Applying Inverse Kinematics Using OpenSim

The developer will create a skeleton - type model using OpenSim, that will be able to calculate the parameters of the muscles that are activated during an elbow extension of the arm, based on the picture that we exchanged on chat, which shows that the arm is at the level of the eyes.
The developer wil have also to provide a demo video of the result and the file he will sent must produce the same result on my machine
