Santhakumar abstract:The paper discusses the development of a linkage based amphibian legged robot for exploration and surveillance tasks. The proposed system can walk on both ground and water surfaces. The proposed system has two major mechanisms for its motion namely a planar eight bar Jansen mechanism as a leg and an Ackermann steering …
authors: Somak Sengupta, Pramod Bhatia abstract: The natural and the manmade terrains on planet Earth vary from place to place. The availability of affordable and safe modes of transportation on the different types of terrain is currently costly and limited. This problem is mainly due to the limitations of wheels which fail to deliver on …
