Analysis on Effective Walking Pattern for Multi-Legged Robots

Analysis of Six-legged Walking Robots

In the present paper, an attempt has been made to carry out kinematic and dynamic analysis of a six-legged robot. A three-revolute (3R) kinematic chain has been chosen for each leg mechanism in order to mimic the leg structure of an insect. Denavit–Hartenberg (D-H) conventions are used to perform kinematic analysis of the six-legged robot. The direct and inverse kinematic analysis for each leg ...

Generating walking behaviours in legged robots

Many legged robots have been built with a variety of different abilities, from running to hopping to climbing stairs. Despite this however, there has been no consistency of approach to the problem of getting them to walk. Approaches have included breaking down the walking step into discrete parts and then controlling them separately, using springs and linkages to achieve a passive walking cycle...

Force Sensing for Multi-legged Walking Robots: Theory and Experiments – Part 2: Force Control of Legged Vehicles

1.1 Main approaches and principles of force control Approaches to manipulator control using force information can be subdivided into two major groups. The first group uses logic branching of the control when the measured force satisfies certain conditions. The second group introduces continuous force feedback as an explicit force control or active force feedback method. The basic approaches to ...

Virtual Reality to Simulate Adaptive Walking in Unstructured Terrains for Multi-Legged Robots

Force Sensing for Multi-legged Walking Robots: Theory and Experiments – Part 1: Overview and Force Sensing

This paper is intended to direct the attention of researchers and designers of multi-legged walking robots to the problem of force sensing for such vehicles. The use of force information enables such systems to achieve new mechanical properties, increases the reliability and functional capabilities of walking robots and simplifies many control algorithms. Interest in developing walking machines...
