Differentially-Clutched Series Elastic Actuator for Robot-Aided Musculoskeletal Rehabilitation
Bibliographic record
Abstract
Series elastic actuators have proven to be an elegant response to the issue of safety around human-robot interaction. The compliant nature of series elastic actuators provides the potential to be applied in robot-aided rehabilitation for patients with upper and lower limb musculoskeletal injuries. This paper proposes a new series elastic actuator to be used in robot-aided musculoskeletal rehabilitation. The actuator is composed of a DC motor, a torsion spring, and a magnetic particle brake coupled to one common output shaft through a differential gear. The proposed topology focuses on three types of actuation modes most commonly used in rehabilitation, i.e., free motion, elastic, and assistive/resistive motion. A dynamic model of the actuator is presented and validated experimentally and the ability of the actuator to follow a reference torque is shown in different experimental scenarios.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
