Re: Using Moco to calculate the kinematics of a DOF/coordinate
Hi Nick, and thanks again for all the effort! With state tracking goal being zero, did you mean objective_state_tracking=0.000000? I have never seen anything else than zero in the mocotrack_solution.sto file. I removed the ElasticFoundationForces. I corrected the value names, but that didn't help. A...

Re: Using Moco to calculate the kinematics of a DOF/coordinate
Hi Nick, The trajectories at least look very much the same, and very different from the intended one. But the console output is, apart from the timing exactly the same. Here a complete diff of 2 sessions 4c4 < [info] Mon Feb 14 20:52:11 2022 --- > [info] Mon Feb 14 20:53:26 2022 7c7 < state_tracking...

Errors and warning when using a model with muscles
Hello List, I have a relatively simple model, 5 bodies and 5 joints only using generalized coordinate actuators. This works mostly fine with CMC. But when I added some muscles there are a few problems. p_muscle.png The model represents a "leg" on a box, and the leg consists of upper leg, lower leg a...

Re: Using Moco to calculate the kinematics of a DOF/coordinate
Still no luck regrettably. I increased the global_state_tracking_weight to 100. Also did modelProcessor.append(osim.ModOpAddReserves(250)) to add actuators, but is this actually relevant because the model has no muscles and already coordinate actuators? Finally set all weights for the actuators to n...

Re: Using Moco to calculate the kinematics of a DOF/coordinate
Hi Nick, I created a script pusherMocoTrack.py starting from the function muscleDrivenStateTracking from the example3DWalking/exampleMonoTrack.py. See github, it is also attached below. I changed the model, and did not load an external load. Also I tried to set the proper weights for the coordinates...

Using Moco to calculate the kinematics of a DOF/coordinate
Hello list, I understood that it should be possible to use Moco to solve problems where not all DOF's are given in that it will calculate the unknowns DOF's. In my use case I have a model consisting of a "person" sitting on a box ("boat") that tries to push this box over the ground ("water"). The mo...

Re: Some issues with installing on Linux
You're correct, setting /etc/default/locale to
LANG=en_US.UTF-8
LANGUAGE="en_US:en"
solved the issue!
LANG=en_US.UTF-8
LANGUAGE="en_US:en"
solved the issue!

Re: Some issues with installing on Linux
The problem on Ubuntu does NOT occur if you use the command line tool, as in:
Code: Select all
opensim-cmd run-tool push_Setup_IK.xml

Re: CMC tool with slow target does not work properly
Simplified the model further, to 11 coordinates. Also 2 of the 3 kinematics chain loops are removed. I now have 2 models that only differ in one body and one joint. bootbaan_simplified.png This is the model where the error occurs, which starts with a wild spinning of the upper arm. When the, single,...

CMC tool with slow target does not work properly
Hello List, I created a number of models and created trajectories for it. There are no muscles involved, but a few constraints. I use the CMC-tool in the slow target mode. For simple models it works fine, you just have to set the weights correctly. But a more complete model (26 bodies, 29 coordinate...
