Theory and Publications
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...

coordinate system of the sensors
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...

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

Re: If OpenSim suitable for IMU motion capture enhancement?
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...

Data transfer with inertial sensor system
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...

Negative Mass after RRA
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 (...

Help required in the given tutorials
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...
