Re: Linear Velocity Constraint or Goal
Sorry to resurface an old post, but I cannot seem to identify the units for speed in Moco.

Re: MocoTrack: Muscle Driven vs. Actuator Driven Problem
As a follow up: Does a coordinate actuator integrated directly into the model work like a reserve actuator (implemented using: ModOpAddReserves)? Do the reserve actuators added using ModOpAddReserves only activate if the coordinate actuator does not generate sufficient force, or are they used simult...

MocoTrack: Muscle Driven vs. Actuator Driven Problem
Hello, Question about MocoTrack, and Moco in general. Let's say I am trying to drive a specific motion using a set of muscles. I am only interested in a particular subset of muscles, but more muscles/actuators may be required to actually initiate the motion I desire. If I am using MocoTrack, but I a...

Re: Performance Issues Out of Nowhere
Thanks so much for the suggestions.
I currently do not have any residual actuators.
How necessary are they to getting a suitable convergence and are there exampled I can draw from to implement these successfully?

Re: Performance Issues Out of Nowhere
Thanks for the response. I actually managed to fix the issue, but now I have other problems. In my Tracking simulation (where I provide kinematic data as reference), I am really struggling to get it to converge, and as time and iterations go on, the tracking gets worse... I have been working on this...

Performance Issues Out of Nowhere
Hello, I am running an instance of MocoTrack on MATLAB, and suddenly, the simulation has been taking forever to run, even initialize, despite me not having made significant changes to the code. For example, my last simulation took over 55 hours over the weekend, and did not even converge. I tried lo...

Re: Linear Velocity Constraint or Goal
Thanks for all the help Nick. I see your responses across a number of forum posts, and the efforts are very much appreciated. Regarding my question, is there a way to specify a direction for my linear velocity? For example, if I want the hand to reach a final velocity along the positive x-axis? Than...

Re: Linear Velocity Constraint or Goal
Nick, you are a lifesaver!
But unfortunately, append seems to require a text input. I used add instead of append and that seemed to work, but wanted to check and confirm if that was a viable solution.
Thanks again,
Cedric

Re: Linear Velocity Constraint or Goal
Thank you Nick! I am having an issue with the following line: setEndpointConstraintBounds(MocoBounds(10)); Where it says; Incorrect number or types of inputs or outputs for function setEndpointConstraintBounds. From my understanding, setEndpointConstraintBounds requires a vector with the length equa...

Linear Velocity Constraint or Goal
I am attempting to constrain the motion of my model so that the final velocity of the hand is a certain linear speed as such: problem.setStateInfo('/bodyset/hand/speed', [0,50], 0, 10); I am realizing that the setStatInfo does not recognize a body, and requires a joint speed to constrain. The proble...
