Academia, Industry and Government are investigating the reliability to use the real time kinematic (RTK) Global Navigation Satellite System (GNSS) techniques for centimetre level positioning of many existing and emerging applications. These include for instance mobile mapping and airborne laser scanning systems. The classical RTK methodology allows for an operational distance between the refere...

A bstract We study the impact of third-order QCD corrections for several kinematic moments inclusive semileptonic B decays, to first order in 1 /m b expansion. consider four charged-lepton energy E R spectrum, total leptonic invariant mass q 2 and hadronic $$ {M}_X^2 M X 2 ...

We present a computational kinematic theory of higher pairs with multiple contacts, including simultaneous contacts, intermittent contacts, and changing contacts. The theory systematizes singleand multiple-contact kinematic analysis by mapping it into geometric computation in configuration space. It derives the contact conditions, contact functions, and relations between contacts from the shape...

We propose a new two -degree of freedom para llel mechanism for a haptic device and will refer to the mechanism as the SenSation. The SenSation is designed in order to improve the kinematic performance and to achieve static balance. We use the pantograph mechanisms in order to change the location of active joints, which leads to transform a direct kinematic singularity into a nonsingularit y. T...

In this paper, we discuss the problem of how a free-floating space manipulator can be mapped to a conventional, fixed-base manipulator which preserves both its dynamic and kinematic properties. This manipulator is called dynamically equivalent manipulator (DEM). The DEM concept not only allows us to model a free-floating space manipulator system with simple, well-understood methods, but also ca...

This paper uses the kinematic mapping into the image space of spherical displacements to design a cooperating spherical robot system for workpiece orientating. The kinematic chain formed b y the cooperating robots grasping the workpiece forms a multi degree of freedom closed chain which is also known as a robotic mechanism. The spherical robots considered are spherical RPR open chains and they ...

I n this work, we consider a class of robotic manipulators generally termed “hyper-redundant”. Spec<fically, we seek to examine some 0.f the kinematic properties of ‘%ontinuum” hyper-redundant robots. Unlike the case with rigidlink’robots, there is n o commonly accepted formula ,for describing continuum robot kinematics. Although these manipulators are continuously flexible, they are actuated w...

A kinematic adaptive neuro-controller for trajectory tracking of nonholonomic mobile robots is proposed. The kinematic adaptive neuro-controller is a real-time, unsupervised neural network that learns to control a nonholonomic mobile robot in a nonstationary environment, which is termed Self-Organization Direction Mapping Network (SODMN), and combines associative learning and Vector Associative...

This work presents the first results of an experiment aiming to derive a high resolution Digital Terrain Model (DTM) by kinematic GPS surveying. The accuracy of the DTM depends on both the operational GPS precision and the density of GPS samples. The operational GPS precision, measured in the field, is about 10 cm. A Monte Carlo analysis is performed to study the dependence of the DTM error on ...
