Abstract – In this paper, discuss the spider mechanism (Klan’s The scientific study of legged locomotion began just very a mechanism) for any random movements, whenever the century ago when Leland Stanford, then governor of transformation by wheel is not possible. In these aspects, the California, commissioned Edward Muybridge to find out proposed assembled spider mechanism (Klan’s mechanism) for whether or not a trotting horse left the ground with all four any random movements in hectic places. It can step over curbs, feet at the same time [11]. The Stanford had wagered that it climb stairs or travel areas that are currently not accessible with wheels.

The remaining rotation of the crank allows the foot to be raised to a predetermined height before returning to the starting position and repeating the cycle. Two of these linkages coupled together at the crank and one-half cycle out of phase with each other will allow the frame of a vehicle to travel parallel to the ground [7], [8]. The Klann linkage provides many of the benefits of more advanced walking vehicles without some of their limitations. It can step over curbs, climb stairs, or travel into areas that are currently not accessible with wheels but do not require microprocessor control or multitudes of actuator mechanisms.

Dr. K.Ankamma, Professor, Department of Mechanical Engg., MGIT, Gandipet, Hyderabad-75,email: [email protected] ABSTRACT: Underground mining is best with numerous problems such as ground movement (fall of roof/sides), inundation, air blast, etc.; apart from gas explosions and dust explosions that are restricted to coal mines. Whatever may be the cause and type of accident or the extent of damage caused, it is a horrendous task for the rescue team to reach the trapped miners. The accident/irrespirable zone contains increased levels of harmful gases like carbon dioxide and carbon monoxide and explosive gases like methane apart from a deficiency of Oxygen. The entire gallery or roadway is filled with dust and smoke, or water in case of inundation, hindering the visibility of rescue personnel. Thus, it is not an ideal situation for the rescue team to perform the operations. The first few hours after the disaster are the critical moments that could be the difference between life and death of the trapped miners. Hence, the ideal solution in such cases would be to deploy a wireless 6-legged robot equipped with various gas sensors, ultrasonic sensors, PIR sensor and vision system to aid visibility even in extremely low light conditions. This project reviews some notable examples from the past and highlights designing and developing a 6-legged robot meeting such requirements for mine rescue robots along with some limitations encountered in the design of such robots.

In a broader sense, robots have to face two common tasks during exploration, namely, walking on the drylands and swimming through the water. This research aims to design and develop an amphibious robot, which incorporates a webbed duck feet design to walk on different terrains, swim in the water, and tackle obstructions on its way. The designed robot is compact, easy to use, and also has the abilities to work autonomously. Such a mechanism is implemented by designing a novel robotic webbed foot consisting of two hinged plates. Because of the design, the webbed feet are able to open and close with the help of water pressure. Klann linkages have been used to convert rotational motion to walking and swimming for the animal’s gait. Because of its amphibian nature, the designed robot can be used for exploring tight caves, closed spaces, and moving on uneven challenging terrains such as sand, mud, or water.

Kamidi Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Masters of Science in Mechanical Engineering Pinhas Ben-Tzvi, Chair Alexander Leonessa Tomonari Furukawa December 19, 2017 Blacksburg, Virginia Keywords: Legged Locomotion , Mechanism & Design Copyright 2017, Vinaykarthik R. Kamidi Design and Integration of a Novel Robotic Leg Mechanism for Dynamic Locomotion at High-Speeds Vinaykarthik R. Kamidi ABSTRACT Existing state-of-the-art legged robots often require complex mechanisms with multi-level controllers and computationally expensive algorithms. Part of this is owed to the multiple degrees of freedom (DOFs) these intricate mechanisms possess and the other is a result of the complex nature of dynamic legged locomotion. The underlying dynamics of this class of non-linear systems must be addressed in order to develop systems that perform natural human/animal-like locomotion. However, there are no stringent rules for the number of DOFs in a system; this is merely a matter of the locomotion requirements of the system. In general, most systems designed for dynamic locomotion consist of multiple actuators per leg to address the balance and locomotion tasks simultaneously. In contrast, this research hypothesizes the decoupling of locomotion and balance by omitting the DOFs whose primary purpose is dynamic disturbance rejection to enable a far simplified mechanical design for the legged system. This thesis presents a novel single DOF mechanism that is topologically arranged to execute a trajectory conducive to dynamic locomotive gaits.

The wheels are the main components of the transportation vehicle. Without wheels the vehicle cannot move from its stationary state. But this wheel is having few drawbacks. We know wheels can catch grip on normal roads easily. But these wheels slip on wet areas, snowy region, in muddy region and also on high elevation. So to allow vehicles to move on such areas the wheels can be replaced by the insect walking gait pattern. The best effective leg mechanisms are Joe Klann’s Mechanism and Theo Jansen’s Mechanism. By using Joe Klann Mechanism the wheel gets look of spider leg. The purpose of our paper is to make the wheeled vehicle to move in muddy regions, high elevation, etc by reinstating the wheels with insect gait (with insect leg). This is useful in dangerous material handlings, detecting and clearing the explosive minefields without making any harm to human troops. Keywords: Wheels, Joe Klann Mechanism, Theo Jansen Mechanism, Explosive Minefields, Human Troop. I. INTRODUCTION Walking mechanisms are built up in such a way that they move same as the insects move.

It composes a system consisting of many small robots with simple control mechanisms capable of achieving complex collective behaviors on the swarm level such as aggregation, pattern formation, and collective transportation. The most remarkable characteristic of swarm robots are the ability to work cooperatively to achieve the common goal. Thus swarm robotics is a new approach to the coordination of multi-robot system which consist large number of simple robots which takes it inspiration from social insects. It is an interesting alternative to classical approaches to robotics because of some properties of problem solving present in the social insects, which is flexible, robust, decentralized and self-organized. This work gives overview of swarm robotics concept and its application in material handling. Computational swarm intelligence is modelled on the social behavior of animals and its principle application as an optimization technique. Swarm robotics is relatively new and rapidly developing field which draws an inspiration from swarm intelligence Keywords- Klann Mechanism, Swarm Robotics, Linkages, Sensor, Wi-Fi Bot I. INTRODUCTION Nature has always inspired researchers. Swarm robotics is a branch of multi-robot systems that embrace the ideas of biological swarms such as insect colonies, flocks of birds and schools of fish.

Abstract: During the most recent years, a lot of research has been done in creating robots with more self- governance so that they can overcome the challenges that real world environments present. The robot's limited versatility in real world applications can be overcome by the development of Legged robots. Also, as they permit movement in unavailable territory to robots with wheels, Legged Robots are more advantageous. But the potency of the legged robots explicitly its energy usage among alternate points of view really fall behind robots that use wheels.
