چکیده

Changes in pedality can occur in animals due to injury, congenital defects, or behaviour. Here, an attempt is made to reproduce similar conditions on a nominally quadrupedal robot upon losing functionality in one leg, rendering it tripedal. The change in walking speed and energy efficiency are examined for both quadrupedal amble and basic tripedal walking gaits.

On Passive Quadrupedal Bounding with Flexible Linear Torso

This paper studies the effect of flexible linear torso on the dynamics of passive quadruped bounding. A reduced-order passive and conservative model with linear flexible torso and springy legs is introduced. The model features extensive spine deformation during high-speed bounding, resembling those observed in a cheetah. Fixed points corresponding to cyclic bounding motions are found and calcul...

Analysis of gaits for a rotating tripedal robot

A goal of robotics has been to develop mechanisms that have the efficiency and speed of wheeled robots with the terrain flexibility of legged robots. In previous work, we have proposed a unique three-legged mechanism, the rotopod, designed to integrate these two useful approaches to locomotion. In this paper, we present an analysis of the variety of gaits that can be exhibited by the rotopod. W...

Stable Gait Planning and Robustness Analysis of a Biped Robot with One Degree of Underactuation

In this paper, stability analysis of walking gaits and robustness analysis are developed for a five-link and four-actuator biped robot. Stability conditions are derived by studying unactuated dynamics and using the Poincaré map associated with periodic walking gaits. A stable gait is designed by an optimization process satisfying physical constraints and stability conditions. Also, considering...

Gait Development On A Direct Drive, Quadrupedal Robot

The development of dynamic, quadrupedal robots is becoming an increasing topic of interest with the growing demand for robotic interaction in the human environment, but they require adaptable control schemes to address the challenges encountered while traversing real world terrains. In this study, we explore improvements to both physical and control methods to a quadrupedal system in order to a...
