This review paper provides the latest researches in the various fields of robotics to make daily routine work more comfortable, convenient, efficient, and economical. This paper deals with different category of robots like climbing robots, eyelid closure robots, facial wearable robots, flying UAV, swarm robots, and fish bio robotics. Eyelid closure robots will be very much helpful for facial paralyzed patients. Robots working with camouflage properties with high resolution of pattern, area of the pattern, and robustness against the failure of an individual is presented in this paper. Fish bio-robotics in the field of biomechanics play an essential role in the field of the hydrodynamics of self-propulsion. Information on different functionality of robots with different parts and components working efficiently is presented here.

Keywords : Wall Climbing Robots, Flying UAV, Bio Robotics, Swarm Robots.
