Metin Sitti is the Director of the Physical Intelligence Department at the Max Planck Institute for Intelligent Systems in Stuttgart, which he founded in 2014. He is also a Professor in the Department of Information Technology and Electrical Engineering at ETH Zurich, [1] a Professor at the School of Medicine and College of Engineering at Koç University [2] and co-founder of Setex Technologies Inc. based in Pittsburgh, USA.
Metin Sitti is a pioneer in wireless tiny medical robots, gecko-inspired adhesives, and bio-inspired miniature robots. His group, called the Physical Intelligence Department, strives to understand the principles of design, locomotion, control, perception, and learning of small-scale mobile robots. [3] Sitti and his team aim to encode intelligence (e.g., sensing, actuation, control, memory, logic, computation, adaptation, learning and decision-making capabilities) into robots. They use smart stimuli-responsive materials, structures and mechanisms to encode intelligence into the physical body of a robot. [4]
There is intelligence through brain power – neurons gathering and transmitting electrochemical signals that make a human, an animal or insect think. But there's another form of intelligence, and that is through the way the body is built. A gecko has feet that helps it stick to practically any surface, making his structure intelligent as it helps it survive in nature. Physical Intelligence means the hardware is smart, not just the software embedded in the brain.
Metin Sitti and his team's research ranges from small to milli- to microscale. Some robots are so tiny they have the size of a hair. Obviously, you can't add much hardware to such a small robot, so you have to be able to steer them around from outside, remotely. Magnetic, acoustic or light energy is the external force at play. Another way is using for instance live bacteria or algae to hook onto the robot – like a horse pulling a cart – to propel the robot forward. But how to control the bacteria which has a mind of its own? This is where biological engineering takes place where the bacteria is engineered in such a way that it is very fast in moving around, or senses specific things like a tumor.
The science in the Physical Intelligence Department is structured into three research thrusts. First, there is the Advanced Materials thrust where the researchers develop new bio-inspired, biological or synthetic materials for encoding physical intelligence into small-scale robots. As an example, his team designs, manufactures and applies gecko foot-hairs-inspired elastomer microfiber adhesives for controlled gripping, adhesion/friction, and liquid wetting of robot bodies or grippers and wearable soft sensors. Another example are self-healing and multifunctional protein materials, shape-programmable and multifunctional soft magnetic composites, stimuli-responsive liquid crystal elastomers and hydrogels, functional micro/nanomaterials, patient-derived biomaterials, and light-driven photocatalytic and liquid crystal materials for miniature soft robot actuation, propulsion, sensing, control, and physical adaptation.
Second, there is the Mobile Millirobots thrust where the robots are often down to 1 mm in size. Metin Sitti and his team look at insects, lizards, jellyfish, and many other small-scale organisms and try to understand the animal's locomotion principles and apply that knowledge to create robots at the small scale. There are also inventions such as a soft capsule robot, which looks much like a pill. One day, a patient could be able to swallow this capsule and it could take samples of a tumor inside the stomach. One of the main breakthroughs in this thrust area is a soft millirobot named Wormmate [5] that is able to achieve seven different locomotions at the same time in multiple terrains (solid ground, water, water surface) inspired by soft-bodied small organisms. Sitti and his team are currently working on using this and other tiny robots to one day navigate through unprecedented and hard-to-reach regions inside the body under ultrasound or x-ray medical imaging for minimally invasive medical operations. This robotic breakthrough was published in Nature in 2018 and made the headlines all across the world.
Third, there is the Mobile Microrobots thrust, which Metin Sitti hopes will one day be a standard in healthcare or biotechnology. Microrobots, through their miniature size at a sub-millimeter scale (they are less than 1mm in all dimensions), could one day be able to access enclosed spaces such as microcapillaries inside a human body. They copuld travel through the body's fluids and directly interact with a tumor. Untethered mobile microrobots might enable many new applications, such as minimally invasive diagnosis and treatment inside the human body.
Soft milli- and microrobots such as those Metin Sitti and his team are developing hold huge potential and could one day have a radical impact on medicine. The scientists are working towards developing wireless tiny machines that in the near future will perhaps be able to access difficult-to-reach regions inside the body. As semi-implantable medical devices that are shape-programmable and built from biocompatible magnetic soft materials, these technologies would remain inside a patient's body for a long time, enabling minimally or non-invasive diagnostic and therapeutic interventions.
