I was exploring the Spring Mass Damper 2 custom program for Dexterit 3.5 and I was wondering how I can change the resistance that it puts against the subject. I was looking at the simulink model and I clicked on the Force Generator Block. Could I change the resistance in the Spring force? Also, can a UDP be applied so that I can change the resistive force parameter before starting new trials? My main goal is to change the resistance the robotic arm applies to the subject as they move from point A to B as I start a new trial.
