Water Robotics

Water Robots, are basically a floating robot for various uses and needs. These robots can work and perform over or under water surfaces. The application in which these are used are cleaning water by collecting objects floating over water. participants of workshop will be taught to design and develop a robot which can float as well as can collect objects floating unanimously over water surfaces. These robots will be controlled by wired remote control from ground surfaces.


Can access computer system and make use of internet to perform search over Google.
