A REVIEW OF AMPHIBIOUS ROBOTS

People in today's society embrace robot involvement as a smarter tool. The mid-twentieth century was a pivotal period in robotic research and development. Robots evolved from there as an industrial assistance device to the present amphibious robots. The human function is altering as a result of robotics. Robots are gradually infiltrating every industry, including manufacturing, healthcare, delivery, education, and space exploration. Scientists and researchers working in robotics place equal emphasis o n ultra-large and microrobots. The notable trend in the sector is autonomous mobile robots, which automate the majority of human labor without actual human interaction. However, amphibious robots are a new developing technology in robotics that might revolutionize space functionality. This paper consists of the current classifications of amphibious robots, which primarily i nclude the legged amphibious bot, duck feet inspired amphibious robot, salamander-like amphibious robot, sheds light on swimming and crawling in a snake-like amphibious robot which are optimized online, and it outlines a simulation-based design optimization strategy for an amphibious transformable robot carried out in different software like ANSYS FLUENT.