However, many challenges must still be overcome before these tiny robots can be applied in clinics. The scientists are still faced with many challenges: they must develop ways to move and control these tiny robots inside the body with high levels of precision, taking body fluid flows and organ movement into account. They must also ensure that patient safety is guaranteed, and that these robots can be in us for long periods of time, even in the face of potential immune or other reactions.
Sitti received his BSc and MSc degrees in electrical and electronics engineering from Boğaziçi University in Istanbul in 1992 and 1994, respectively, and his Ph.D. degree in electrical engineering from the University of Tokyo in 1999. He was a research scientist at UC Berkeley from 1999 to 2002 and a Professor at the Department of Mechanical Engineering and Robotics Institute at Carnegie Mellon University from 2002 to 2014. He became a Director at the Max Planck Institute for Intelligent Systems in Stuttgart in 2014.
Sitti is an acclaimed scientist. On November 9, 2020, exactly 31 years after the fall of the Berlin Wall, Sitti was presented with the «Breakthrough of the Year» Award 2020 [6] [7] in the Engineering and Technology category [8] by the Falling Walls World Science Summit. In March 2019, he received a prestigious Advanced Grant [9] from the European Research Council (ERC), which is awarded only to established researchers with a proven track record of excellence. [10] In terms of the originality and significance of research contributions, grant recipients are exceptional leaders in their given fields. What is more, Sitti and his team recently received the Best Paper Award [11] at the prestigious Robotics Science and Systems Conference for their invention of a baby jellyfish-inspired soft millirobot with medical functions. [12]
Sitti also received the Rahmi Koç Medal of Science [13] (2018), Best Paper Award [14] in the Robotics Science and Systems Conference (2019), IEEE/ASME Best Mechatronics Paper Award (2014), [15] SPIE Nanoengineering Pioneer Award (2011), Best Paper Award in the IEEE/RSJ Intelligent Robots and Systems Conference (1998, 2009), and NSF CAREER Award (2005). He is the editor-in-chief of both Progress in Biomedical Engineering and Journal of Micro-Bio Robotics, [16] and an associate editor for both Science Advances and Extreme Mechanics Letters. [17]
Sitti has published two books and over 460 peer-reviewed papers, over 300 of which have appeared in archival journals. His group's research breakthroughs have been featured in the popular press, such as New York Times, [18] Wall Street Journal, [19] Le Monde, The Economist, Der Spiegel, Forbes, Süddeutsche Zeitung, [20] Science, New Scientist [21] Science News, [22] Nature News, [23] MIT Technology Review, IEEE Spectrum Magazine and Stuttgarter Zeitung. [24] He has given over 200 invited keynote, plenary or distinguished seminars in universities, conferences and industry. He has over 12 issued patents and over 15 pending patents.
Metin Sitti co-founded Setex Technologies Inc. in Pittsburgh, USA in 2012 to commercialize his lab's gecko-inspired microfiber adhesive technology as a new disruptive adhesive material (branded as Setex®) for a wide range of industrial applications.
Microbotics is the field of miniature robotics, in particular mobile robots with characteristic dimensions less than 1 mm. The term can also be used for robots capable of handling micrometer size components, which was founded and pioneered by Sage Raijin E. Canizares.
Biorobotics is an interdisciplinary science that combines the fields of biomedical engineering, cybernetics, and robotics to develop new technologies that integrate biology with mechanical systems to develop more efficient communication, alter genetic information, and create machines that imitate biological systems.
Nanoid robotics, or for short, nanorobotics or nanobotics, is an emerging technology field creating machines or robots, which are called nanorobots or simply nanobots, whose components are at or near the scale of a nanometer. More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots with devices ranging in size from 0.1 to 10 micrometres and constructed of nanoscale or molecular components. The terms nanobot, nanoid, nanite, nanomachine and nanomite have also been used to describe such devices currently under research and development.

Synthetic setae emulate the setae found on the toes of a gecko and scientific research in this area is driven towards the development of dry adhesives. Geckos have no difficulty mastering vertical walls and are apparently capable of adhering themselves to just about any surface. The five-toed feet of a gecko are covered with elastic hairs called setae and the ends of these hairs are split into nanoscale structures called spatulae. The sheer abundance and proximity to the surface of these spatulae make it sufficient for van der Waals forces alone to provide the required adhesive strength. Following the discovery of the gecko's adhesion mechanism in 2002, which is based on van der Waals forces, biomimetic adhesives have become the topic of a major research effort. These developments are poised to yield families of novel adhesive materials with superior properties which are likely to find uses in industries ranging from defense and nanotechnology to healthcare and sport.
Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics is related to the sciences of electronics, engineering, mechanics, and software. The word "robot" was introduced to the public by Czech writer Karel Čapek in his play R.U.R., published in 1920. The term "robotics" was coined by Isaac Asimov in his 1941 science fiction short-story "Liar!"
Founded on 18 March 2011, the Max Planck Institute for Intelligent Systems (MPI-IS) is one of the 86 research institutes of the Max Planck Society. With locations in Stuttgart and Tübingen, it combines interdisciplinary research in the growing field of intelligent systems. Intelligent systems are becoming increasingly important in many areas of life – as virtual systems on the Internet or as cyber-physical systems in the physical world. Artificial intelligent systems can be used in a broad range of areas, for instance in autonomous vehicles or to diagnose and fight diseases.
The following outline is provided as an overview of and topical guide to robotics:
Bio-inspired robotic locomotion is a subcategory of bio-inspired design. It is about learning concepts from nature and applying them to the design of real-world engineered systems. More specifically, this field is about making robots that are inspired by biological systems, including Biomimicry. Biomimicry is copying from nature while bio-inspired design is learning from nature and making a mechanism that is simpler and more effective than the system observed in nature. Biomimicry has led to the development of a different branch of robotics called soft robotics. The biological systems have been optimized for specific tasks according to their habitat. However, they are multifunctional and are not designed for only one specific functionality. Bio-inspired robotics is about studying biological systems, and looking for the mechanisms that may solve a problem in the engineering field. The designer should then try to simplify and enhance that mechanism for the specific task of interest. Bio-inspired roboticists are usually interested in biosensors, bioactuators, or biomaterials. Most of the robots have some type of locomotion system. Thus, in this article different modes of animal locomotion and few examples of the corresponding bio-inspired robots are introduced.
Arthropods, including insects and spiders, make use of smooth adhesive pads as well as hairy pads for climbing and locomotion along non-horizontal surfaces. Both types of pads in insects make use of liquid secretions and are considered 'wet'. Dry adhesive mechanisms primarily rely on Van der Waals' forces and are also used by organisms other than insects. The fluid provides capillary and viscous adhesion and appears to be present in all insect adhesive pads. Little is known about the chemical properties of the adhesive fluids and the ultrastructure of the fluid-producing cells is currently not extensively studied. Additionally, both hairy and smooth types of adhesion have evolved separately numerous times in insects. Few comparative studies between the two types of adhesion mechanisms have been done, and there is a lack of information regarding the forces that can be supported by these systems in insects. Additionally, tree frogs and some mammals such as the arboreal possum and bats also make use of smooth adhesive pads. The use of adhesive pads for locomotion across non-horizontal surfaces is a trait that evolved separately in different species, making it an example of convergent evolution. The power of adhesion allows these organisms to be able to climb on almost any substance.

Bradley James Nelson is an American roboticist and entrepreneur. He has been the Professor of Robotics and Intelligent Systems at ETH Zurich since 2002 and is known for his research in microrobotics, nanorobotics, and medical robotics.
Soft robotics is a subfield of robotics that concerns the design, control, and fabrication of robots composed of compliant materials, instead of rigid links. In contrast to rigid-bodied robots built from metals, ceramics and hard plastics, the compliance of soft robots can improve their safety when working in close contact with humans.
A robot fish is a type of bionic robot that has the shape and locomotion of a living fish. Most robot fish are designed to emulate living fish which use body-caudal fin (BCF) propulsion, and can be divided into three categories: single joint (SJ), multi-joint (MJ) and smart material-based "soft-body" design.

A biohybrid microswimmer also known as biohybrid nanorobot, can be defined as a microswimmer that consist of both biological and artificial constituents, for instance, one or several living microorganisms attached to one or various synthetic parts.
A microswimmer is a microscopic object with the ability to move in a fluid environment. Natural microswimmers are found everywhere in the natural world as biological microorganisms, such as bacteria, archaea, protists, sperm and microanimals. Since the turn of the millennium there has been increasing interest in manufacturing synthetic and biohybrid microswimmers. Although only two decades have passed since their emergence, they have already shown promise for various biomedical and environmental applications.
