About this Research Topic
Soft robots usually imitate creatures in nature whose bodies are made of soft materials that can easily realize biomimetic motions such as creeping, crawling, twisting, rolling, and swimming, etc. Due to their similar continuous deformation capacity and a high degree of freedom with bio-inspired muscles and tissues, soft robots can change their shape and size actively or passively to adapt to the environment, protect themselves from damage when bearing huge impact loads, or even squeeze through openings smaller than their nominal dimensions. Therefore, soft robotics has great potential for application in the unstructured environment and has become an international cutting-edge research hotspot in the field of robotics.
The large deformation and energy absorption characteristics of soft bodies can allow soft robots to have good flexibility, safety, and environmental adaptability, but also reduces the inertial effects, thus limiting their moving speed and efficiency. Particularly with respect to the robotic applications in measurement, detection, and search and rescue, the robot’s locomotion characteristics and maneuverability are of crucial importance. However, while many soft locomotion robots inspired by soft-bodied animals (such as caterpillars, inchworms, earthworms, starfish and octopuses, etc.) have been developed, their locomotion performances are still unsatisfactory. Most of them remain tethered and their movement speed, reliability, adaptability, and autonomy are still weak. To realize locomotion performance comparable with bionic objects or their rigid counterparts and meet the demand of handling unexpected interactions with unstructured and unpredictable environments, soft locomotion robots are being faced with many opportunities and challenges.
