You could make a robot that does any one of those three very well, but being able to do all three, and many other difficult combinations, is what makes snake robots exceptional. Additionally, many snake robots are constructed by chaining together a number of independent links. Similarly, snakebots can move by adapting their shape to different periodic functions. Software for snakebots are also being developed by NASA for them to be able to learn by experience the skills to scale obstacles and remember the techniques. For example, sidewinding and lateral undulation are both gaits.
The application of parallel mechanism in snake robot can provide considerable dexterity and support-ability to overcome the aforementioned drawback. When researchers refer to how a snakebot moves they often refer to a specific gait, where a gait is just a periodic mode of locomotion. December 13, 2008 Researchers at the Robotics and Mechanisms Laboratory at Virginia Tech have designed a series of serpentine robots that are able to climb poles and inspect structures too dangerous or inaccessible for humans. Available also for demonstrations and exhibitions, please contact us for more details and pricing. Also, snakebots can be used by animal control officers to subdue rabid or invasive creatures.
This paper presents a bionic parallel module for snake robot inspired by the anatomy of biological snake. To generate four distinct gaits of living snake, three motion screws of the mechanism are obtained via mobility analysis. Currently the robots are tethered to laptops, but future designs will incorporate a microprocessor and power source, allowing them to operate independently. Thus snakebots are currently being developed to assist search and rescue teams. A Gen 2 snakerobot from NASA demonstrating rearing capabilities A snakebot, also known as snake robot, is a biomorphic hyper-redundant robot that resembles a biological snake. However, earlier snake robot designs are inadequate to imitate the living snake locomotion comprehensively, since the deficiency of mobility in each single module. The HyDRAS models (Hyper-redundant Discrete Robotic Articulated Serpentine for climbing) use electric motors, while the CIRCA (Climbing Inspection Robot with Compressed Air) uses a compressed air muscle.
