Moco goals for average speed in cycling model

Hello, I'm currently working on a project involving a human model (with joint torques) connected to a crank, capable of pedalling from position 0 to 360 degrees. I can successfully predict pedal motion using MocoFinalTimeGoal as the target goal. Now, I want to explore a different target: average cra...

Re: apply transform to mesh file frame

Hello there! Even though this post is a bit old, I wanted to share a solution I recently came up with for this issue. Mesh geometry, which represents only the visual aspect of objects, cannot be rotated directly in OpenSim. However, you can work around this limitation by creating a Frame related to ...

Is there a way to remove a WeldJoint using the API?

Hello everyone, I would like to know if there is a way to remove a WeldJoint from a model using the API. I have successfully added the WeldJoint using the following code snippet: Code joint = osim.WeldJoint("joint_1_2", model.getBodySet().get("body1"), osim.Vec3(0, 0, 0), osim.Vec3(0, 0, 0), model.g...

Re: Question about turning a muscle-driven model into a torque-driven model

I'm not an expert here, but I know it is possible to plot the actuation from your external actuators. If you take a look at Moco examples, you can probably find that

Re: Question about turning a muscle-driven model into a torque-driven model

Hi Chen, I find it a bit hard to understand completly without some extra information from your code. For example, it's crucial to ensure that the initial joint angles, velocities, and external forces are correctly specified to achieve the desired behavior. However, doesn't your model contains gravit...

Re: study.visualize(predict_solution) show only a white background

Hi Mohammadreza, That was a great suggestion, but unfortunetly it didn't work... I tried: osim.ModelVisualizer.addDirToGeometrySearchPaths('C:\OpenSim 4.4\Geometry') and also osim.ModelVisualizer.addDirToGeometrySearchPaths('C:\OpenSim 4.4\Geometry') current_directory = os.getcwd() data_folder_path ...

Re: Moco Visualize erros

Hi Azarang Asadi, I know it has been a while, but have you been able to solve that?
I have been having similar problems.

study.visualize(predict_solution) show only a white background

Hello everyone, I am facing an issue with visualize(predict_solution), it shows an all-white screen. I have run all Moco examples with the visualiser without any issues. Moreover, when I open the GUI, load the model and then load my solution (.sto), it works fine. The problem is with running the vis...

Re: Control strategies for functional electrical stimulation (FES) cycling Public Forum

That is the final opensim model that will be used by opensim. It follows a specific structure that you can see here: https://simtk.org/api_docs/opensim/api_docs/classOpenSim_1_1TorqueActuator.html You can directly edit the .osim file, but I created using other functions from the API, as you can see ...
