Kinematic analysis and animation of a variable geometry truss robot
… a parallel, closed-loop manipulator known as the Variable Geometry Truss or VGT for short. Widely recognized as adaptive or collapsing structures for space and military applications, VGTs have not received due consideration as robotic manipulators. VGTs undoubtedly represent an important sector of …

Design and construction of a double-octahedral variable geometry truss manipulator
… deals with the design and construction of a variable geometry truss (VGT) of the double-octahedral (pyramid-pyramid) geometry. The truss is expected to be the focus of several experimental research projects. In this thesis, a kinematic model is formulated, and the forward and inverse …

Shape control of high degree-of-freedom Variable Geometry Truss manipulators
Variable Geometry Trusses (VGT’s) can be used as the fundamental building blocks in constructing long-chain, high degree-of-freedom manipulators. This thesis focuses on the kinematics of two such manipulators. It also illustrates how the concept of shape control can be applied to simplify the …

The solution of variable-geometry truss problems using new homotopy continuation methods
A VGT or Variable-Geometry Truss can be thought of as a statically determinate truss that has been modified to contain some number of variable length members. These extensible members allow the truss to vary its configuration in a controlled manner. VGTs are often symmetric. constructed of …

Kinematic Analysis of Tensegrity Structures
… (cables). Tensegrity structures can be used as variable geometry truss (VGT) mechanisms by actuating links to change their length. This paper will present a new method of position finding for tensegrity structures that can be used for actuation as VGT mechanisms. Tensegrity structures are …

Shape design using intrinsic geometry
… a methodology of shape synthesis using intrinsic geometry concepts for engineering design of two-dimensional and three-dimensional curves as well as three-dimensional surfaces. Using concepts of intrinsic geometry of curves, the shape of a curve can be defined in terms of intrinsic parameters such …

A study of isostatic framework with application to manipulator design
Isostatic frameworks are statically determinate trusses that are self contained (Le. they exist independent of support or foundation). Isostatic frameworks have been widely used as supporting structures, and recently they have been used as the structure for parallel manipulators. These truss-based …
