft robots also offer the potential for marine clean-up efforts, such as removing pollutants like microplastics and oil spills. The WasteShark, developed by RanMarine Technology, is an ASV designed to „eat“ or collect trash in harbors and other waters close to the shore. This drone skims the water’s surface, collecting waste in its path, thereby aiding in marine clean-up.

The Ocean Exploration Trust’s E/V Nautilus expeditions have been using ROVs to explore and map uncharted coral reefs, helping scientists understand their structures, the species they harbor and their overall health. Similar soft robots can be deployed to plant sea grass and maintain coral reefs. 

ROVs like the Hercules, also from the E/V Nautilus expedition, have robotic arms that can collect geological and biological samples from the deep sea that can help scientists study ecosystems in abyssal regions, leading to new species discoveries and insights into deep-sea conservation needs.

The Challenges Ahead

Soft robotics faces challenges, but its vast potential is undeniable. A primary focus lies in developing innovative materials that combine durability, flexibility and responsiveness. While traditional actuators, like motors, aren’t suitable for soft robots, alternatives like pneumatic and hydraulic systems are on the rise, promising unparalleled autonomy.

Manufacturing these robots at scale is now more feasible due to advanced construction techniques and materials. Even as these robots retain flexibility, integrating crucial rigid components, like batteries, is becoming smoother. The scientific community aims to enhance the response times of soft actuation mechanisms to match or exceed traditional systems.

Safety remains a top priority in soft robotics, especially in applications involving humans or medical scenarios. Although the field recognizes the higher initial research and production costs, they believe ongoing advancements will reduce expenses.

Artificial feathers give flight to robotic birds

Festo presents its new bionic project “BionicSwift”


Thanks to radio-based indoor GPS with ultra-wideband technology (UWB) the BionicSwifts can fly safely and in a coordinated pattern in a defined airspace. To execute these flight manoeuvres as true to life as possible, the wings are modelled on the plumage of real birds. The agility of the artificial birds is not just due to their lightweight design and aerodynamic kinematics, but also to the use of function integration.


The Festo Bionic Learning Network has a long tradition of being inspired by natural flight. The creation of the BionicSwift represents the next chapter for Festo in the development of bionic flying objects. As in its biological model, the use of lightweight structures is at the heart of the artificial bird. Because in both engineering and in nature, the less weight there is to move, the less material is required, and the less energy is consumed. That is why the BionicSwift weighs just 42 grams despite having a body length of 44.5 centimetres and a wingspan of 68 centimetres. This makes it extremely agile, nimble and capable of flying loops and making tight turns. By interacting with a radio-based indoor navigation system, the robotic birds are able to move autonomously in a coordinated pattern in a defined airspace.

Aerodynamic feathers

To be able to replicate natural flight as closely as possible, the wings of the BionicSwifts are modelled on bird feathers. The individual lamellae are made from an ultra-lightweight, flexible but very robust foam, and overlap each other. Connected to a carbon quill, they are attached to the actual hand and arm wings as in the natural model. The individual lamellae fan out during the wing upstroke, allowing air to flow through the wing. This means the birds require less power to propel the wing upwards. The lamellae then close during the downstroke to provide the flying robot with a more powerful flight. This close replication of bird wings gives the BionicSwift a better flight profile than previous beating wing drives.

Function integration in the tightest of spaces

The agility of the artificial bird is not just due to its lightweight design and aerodynamic kinematics, but also to the use of function integration. The bird’s body contains the compact construction for the wingflapping mechanism, the communication technology, the control components for wing flapping and the elevator, the tail. A brushless motor, two servo motors, the battery, the gear unit and various circuit boards are installed in the smallest of spaces. Through the intelligent interaction of the motors and mechanical systems, the frequency of the wing beats and the elevator for the various manoeuvres can be precisely adjusted.

GPS coordination of the flight manoeuvre

The coordinated and safe flight of the robotic birds is made possible by radio-based indoor GPS with ultra-wideband technology (UWB). Several radio modules are mounted in the space, forming fixed anchors that locate each other and define the controlled airspace. Each bird is equipped with a radio marker that sends signals to the bases, which can then locate the bird’s exact position and send the data collected to a central master computer, which functions as a navigation system. The system can use preprogrammed paths to plan and determine routes and flight paths for the birds. If the birds deviate from this flight path, for example due to a sudden change in ambient conditions such as wind or thermals, they immediate correct their flight path by intervening autonomously – without any human pilots. Radio-based communication means that position sensing is possible, even if there are obstacles and visual contact is partially lost. The use of UWB as radio technology guarantees safe and interference-free operation.

New inspiration for intralogistics

The intelligent networking of flight objects and GPS routing makes a 3D navigation system that could be used in the networked factory of the future. For example, by precisely locating the flow of materials and goods, process workflows can be improved and bottlenecks can be predicted. In addition, autonomous flying robots could be used for transporting materials, with their flight corridors a way of optimising the use of space within a factory.

Bionic Flower: a bionically inspired robot flower

Another step for the integral didactic concept of Bionics4Education

Festo Didactic presents a new product for the bionics didactic concept of Bionics4Education. What is new: the orientation towards the maker movement approach and the 4Cs. The aim is inspiring learners, finding new ways and solutions, dealing creatively with provided materials, and sharing these experiences with others to prepare them for the digital world of tomorrow.

Inspired by the plant world

The Bionic Flower is a construction kit inspired by the plant world. Festo Didactic developed the Bionic Flower following the models of mimosa plants and water lilies in cooperation with SkySpirit. The Bionic Flower opens and closes its petals as a reaction to external influences such as touch, proximity or light. These mechanisms can be discovered in a playful way by pupils in the classroom using sensors and control technology integrated in the Bionic Flower. The design, as well as the transfer of principles from the plant world, rounds off the teaching of curriculum topics in STEM education (Science, Technology, Engineering, and Maths). The topic of biodiversity can also be discussed in class.

Bionic work didactically prepared

One Bionic Flower can be used by up to three students at a recommended age of 10 and over. The petals contain the first bionic topic: the folding technique. The petals gain the necessary mechanical stiffness by folding. The mechanism for opening and closing the petals is electrically actuated with a stepper motor which opens and closes the petals one after the other. The movement and the light effects are controlled via Wi-Fi-enabled smartphones, tablets or PCs. If required, the microcontroller can be programmed with the graphic coding interface „Open Roberta“. Experienced students can also program their Bionic Flower in C++. The code is open source. This enables teachers to teach technical content via a new, interdisciplinary educational path. Accompanying teaching material, as well as the assembly manual, can be downloaded free of charge from our website www.bionics4education.com.

An expanded approach to promoting valuable skills

Students learn different aspects of STEM with the Bionic Flower – in a digital, creative and interdisciplinary way. The Bionic Flower combines bionics and technical education and is thus based on the competencies of the 4Cs: collaboration, communication, critical thinking and creativity to empower learners for the digital world of tomorrow.
In addition, soft skills such as working in a team are reinforced.

New in the concept: the maker movement approach

The maker movement is based on the DIY (do it yourself) culture and the idea of finding new ways and solutions, dealing creatively with materials, and sharing these experiences with others. The Bionic Flower takes this approach and combines Maker Education and STEM Education. In addition to assembling the Bionic Flower, learners can customize and expand on the Bionic Flower by using 3D printers, other materials, hardware and software.
