چکیده

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 quadruped robot gaits. In addition, an optimization procedure using either MathWorks fmincon or a Differential Evolutionary (DE) algorithm is employed to determine the optimum motion and robot physical parameters related to energy efficiency. Using “multiple gait graphs”, the effects of leg compliance, gravity and ground inclination are determined.

Autonomous Evolution of Gaits with the Sony Quadruped Robot

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 previou...

The effect of motor action and different sensory modalities on terrain classification in a quadruped robot running with multiple gaits

Discriminating or classifying different terrains is an important ability for every autonomousmobile robot. A variety of sensors, preprocessing techniques, and algorithms in different robots were applied. However, little attentionwas paid to theway sensory datawas generated and to the contribution of different sensory modalities. In this work, a quadruped robot traversing different grounds using...

Learning Fast Quadruped Robot Gaits with the RL PoWER Spline Parameterization

Legged robots are uniquely privileged over their wheeled counterparts in their potential to access rugged terrain. However, designing walking gaits by hand for legged robots is a difficult and time-consuming process, so we seek algorithms for learning such gaits to automatically using real world experimentation. Numerous previous studies have examined a variety of algorithms for learning gaits,...

Towards Optimal Hybrid Control Solutions for Gait Patterns of a Quadruped

We consider the problem of finding optimal gaits for a quadruped robot. Paths are sought which minimize the actuation energy required for walking in an attempt to approximate natural motion. The number of possible gaits for a quadruped is quite large when one considers varied orders of leg motion, different liftoff times, and various ground contact combinations for the legs. The problem is trea...
