Kinematic Calibration by Means of a Triaxial Accelerometer

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

Kinematic Caiibration by Means of a Triaxial Accelerometer

A new method for kinematic calibration of a robot zs presented, based on triaxial measurement of acceleration by a sensor fixed to the robot end-point. The kinematic parameters are evaluated by means of a series of simple tests ( two for each jo in t ) . In these tests each jo in t , except the one under consideration, is kept fired. Acceleration and encoder output are then acquired. Simulation...

Review and Comparison of In-field Calibration Methods of Accelerometer Based on Gravity Vector

Considering the wide applications of accelerometers to determine position and attitude and due to reducing of accuracy of this sensors because of some errors, this paper discusses the calibration of accelerometers. Also because the traditional calibration methods are very time consuming, costly and need precision laboratory equipment, in-field calibration methods are recommended which are simpl...

Correlation between accelerometry and clinical balance testing in stroke

[Purpose] The purpose of this study was to determine the correlation between the Berg Balance Scale (BBS) and acceleration of postural sway in the Clinical Test of Sensory Interaction and Balance (CTSIB) by using a triaxial accelerometer for quantitative assessment. [Subjects and Methods] Twenty-seven stroke patients participated in this study. Balance ability was evaluated with the BBS, and po...

Calibration of an Inertial Accelerometer using Trained Neural Network by Levenberg-Marquardt Algorithm for Vehicle Navigation

The designing of advanced driver assistance systems and autonomous vehicles needs measurement of dynamical variations of vehicle, such as acceleration, velocity and yaw rate. Designed adaptive controllers to control lateral and longitudinal vehicle dynamics are based on the measured variables. Inertial MEMS-based sensors have some benefits including low price and low consumption that make them ...
