Abstract
A multidirectional locomotive module with omnidirectional bending that is compliant along multiple axis is provided. The locomotive module includes, (A) a first part that includes (i) one or more circular rigid components which are coupled using a two degree of freedom joint, (ii) bending actuator that actuates the two degree of freedom joint enabling bending of the multidirectional locomotive module to an angle ranging from 0 to 90 degrees about a Z-axis in a direction to achieve surface compliance with an external surface, and (B) a second part that is elongated in shape with circular cross-section along a surface length and hemispherical in shape an end portion with a surface that is formed by a power transmission sprocket chain and an arrangement of curved components enabling sideways rolling of the multidirectional locomotive module, also enabling wheeled and legged locomotion in vertical position.
