Nested Reconfigurable Robots: Theory, Design, and Realization

open access: yesInternational Journal of Advanced Robotic Systems, 2015
Rather than the conventional classification method, we propose to divide modular and reconfigurable robots into intra-, inter-, and nested reconfigurations.

Common Unfoldings of Polyominoes and Polycubes [PDF]

open access: yes, 2011
This paper studies common unfoldings of various classes of polycubes, as well as a new type of unfolding of polyominoes. Previously, Knuth and Miller found a common unfolding of all tree-like tetracubes. By contrast, we show here that all 23 tree-like pentacubes have no such common unfolding, although 22 of them have a common unfolding. On the positive

Level and pseudo-Gorenstein path polyominoes

open access: yes, 2023
We classify path polyominoes which are level and pseudo-Gorenstein. Moreover, we compute all level and pseudo-Gorenstein simple thin polyominoes with rank less than or equal to 10.

Enumeration of generalized polyominoes

open access: yes, 2008
As a generalization of polyominoes we consider edge-to-edge connected nonoverlapping unions of regular k-gons. For n ≤ 4 we determine formulas for the number ak(n) of generalized polyominoes consisting of n regular k-gons. Additionally we give a table of
