A snake-like robot can move in not only the dry ground but also various viscous environments of water, mud, and clay by exhibiting undulating motions. To construct numerical model including fluid–structure interaction for under above-mentioned environments, added mass drag coefficients must be identified via experimentation because they depend on shape body, roughness skin, viscosity fluid. In ...

Mobile robotics have long been considered a possible tool for everything from remote diagnostics to search and rescue. Snake-like robots in particular have shown significant promise in search and rescue operations due to their ability to traverse a very wide range of sizes and shapes. Such robots can crawl in spaces not much larger than the robot itself, as well as climb over obstacles nearly a...

This letter presents a gripper module for snake-like robot to perform search and rescue tasks in narrow space. The proposed has three features: (1) It can accommodate the fingers inside its body. (2) that grip objects with irregular surfaces stably. (3) One of is equipped camera on fingertip To implement above features small, light, compact module, we propose novel design eight degrees freedom....

Body undulation used by snakes and the physical architecture of a snake body may offer significant benefits over typical legged or wheeled locomotion designs in certain types of scenarios. A large number of research groups have developed snake-inspired robots to exploit these benefits. The purpose of this review is to report different types of snake-inspired robot designs and categorize them ba...

With a compliant structure and excellent bending properties, continuum robot has hyper-redundant degrees of freedom, and can be used in space-constrained environments as the aircraft fuel tank. Therefore, a continuum robot is designed to help crews inspect aircraft fuel tanks, which can improve maintenance efficiency and reduce the intensity of crews. According to the requirements of aircraft f...
