Self-organized adaptive legged locomotion in a compliant quadruped robot

Self-organized adaptive legged locomotion in a compliant quadruped robot

In this contribution we present experiments of an adaptive locomotion controller on a compliant quadruped robot. The adaptive controller consists of adaptive frequency oscillators in different configurations and produces dynamic gaits such as bounding and jumping. We show two main results: (1) The adaptive controller is able to track the resonant frequency of the robot which is a function of di...

Learning Compliant Locomotion on a Quadruped Robot

Over the last decades, compliant locomotion and manipulation have become a very active field of research, due to the versatility that robots with such capabilities would offer in many applications. With very few exceptions, generally, robotic applications and experiments take place in controlled environments. One of the reasons of this limited use is that in real world scenarios, robots need to...

Adaptive Locomotion Controller for a Quadruped Robot

Dynamic Modeling and Simulation of Compliant Legged Quadruped Robot

Quadruped robot has many advantages over wheeled mobile robots, but it is a discrete system in which joints of each leg has to operate in particular fashion to get the desired locomotion. So, dynamics plays an important role in the operation and control of quadruped robot. Proper conception of the dynamic formulation is must for the complex system like quadruped robot. Here, an attempt is made ...

Adaptive gait pattern control of a quadruped locomotion robot

The authors have proposed a control system of a quadruped locomotion robot by using nonlinear oscillators. It is composed of a leg motion controller and a gait pattern controller. The leg motion controller drives the actuators of the legs by using local feedback control. The gait pattern controller involves nonlinear oscillators with mutual interactions. In this paper, capability of adaptation ...
