Structural Synthesis of 3-DoF Spatial Fully Parallel Manipulators
(Intech Europe, 2014-07-16)
In this paper, the architectures of three degrees of freedom (3-DoF) spatial, fully parallel manipulators (PMs), whose limbs are structurally identical, are obtained systematically. To do this, the methodology followed ...
Control Distribution of Partially Decoupled Multi-level Manipulators with 5 DOFs
(Cambridge University Press, 2017-02-01)
Multi-level manipulators are those mechanisms in which two or more levels, that de ne the main chain of the manipulator, are joined in parallel to each other. Besides, each level is linked to the base in parallel by ...
A robot for non-destructive testing weld inspection of offshore mooring chains
(SAGE Publications Inc., 2018-05-09)
Welding flaw detection is a key step in manufacturing many components. In offshore chains, every link is manufactured from a steel bar that is bent and the ends joined by flash butt welding. Ultrasonic inspection of the ...
A robot for welding inspection in offshore mooring chains
In this paper, the authors present the CIRUS robot. This automatic system uses a combination of pulse-echo and pitch and catch ultrasonic strategies for the inspection of the welded area of mooring chain links in an automatic ...
