Hello, I was wondering if there is a way to create a "circular wall", i.e., a boundary defined as a distance from a given point, which if crossed, would activate a force preventing further radial movement toward the boundary ? I am using an NHP exoskeleton kinarm.  Thanks for your help !  Nicolas

Yes, that is possible.

The way to do it would be to have a logical check where you are detecting if the hand is outside the circle and then create a spring force
f = -kx that pushes you to the centre of the circle.

We don’t have a sample task that directly pertains to that but you could look at our force channel sample task https://kinarm.com/task/force-channel/ where a spring force is used to bring you back to the force channel if your hand moves out of it.

That was a bit brief of a description, so please feel free to let me know if you have any questions.

Cheers,
Koloman
