Aim: 

• Design a lightweight and compact SEA for wearable exoskeletons

Technical Problem: 

• SEA is too heavy and large due to torsional spring

Novel Approach:

• Use spring steels to replace the torsional spring

• Apply machine learning to optimize the dimension of spring steel

Finite-element Analysis (FEA) Simulation Result

• A suitable dimension can be found with desired Max. Von-Mises stress and Angular deformation

Mechanical design with 3D CAD model

FEA analysis with ANSYS

Machine learning technique (Regression)
