Since its inception in 1950, the field of modern robotics has come a long way. The industry has grown to range from large, heavy-duty machinery to very precise and delicate robots. During this rapid evolution, we have seen the rise of soft robotics, which are key to finally exploring the boundaries of what robots are capable of.
The term “soft robot” describes a robot that is flexible and compliant, as opposed to the more familiar hard and rigid systems. They’re usually made of elastic and deformable materials such as silicone, rubber, or gels, and function through pneumatic systems, or automation through the use of compressed air. The significance of this boils down to a very simple question: What can humans do that robots can’t? There are a lot of activities, especially very precise and adaptable activities since humans have the advantage of dexterous fingers and flexible muscles. The field of soft robotics fills these gaps in ability by providing us with a robotic system that is capable of almost anything.
Some projected uses of this field are heavily considered for human habitation of the Moon or even of Mars. The value of systems that are nearly biological in ability but have no need for water or food is indisputable. They can also navigate through tight spaces and handle fragile objects and could therefore prove significant to search and rescue needs as well. With their increasing similarity to muscles and tendons, the field of soft robotics is also looking at a possible breakthrough in prosthetics, disability assistance, and even physical therapy.
Despite all of this, soft robotics remain relatively unknown. Their existence and capabilities are expanding rapidly, especially in well-known labs like at Langley, but yet students in the engineering field remain unawares. Help spread the word about this amazing field, get more bright students involved, and maybe, one day soon, the field can expand to encompass all of its massive potential, possibly changing lives along the way.
Here is a video from Langley Soft Robots featuring this unique technology:
