چکیده

Gait generation is the formulation and selection of a sequence of coordinated leg and body motions that propel a legged robot along a desired path. Approaches to gait generation can be classified into control, behavioral, rule-based, and constraintbased paradigms. We survey these models of gait generation and introduce the Ambler, a hexapod robot that can circulate its legs to produce unique gaits. Then we present kinematic, collision, terrain, support, and stability constraints available for gait generation, and discuss our progress using a constraint-based method to generate the Ambler’s gait.

Energy Dissipation Rate Control Via a Semi-Analytical Pattern Generation Approach for Planar Three-Legged Galloping Robot based on the Property of Passive Dynamic Walking

In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP). As yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...

Gait Generation for a Bipedal System By Morris-Lecar Central Pattern Generator

The ability to move in complex environments is one of the most important features of humans and animals. In this work, we exploit a bio-inspired method to generate different gaits in a bipedal locomotion system. We use the 4-cell CPG model developed by Pinto [21]. This model has been established on symmetric coupling between the cells which are responsible for generating oscillatory signals. Th...

A Hybrid Evolutionary Algorithm for Gait Generation of Sony Legged Robots

This paper presents a hybrid evolutionary algorithm (EA) for developing locomotion gait of Sony legged robots. The selection of EA parameters such as the population size and recombination methods is made to be flexible and strive towards optimal performance autonomously. An interactive software environment with an overhead CCD camera is used to evaluate the performance of the generated gaits. T...
