Strategy
Experimental data
- Two different data were collected from a same subject.
- One gait cycle of loaded walking (From left toe off to next left toe off)
- One gait cycle of unloaded walking (From left toe off to next left toe off)
- The subject didn't wear a suit and walked freely.
...
- walking speeds are identical in both cases
...
- Mass of the load for loaded walking was 38kg.
...
- Data type
- Marker position data
- Ground reaction force data
- Subject

Modeling
To simulate the movement of exosuit wearer, the first thing to do is to create a model which can replicate a real subject as possible as we can. Before I created our model with active actuator on it, I had the generic gait model in opensim to go through the basic steps of modeling procedure in OpenSim. By doing so, I could make my model dynamically consistent to the experimental data. And then, I added actuators and metabolic cost probes to the model.
