Dynamic Behaviour and Stability Analysis of Multibody Haptic Systems
Bibliographic record
Abstract
To investigate the effects of mechanical design parameters on the performance of force feedback haptic devices, a representative dynamic model of the system is required. In this paper, the experimental investigations conducted on a 2DoF haptic device revealed that flexibility associated with the joints reduced the stable domain of operation considerably. Therefore, dynamic model of the investigated mechanism including the joint flexibility and physical damping is considered. The stability boundaries achieved by using the proposed flexible joint model is in good agreement with experimental results. A simplified model of the system is then developed employing a decomposition proposed in [1]. It is shown that the stability limits obtained by this simplified model give a slightly conservative but close estimate to the stability boundaries of the higher DoF flexible joint model. Such a simplified and experimentally validated model can be used for impedance-type haptic devices. The developed model makes it possible to investigate the effect of different mechanical parameters on the performance of multibody haptic systems.

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.
