(PDF) Model-Based Estimation Of Ankle Joint Stiffness

(PDF) Model-Based Estimation Of Ankle Joint Stiffness This library provides an implementation of the volumetric stiffness field (vsf), a model for heterogeneous deformable objects that enables real time estimation and simulation. This work tackles the challenge of stiffness estimation in articulated soft manipulators, and it proposes an innovative solution adding value to the previous research by removing the necessity for force/torque sensors and generalizing to multi degree of freedom robots. In this study, we propose an emg driven musculoskeletal model that relies on a set of closed form equations that enables the person specific tuning of musculoskeletal features that influence stiffness at multiple anatomical levels, i.e., joint, muscle, and tendon levels. In this study, we proposed a method for energy conservation based online tuning of the analytical model using an artificial neural network (ann) to address these challenges.

In this study, we proposed a method for energy conservation based online tuning of the analytical model using an artificial neural network (ann) to address these challenges. First, we propose a new emg driven model that can be calibrated at the joint torque and stiffness levels simultaneously during dynamic ankle joint rotations. we hypothesize this will improve joint stiffness estimation with respect to torque only calibrated models. This library provides an implementation of the volumetric stiffness field (vsf), a model for heterogeneous deformable objects that enables real time estimation and simulation. The method estimates an object’s force response given robot force or torque measurements using a novel volumetric stiffness field representation and point based contact simulator. Secondly, we present a model based online esti mation technique to estimate the 7 dimensional complete joint stiffness in various arm poses and activation levels of the two dominant arm muscles that correspond to the geometric and volume modifications of the joint stiffness profile, respectively.
