A group of scientists has predicted that moon village will be reality by 2030. By the cooperation of astronauts and robotic systems on the moon it will be reality by 2040. Scientists raised this statement during the symposium conducted by European Space Agency (ESA) in Netherlands titled as "Moon 2020-2030, A New Era of Coordinated Human and Robotic Exploration".
Four bar linkage are the closed loop kinematic linkage , they perform a wide variety of motions with a few simple parts. This project discusses the design & fabrication of one such mechanism (Four Bar Mechanism). In this project Six Leg Kinematic movement works on Grashof’s principle which states that the sum of the length of the shortest and longest links must be less than or equal to the some of the other two links. However this condition is necessary but nor sufficient. Mechanism satisfying this condition will fall into crank-rocker mechanism, double crank mechanism and double rocker mechanism. A frame, connecting rod, crank & a lever constitute to obtain the required motion. In this project we tried to show mainly the application of simple four bar mechanism. PHOTOS & DRAWINGS APPLICATIONS It would be difficult to compete with the efficiency of a wheel on smooth hard surfaces but as condition increases rolling friction, this li...
