Abstract: A class of robots specifically adapted to climb periodic lattices. These “relative robots” are designed for a specific lattice structure and use the regularity of the structure to simplify path planning, align with minimal feedback, and reduce the number of degrees of freedom (DOF) required to locomote. These robots can perform vital inspection and repair tasks within the structure that larger truss construction robots cannot perform without modifying the structure. A particular embodiment is a robot designed to traverse a cubooctahedral (CubOct) cellular solids lattice using only two motions: climbing and turning.

Abstract: A robotic platform for traversing and manipulating a modular 3D lattice structure is described. The robot is designed specifically for its tasks within a structured environment, and is simplified in terms of its numbers of degrees of freedom (DOF). This allows for simpler controls and a reduction of mass and cost. Designing the robot relative to the environment in which it operates results in a specific type of robot called a “relative robot”. Depending on the task and environment, there can be a number of relative robots. This invention describes a bipedal robot which can locomote across a periodic lattice structure made of building block parts. The robot is able to handle, manipulate, and transport these blocks when there is more than one robot. Based on a general inchworm design, the robot has added functionality while retaining minimal complexity, and can perform numerous maneuvers for increased speed, reach, and placement.

Abstract: A shape-morphing ultralight structure using materials that dramatically increase the efficiency of load-bearing aerostructures that includes a programmable material system applied as a large-scale, ultralight, and conformable (shape-morphing) aeroelastic structure. The use of a modular, lattice-based, ultralight material results in stiffness and density typical of an elastomer. This, combined with a building block-based manufacturing and configuration strategy, enables the rapid realization of new adaptive structures and mechanisms. The heterogeneous design with programmable anisotropy allows for enhanced elastic and global shape deformation in response to external loading, making it useful for tuned fluid-structure interaction. The present invention demonstrates an example application experiment using two building block types for the primary structure of a 4.27 m wingspan aircraft with spatially programed elastic shape morphing to increase aerodynamic efficiency.
