چکیده

We propose a locomotion technique for a legged robot that is high-centered, i.e., a robot stuck on a block with its legs dangling in air. By using its legs as reaction masses, the robot might be able to rock and roll on its stomach and incrementally move forward off the block, a form of legless locomotion using halteres. With locomotion of high-centered robots using body attitude oscillations as motivation, this paper focuses on studying the interplay between leg motions and body roll-pitch-yaw dynamics. We present results from simulation of two simplified models in which body motion is restricted to the roll and roll-yaw space respectively.

Legless Locomotion: A Novel Locomotion Technique for Legged Robots

We present a novel locomotion strategy called legless locomotion that allows a round-bodied legged robot to locomote approximately when it is high-centered. Typically, a high-centered robot is stuck since the robot’s legs do not touch the ground. Legless locomotion uses the legs as a reaction mass to set up oscillatory body rotations which when coupled with ground contact gradually translate th...

Legless Locomotion: Concept and Analysis

This thesis presents a novel locomotion technique, called legless locomotion, for convex-bodied legged robots. The motivation for studying legless locomotion stems from the mobile robot recovery problem, stated simply as what should a robot do when trapped? Legless locomotion is the technique of locomotion for a legged robot which has no leg-ground contact, but can use the swinging legs to exci...

An Approximate Decoupled Dynamics and Kinematics Analysis of Legless Locomotion

We present a novel analysis technique to understand the dynamics of a recently described locomotion mode called legless locomotion. Legless locomotion is a locomotion mode available to a legged robot when it becomes high-centered, that is, when its legs do not touch the ground. Under these conditions, the robot may still locomote in the plane by swinging its legs in the air, rocking on its body...

Convergent evolution and locomotion through complex terrain by insects, vertebrates and robots.

Arthropods are the most successful members of the animal kingdom largely because of their ability to move efficiently through a range of environments. Their agility has not been lost on engineers seeking to design agile legged robots. However, one cannot simply copy mechanical and neural control systems from insects into robotic designs. Rather one has to select the properties that are critical...

Semi-Passive Dynamic Walking Approach for Bipedal Humanoid Robot Based on Dynamic Simulation

The research on the principles of legged locomotion is an interdisciplinary endeavor. Such principles are coming together from research in biomechanics, neuroscience, control theory, mechanical design, and artificial intelligence. Such research can help us understand human and animal locomotion in implementing useful legged vehicles. There are three main reasons for exploring the legged locomot...
