Abstract
In the field of human-robot interaction, surface electromyography (sEMG) provides a valuable tool for measuring active muscular effort. While numerous studies have investigated real-time control of upper extremity exoskeletons based on user intention and task-specific movements, the prediction of body joint positions based on EMG features has remained largely unexplored. In this letter, we address this gap by proposing a novel approach that leverages Convolutional Neural Networks and Long-Short-Term Memory (CNN-LSTM) models to generate exoskeleton joint trajectories. Our methodology involves collecting data from three channels of EMG and three degrees-of-freedom (DoF) joint angles and enables us to position control a pneumatic cable-driven upper-limb exoskeleton, thereby assisting users in various tasks. Through extensive experimentation, our intention-based model demonstrates robust performance across different speeds and is capable of detecting variations in payload and electrode placement. The empirical results yielded from our study underscore the efficacy of our approach, particularly in reducing the EMG levels of the user during different tasks by providing exoskeleton assistance as needed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
