Measurement assisted robotic edge deburring of aero engine components [PDF]
, 2010 Aero engine components are often subjected to high stress levels and vibrations during operation. The mechanical integrity of these machined components may be compromised by the presence of burrs and sharp edges.

Bistable Networks Enable Complex Shape Changes. [PDF]
Adv Sci (Weinh)Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

A metaheuristic approach to optimal morphology in reconfigurable tiling robots
Complex & Intelligent Systems, 2023 AbstractReconfigurable robots are suitable for cleaning applications due to their high flexibility and ability to change shape according to environmental needs. However, continuous change in morphology is not an energy-efficient approach, with the limited battery capacity.

Complexity of Tiling a Polygon with Trominoes or Bars [PDF]
, 2017 We study the computational hardness of the tiling puzzle with polyominoes, where a polyomino is a rectilinear polygon (i.e., a polygon made by connecting unit squares.) In the tiling problem, we are given a rectilinear polygon P and a set S of ...

Computer-assisted robotic tiling of mosaics
Robotica, 2004 This paper describes the development of a system that is capable of tiling mosaics using a robot according to requirements of the individual customer. The art of mosaic, in one form or another, has been practiced manually for thousands of years. Modern developments in materials and production techniques could be found as evidence that mosaic is very ...

A nonlinear disturbance observer for robotic manipulators [PDF]
, 2000 A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...
