چکیده

A trend in robotics is towards legged robots. One of the issues with legged robots is the development of gaits. Typically gaits are developed manually. In this paper we report our results of autonomous evolution of dynamic gaits for the Sony Quadruped Robot. Fitness is determined using the robot's digital camera and infrared sensors. Using this system we evolve faster dynamic gaits than previously manually developed.

Ga-based Gait Generation of Sony Quadruped Robots

This paper presents a GA (Genetic Algorithm) approach to the development of locomotion gait for Sony quadruped robots. The selection of GA 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 ...

Autonomous Learning of Stable Quadruped Locomotion

A fast gait is an essential component of any successful team in the RoboCup 4-legged league. However, quickly moving quadruped robots, including those with learned gaits, often move in such a way so as to cause unsteady camera motions which degrade the robot’s visual capabilities. This paper presents an implementation of the policy gradient machine learning algorithm that searches for a paramet...

Gait transition and modulation in a quadruped robot: A brainstem-like modulation approach

In this article, we propose a bio-inspired architecture for a quadruped robot that is able to initiate/stop locomotion; generate different gaits, and to easily select and switch between the different gaits according to the speed and/or the behavioral context. This improves the robot stability and smoothness while locomoting. We apply nonlinear oscillators to model Central Pattern Generators (CP...

Quadruped Optimum Gaits Analysis for Planetary Exploration

Leg compliance, gravity and ground have a significant impact on the performance and gait characteristics of a quadruped robot. This paper presents results obtained using a planar lumped parameter model of a quadruped robot and an extensive research scheme to determine optimum design parameters for a quadruped moving in different gravity environments. Hildebrand diagrams are used to classify qua...

Evolution of locomotion in a simulated quadruped robot and transferral to reality

In this paper, we study the suitability of using simulation in the evolution of locomotion in a quadruped robot. The goal of the evolution is to design a control system that produces fast gaits. We evolve gaits in simulation, and then the best controllers are transferred into the real custom built robot and compared with their simulated versions. The results show effective locomotion, with a 1....
