Hello all. The last few months I had to stop my practical work for writing some reports and documentation. The first part in my documentation was, to introduce IMUs in general, then the ones I use, the mathematic of quaternions and so on and so on. the next thing i would like to do, is to show how m...

hello all, i have my data from my IMUs converted so far. i am trying to find the correect coordinate system. but the movement goes always in the wrong direction, no matter how i transfer my coordinate system. i really have tried every possibility. i would be very thankful, if you could tell me, whic...

hallo all,
could anyone please tell me where to find the coordinate systems of femur, tibia and calcn.
best regards
hajo

hello all.
I have taken a screenshot of the problem.
It would be great if someone could tell me what ia am doing wrong. i am not a matlab pro at all...
thanks for your help

Hi James and Yuri. I think i am just working on a very similar project. i am trying to simulate gait by an IMU sensor System and measure the GRFs with a preasure walk way. a former project simulated a knee bend with IMUs but with the help of a kinect camera (IR). My task would now be to do this just...

Thank you.

hello all. I am still training to handle OpenSim as part of my practical semester. My task is to create a new model, but not with motion capture rather with an inertial sensor system (shimmer sensors). These Data I want to transfer with MatLab into OpenSim. So, does anyone have experinces in working...

Hello. I was just beginning to think that i understood waht i am doing and why... BUT... the intermediate example "The Strength of Simulation: Estimating Leg Muscle Forces in Stance and Swing, Part II: Leg Muscle Force Estimation in Stance" is not doing what i want it to do. One of the exerises is (...

Hello. My name is hajo and i am a mechanical engineering student from Dortmund/Germany and i want to write my bachelor thesis about OpenSim. I am the only one who is working with this software. It is rather difficult for me, that there is no one to discuss about problems and so on. I would be very t...
