Mobility analysis of variable geometry trusses
… in terms of increased strength and rigidity. Variable geometry trusses (VGTs) are a special class of parallel trusses. Literature on VGTs has covered many interesting problems, yet there has been no conscious effort to formulate a definition for a VGT. The major emphasis of this thesis is …

Design of a robotic manipulator using variable geometry trusses as joints
… workspace restrictions. The introduction of Variable Geometry Trusses (VGT’s) represents an opportunity to overcome this limitation. The lack of stiffness in many serial manipulators is primarily due to compliance at the joints. The disadvantage of the series connected device include …

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 …

A planar comparison of actuators for vibration control of flexible structures
… of the structure. A new class of actuators, variable geometry trusses (VGT's), has been recently introduced. These actuators are actually built into the structure, and they operate by varying their link lengths to apply forces to the structure or to change the shape of the structure itself. …

Positional control strategies for a modular, long-reach, truss-type manipulator
… of modular, long-reach, truss-type manipulator. Variable Geometry Trusses (VGT’s) are used to construct a reconfigurable manipulator system in which all primary members are loaded in pure tension or compression. Each module of the manipulator system is either a static truss link or one of several …

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 …
