Friction in a non-motor-enabled joint

Post by MattDerry » 11 Jul 2013, 20:05


I'm continuing in my saga towards actually being able to grasp the handle of the crank for the project I'm working on. I have the model dynamics working pretty well on the arm itself, but now I'm looking at the crank that is to be turned. It's basically 3 links with 2 joints that don't have the "motor enabled" checkbox checked. I'm wondering if there is a way I could increase the rotational friction in these joints without enabling them? I saw the "Engine Specific Properties" dialog, but I'm not sure what those parameters do and I've only had marginal success in finding the answers. Thanks in advance!

Hello Matt,

just turn the motor on (Motor enabled), make sure the control loop is disabled (leave unchecked Control loop enabled), set a Target velocity of 0, and adjust the force torque (Max. torque/force) until you have the desired friction.
