Reconfiguring a Chain of Cubes
نویسندگان
چکیده
Any configuration of a chain of cubes can be transformed into any other while maintaining contact between adjacent cubes in the chain using a quadratic number of moves. We show that this result is also true in the more constrained setting of a “Kibble chain” where the cubes are threaded on an elastic string, and slits in the cubes allow limited turns at joints.

Motion Planning for a Modular Self-Reconfiguring Robotic System
In this paper, we address the issue of motion planning for a bipartite class of modular self-reconfiguring robotic system (I-Cubes) that is a collection of active elements providing reconfiguration (3-DOF manipulators called links) and passive elements acting as connectors (cubes). The links, capable of attaching/detaching themselves from/to cubes, can position and orient the cubes. Current sol...
متن کاملMechatronic Design of a Modular Self-Reconfiguring Robotic System
Design and implementation of I-Cubes, a modular selfreconfigurable robotic system, is discussed. 1-Cubes is a bipartite collection of individual modules that can be independently controlled. The group consists of active elements, called links, which are 3-DOF manipulators capable of attaching to~detaching from the passive elements (cubes) acting as connectors. The cubes can be oriented and posi...
متن کاملI(CES)-Cubes: A Modular Self-Reconfigurable Bipartite Robotic System
In this manuscript, we introduce I(CES)-Cubes, a class of three-dimensional modular robotic system that is capable of reconfiguring itself in order to adapt to its environment. This is a bipartite system, i.e., a collection of (i) active elements capable of actuation, and (ii) passive elements acting as connectors between actuated elements. Active elements, called links, are 3-DOF manipulators ...
متن کاملA Modular Self-Reconfigurable Bipartite Robotic System: Implementation and Motion Planning
In this manuscript, we discuss I-Cubes, a class of modular robotic system that is capable of reconfiguring itself in 3-D to adapt to its environment. This is a bipartite system, i.e., a collection of (i) active elements for actuation, and (ii) passive elements acting as connectors. Active elements (links) are 3-DOF manipulators that are capable of attaching/detaching from/to the passive element...
متن کاملA Hierarchical Motion Planning Strategy for a Uniform Self-Reconfigurable Modular Robotic System
This paper describes a multi-layered hierarchical motion planning strategy for a class of self-reconfigurable modular robotic systems, I-Cubes. The approach is based on the synthesis of motion on the basis of metacubes, which have a particular structure possessing 8 Cubes and 16 Links. The developed strategy organizes the metacube motions and the corresponding cube-level motions. At the lowest ...
