A pelican is a large water bird with a distinctive pouch under the beak, belonging to the bird family Pelecanidae.Modern pelicans, of which there are eight species, are found on all continents except Antarctica. This system of „Pelican Robot? is designed in such a way that it can perform task of moving on land, water & underwater. This robot will perform all basic operations i.e. forward, backward, left and right movements on land as well as under water. It will also float on water. As it works wirelessly we can control robot anywhere within the mobile range. It can be used in war conditions to monitor the actual condition there on cameras where there is danger for human beings. Importantly by using less hardware we can use this technology at low cost. The first part of this paper includes introduction of the complete system designed. Second part covers the design aspects of Pelican Robot system such as block diagram and its description. Different mechanisms used here are Sinking mechanism for under water applications, Deo mechanism for uplifting the robot on the surface of water from underwater. Furthermore Floating mechanism is used to drive the robot on the water surface. This mechanism has been covered in third part of the paper. Remaining paper covers the controlling aspects of the robot and the system specifications. Experimental results show that the system worked successfully on the land, on the surface of water as well as underwater and thus can be used for researches in marine life, remote and hazardous land areas and many other fields.
