CMC positional inaccuracy
Hi all, Problem 1 : I have a hand model with measured small inertial properties (1E-7). I have a problem running CMC during finger flexion. it gives very large position errors. Multiplying the properties by 1000 solves the problem. Why so much positional inaccuracy is coming into picture while solvi...

Re: inertia properties problem with CMC
Hi Mojtaba I am also performing CMC of hand model. I have used the mass and inertial properties from research paper benjamin et.al (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5597339/) but since mass and inertial properties are smaller (10^-7 range) so I am also getting too much positional inaccur...

Wrist model_CMC simulation
Hi Everyone I have downloaded the Delp model of Wrist and have been trying to calculate the muscle forces using CMC in Wrist Model. Capture.JPG I have given mass and inertial properties from benjamin's research paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5597339/). In model I am giving motio...

Dynamic capable wrist model with all masses and intertia
I wanted to perform the Static Optimisation and CMC for the cylindrical grabbing case in wrist model made (curling fingers to hold an object). The model given in repository (wrist model by Delp, Gonzalez) is not dynamically capable as it misses mass and inertia of finger bones. Is there any dynamic ...

Re: CMC is not running in GUI
Hi, I have tried CMC with giving residual actuator file also, but it is getting struck at the same time (optimisation is not getting started). Note: No error message is coming, just getting struck same as earlier. Is there any dynamically capable model available of hand including all fingers in whic...

Table Reporter for Inverse Dynamics in MATLAB
Hi Everyone I was performing Inverse Dynamics simulation to calculate the joint torque required for a trajectory in MATLAB. I have run the Inverse Dynamics Simulation using MATLAB but i not able to export the data to tablereporter. Can someone tell me how to use reporter. code I am using for running...

CMC is not running in GUI
Hello All I was trying to run the CMC tool on hand model to calculate the metabolic cost and muscle forces. I dont want to apply any external forces and I am not providing any residual actuator file (is it necessary ??) but optimisation process is not getting started at even t=0, I have attached the...

Mass of actuators
Hey,
I was trying to mount a actuator on one finger and simulate, but i am not getting how to include the mass and inertial properties of actuators in the model ?
