IMU Inverse Kinematics Tool

[Andrea Braschi]

Hi all,

I am trying to perform Inverse Kinematics using IMU data and the OpenSim (version 4.1) API with MATLAB.

As I run IK, here is the error that I get:

Java exception occurred:
java.lang.RuntimeException: AssemblySolver::assemble() Failed: SimTK Exception thrown at Assembler.cpp:227:
Error detected by Simbody method AssemblerSystem::objectiveFunc(): calcGoal() method of assembly condition
OrientationSensors returned a negative or non-finite value -nan(ind).
(Required condition 'goalValue >= 0' was not met.)

Any idea on what I should be looking at to fix this issue?

Many thanks in advance,

Andrea Braschi
