    Dataset for 'Reducing Sensor Configuration for Data-Driven Shoulder Load Estimation for Exoskeleton Control'

    No full text
    This paper investigates the role of various sensors in estimating shoulder loads during manual manipulation tasks in the context of exoskeleton control. The sensors examined include textile-integrated electromyography (EMG) sensors forthe trapezius, deltoids, biceps, and forearm muscles; inertial measurement units (IMUs) on key body segments such as the pelvis, shoulder, upper arm, and forearm; and pressure-sensing insoles. The objective is to reduce the sensor configuration for predicting the internal torque exerted on the shoulder in the sagittal plane. To achieve this, a study involving nine subjects manipulating dumbbells in the sagittal plane was conducted. The protocol encompasses four static positions as well as isolated elbow and shoulder flexions. Further, four distinct machine learning model architectures were trained, systematically omitting one sensor at a time. The significance of each sensor was evaluated by assessing the impact of its omission on the predictive correlation using cross-validated R2 scores. Consequently, a top-five sensor configuration was identified and compared against configurations based solely on domain knowledge and the full sensor array. The configuration proposed in this study achieved a correlation of R2 = 0.83 in predicting shoulder loads, slightly surpassing the performance of the full sensor setup (R2 = 0.82) and outperforming the domain knowledge-based (DKB) setup (R2 = 0.63). All metrics are determined in a leave-one-subject-out cross-validation (loso-cv) training strategy.Physical strain in the construction trade is enormous, leading to frequent absences from work and occupational disability. A lack of young talent exacerbates the shortage of skilled workers in the construction industry. The aim of the “HEXOBAU” project is therefore to develop a user-friendly, lightweight, hydraulic exoskeleton that supports craftsmen in lifting, overhead work, and other strenuous tasks. The project is funded by the Invest BW funding program of the state of Baden-Württemberg.The Dataset consists of raw and processed .csv-files and is additionally pickled in .pkl-files for use in python

    Instrumented Impact Test Data for CFPA6 Crash Box Systems

    No full text
    This dataset contains time-resolved measurements from crash tests performed on three crash box systems (specifically numbered 5, 6, and 7). The data includes various physical quantities recorded during the impact events. Each quantity is available for two measurement points and includes both raw and filtered signals. The impactor was instrumented using two KYOWA damped accelerometers. The acceleration data were used to calculate force, displacement, and the energy absorbed during impact. A CFC180 filter was applied to the acceleration signals for data smoothing and noise reduction. The columns in the dataset are as follows: Impactor Acceleration 1 – Raw acceleration data from the first impact sensor. Filtered Impactor Acceleration 1 – Filtered acceleration data (CFC180) from the first sensor. Impactor Acceleration 2 – Raw acceleration data from the second impact sensor. Filtered Impactor Acceleration 2 – Filtered acceleration data (CFC180) from the second sensor. Average Impactor Acceleration – Mean of the filtered acceleration data from both sensors. Velocity – Integrated velocity profile of the impactor. Displacement – Integrated displacement profile of the impactor. Force from Impactor Acceleration 1 – Force calculated using the first acceleration signal and impactor mass. Force from Impactor Acceleration 2 – Force calculated using the second acceleration signal and impactor mass. Average Force – Mean of the forces derived from both sensors. Energy – Energy absorbed by the structure, obtained by integrating the force over displacement. Three types of crashbox samples were tested (see also Fig. 8): Crash box 6: Fully riveted crash box system Crash box 7: Crash box system without rivets Crash box 5: Fully riveted crash box system with an aluminium plate (176 × 78 × 3 mm) welded on the top ringThe research leading to these results has received funding from the Horizon EU Programme under grant agreement No. 101069600 and UKRI grant agreements No. 10047227 and No.10047305 (SALIENT Project)

    Parameter Harmonization of Jiles-Atherton model Variants

    No full text
    This dataset provides the numerical results and optimization routines used to harmonize different Jiles–Atherton (JA) hysteresis model variants. The goal of the study was to determine whether parameter sets of one JA formulation can be transformed such that another formulation reproduces the same B(H) behaviour.This dataset contains the numerical routines and optimization results used to establish parameter mappings between different Jiles–Atherton (JA) model variants. Synthetic B(H) curves were first generated for a selected reference model over multiple magnetic-field amplitudes. These curves served as target data for a Differential Evolution (DE) optimization scheme implemented in MATLAB. For each target curve, the parameters of the alternative JA models were optimized such that their simulated B(H) trajectory matched the reference model
