ClutchedPathSpring

[Nithin Kurup]

Hi,
I have a doubt regarding the use of ClutchedPathSpring. In this I noted that, both the optimal force and the stiffness values need to be given, unlike in path actuator where only optimal force and in other passive springs, in which stiffness is only needed.
The tension produced in ClutchedPathSpring is a function of the stiffness and stretch of the spring (control 0-1 max), so what does the optimal force value in this context mean and how is it related to the stiffness.
Thanks,

Nithin

Hi,

In cases like this it is a good practice to dig into the source code. The optimal force is irrelevant to the ClutchedPathSpring dynamics and is there because it was inherited from the PathActuator object.

Dear Stanev,

Yes , I believe you are correct, it is irrelevant. Thank you so much for your reply.

Thanks again,
