The objective of this example is to adjust the eccentricity of the cable wheel such that the arm muscles experience a constant effort throughout the elbow flexion taking the change of moment arms of the muscles into account.

It is not possible to obtain a completely constant muscle effort with only the eccentricity as parameter. However, if more parameters were introduced into an actual design optimization, then it is likely that an almost completely uniform effort profile could be obtained.

By chaning between the files “EnvironmentOptimized.any” and “Environment.any” it is possible to to see the machine with adjusted eccentricity and the one with zero eccentricity
