Kinodynamic planning attempts to solve a robot motion problem subject to simultaneous kinematic and dynamics constraints. In the general problem, given a robot system, we must nd a minimal-time trajectory that goes from a start position and velocity to a goal position and velocity while avoiding obstacles by a safety margin and respecting constraints on velocity and acceleration. We consider th...

High-performance AC and DC industrial servodrives use standardized motion control algorithms. The algorithms are based on common feedback sensing methods (digital position measurement via encoders or resolvers) and a common assumption that the electromagnetic torque dynamics are substantially faster than the motion control dynamics desired. The vast majority of these motion control algorithms c...

Vertical optokinetic nystagmus (OKN) and optokinetic afternystagmus (OKAN) were recorded in 6 normal subjects using the magnetic scleral search coil technique in order to reevaluate the up-down symmetry of these responses. The effects of body position relative to gravity were investigated by comparing OKN and OKAN elicited with the subjects in an erect and in a lateral side position. No consist...

OBJECTIVE To quantify velocity dependent and position related properties of increased muscle tone measured during a constant velocity stretch. METHODS Elbow flexors were vertically stretched under four different velocities (40, 80, 120, and 160 degrees /s) through a 75 degrees range of motion in 12 patients with hemiparesis, 16 with parkinsonism, and 12 normal controls. From reactive torque m...

We use the quantum Langevin equation as a starting point to study response function, position–velocity correlation function and velocity autocorrelation of charged Brownian particle in presence magnetic field linearly coupled heat bath via position coordinate. two models – Ohmic model Drude make detailed comparison various time–temperature regimes. For both models, there is competition between ...

In this paper, a technique for error estimation in a global positioning system and inertial navigation system (GPS/INS system) based on a low-cost inertial measurement unit (IMU) is offered. This technique is composed of Wavelet Transform (WT) and Adaptive Fuzzy System (AFS). The wavelet decomposition is used to de-noise the position and velocity components of the GPS and INS outputs. An AFS is...

Visual tracking of moving objects requires prediction to compensate for visual delays and minimize mismatches between eye and target position and velocity. In everyday life, objects often disappear behind an occluder, and prediction is required to align eye and target at reappearance. Earlier studies investigating eye motion during target blanking showed that eye velocity first decayed after di...
