Perceptual Comparisons of Viscoelastic Renderings: Fractional- vs Integer-Order Models
Gorkem Gemalmaz, Harun Tolasa, Volkan Patoglu
Realistic haptic rendering of viscoelastic materials requires reproducing time-dependent behaviors such as creep and stress relaxation, which arise from the material's inherent mem…
Haptic Rendering of Fractional-Order Viscoelasticity: Passivity and Rendering Fidelity
Gorkem Gemalmaz, Harun Tolasa, Volkan Patoglu
Haptic rendering of viscoelastic materials that exhibit creep and stress relaxation is crucial for many applications, such as medical training with realistic biological tissue mode…
Human-in-the-Loop Pareto Optimization: Trade-off Characterization for Assist-as-Needed Training and Performance Evaluation
Harun Tolasa, Volkan Patoglu
During human motor skill training and physical rehabilitation, there is an inherent trade-off between task difficulty and user performance. Characterizing this trade-off is crucial…
Active Learning of Fractional-Order Viscoelastic Model Parameters for Realistic Haptic Rendering
Harun Tolasa, Gorkem Gemalmaz, Volkan Patoglu
Effective medical simulators necessitate realistic haptic rendering of biological tissues that exhibit viscoelastic material properties, such as creep and stress relaxation. Fracti…
Passive Realizations of Series Elastic Actuation: Effects of Plant and Controller Dynamics on Haptic Rendering Performance
Celal Umut Kenanoglu, Volkan Patoglu
We introduce minimal passive physical equivalents of series (damped) elastic actuation (S(D)EA) under closed-loop control to determine the effect of different plant parameters and…
Simulation-based multi-criteria comparison of mono-articular and bi-articular exoskeletons during walking with and without load
Ali KhalilianMotamed Bonab, Volkan Patoglu
Developing exoskeletons that can reduce the metabolic cost of assisted subjects is challenging since a systematic design approach is required to capture the effects of device dynam…
