Re: Exoskeleton Modeling Approach

Ajay, Thank you for your reply. I have actually moved back to using a combined model, which I have attached by using point constraints. In order to get the constraints to work, I am only using 1 constraint between the exoskeleton torso to the human torso. This represent a connection at the shoulders...

Exoskeleton Modeling Approach

Hello, I am attempting to model the interaction between an exoskeleton and a human model. The particular exoskeleton I am modeling only attaches to the human at the feet and the shoulders, although I may also try to attach it at the hip. I'm using the gait2392 model for the human and I have created ...

Re: toes shaking during CMC

Neshu, For CMC analysis with the gait2392 model, it is advised to lock the subtalar and mtp joints, as I have heard that there are not enough muscles to properly control them in the model. I have had the same issues and locking those joints greatly improved my results. You will also probably have to...

Crash when running specific case in RRA

Hello, I have been having a repeated issue with running RRA. I am attempting to simulate the effects of an exoskeleton attached to a human body. I am using the Simbody 2392 gait model as the human body and a custom made model for the exoskeleton. To model the attachment points I am experimenting wit...
