This paper presents a method that can acquire fuzzy rules for Sony legged robot behaviours automatically. We use fuzzy logic controllers (FLCs) to design robot behaviours. The antecedents of the FLCs are pre-design, while their consequences are left for automatic acquisition. Once the consequences are optimally chosen, the robot behaviours are well designed. Genetic algorithms (GAs) are employe...

This paper discusses the general concept of the Super Mechano-System, or SMS and its anticipated applications. The SMS is a new type of robot system, which can transform its shape and also its internal control system in accordance with the given tasks. Snake robots, running and walking robot with manipulation function, group robots, and unified and reconfigurable robots are the three main examp...

In this paper, the roll and pitch dynamics of a biologically inspired quadruped water runner robot are analyzed, and a stable robot design is proposed and tested. The robot’s foot–water interaction force is derived using drag equations. Roll direction instability is attributed to a small roll moment of inertia and large instantaneous roll moments generated by the foot–water interaction forces. ...

This paper describes how a distributed neural architecture for the general control of robots has been applied for the generation of a walking behaviour in the Aibo robotic dog. The architecture described has been already demonstrated useful for the generation of more simple behaviours like standing or standing up. This paper describes specifically how it has been applied to the generation of a ...

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...

Visually-guided locomotion is important for autonomous robotics. However, there are several difficulties, for instance, the head shaking that results from the robot locomotion itself that constraints stable image acquisition and the possibility to rely on that information to act accordingly. In this article, we propose a controller architecture that is able to generate locomotion for a quadrupe...

Robots that have been optimized in simulation often underperform the real world comparison to their simulated counterparts. This difference performance is called a reality-gap. In this paper, we use two methods, genetic algorithm and topology optimization, optimize quadruped robot. We look at original robots’ reality compare results. Both methods show improvement robot’s efficiency, however opt...

The behavior of a robot is emerged from the interaction between body, control, and environmental dynamics. The research group B–3 aims to design body and control dynamics for emerging adaptive locomotion. We investigate three types of locomotion, biped, quadruped, and snake-like and developed robots. We also discuss on the lower control architecture for realizing reactive adaptive locomotion.
