Hello,
I want to simulate the effect of an exoskeleton by using MATLAB. I have added four coordinate actuators in the model. I'd like to simulate the motion of these four actuators in MATLAB. I wonder which function should I use? Should I use forward kinetic tools or something else?
Thanks a lot

Hello, As of version 4.0, the specification of objects/components in the model file has been made more strict, and a full path (e.g. /bodyset/tuigan1) is now required where only name (tuigan1) was needed in the past. When you refer to a frame by name only within a constraint set, it looks for the f...

Hello all, I tried to add a weld constraint to my model ,but I encountered some problems. When I write the code like this <ConstraintSet name="constraintset"> <objects> <WeldConstraint name="tuigan1_qiufu"> <frame1name>qiufu1_offset</frame1name> <frame2name>tuigan1_offset</frame2name> </WeldConstrai...

Sorry I didn't notice that

Hello, all! I tried to add a weld constraint to my model, but if I write the code like this: <ConstraintSet name="constraintset"> <objects> <WeldConstraint name="tuigan1_qiufu"> <frame1name>qiufu1_offset</frame1name> <frame2name>tuigan1_offset</frame2name> </WeldConstraint> </objects> </ConstraintSe...

Hello, The underlying multibody system of an OpenSim model is a Tree (you can see this in the Application/GUI Topology View). As such if you want to have loops/connections that breaks the Tree structure, then you'll have to do it with Constraints. Please check the doxygen documentation here https:/...

Hello all, I'm trying to add a 3D model to the model Gait2392. Since my model is base on parallel robot, I have two joints which has the same child frame. And when I try to open it in Opensim, the software has no response. I wonder if it's because that there can't be two joints who have the same chi...
