Hi ? Sorry about you problem, as you write this is not supposed to happen… I am not sure what you mean when you write “When I directly added this stl files...
Hi Sungwoo Yes this is possible. If you have a model with measured forces applied at boot feet, you can run the model with no muscles and read out the moments...
Hi Soren, I am getting this warning after adding ligaments in the model. Do you have any guess about what might be wrong? Or I should upload the model? Thanks ...
Hi Prabhav It rings a bell... I think it might be because you have defined L0 as an expression of some other variables, for example: L0=Lt*0.9; The calibration...
Hello guys My name is Shivaswamy Anirudh. I am an MS student at SUNY Buffalo, working under Dr. Venkat Krovi. I am working on a leg model which we modified...
Hi Shivaswamy, As you can see in the code JointPos is pointing at the folder Mannequin.Posture : AnyFolder &JointPos=..Mannequin.Posture; This folder is...
Hi Prabhav After having tested it a bit further I am afraid that what you have troubles with, is a bug in AnyBody. Fortunately it looks like it is rather easy...
Hello My name is Shivaswamy Anirudh. We are trying to do the analysis of the knee joint. While doing inverse dynamic analysis, it says "kinetically ...
Hi Shivaswamy, The model being kinetically over-constrained means that there are too much reaction forces. In your case the Reaction.Type of the hip joint and...
Dear Soren: I have a simple question about the reference axis in universal or spherical joints. For example, the joint is defined as: AnyUniversalJoint MCP = {...
Hi, all I have another question this time. I defined ankle joint as a universal joint with x and z axis. And I want to input joint angles and time to generate...
Hi I'm a user I had such a problem in shoulder. Finally I eliminated drivers on my joint and apllied motion profile data from a txt file on the node which...
Hi, To apply an AnyKinEqInterPolDriver to a universal joint the Data member must contain 2 vectors as there are 2 degrees of freedom in the joint. The correct...
Dear John These axes are defined in the first mentioned reference frame of the joint, so in this case it will be the Body_A reference. Best regards Søren,...
Hello, I am attempting to create a musculoskeletal model of the hip joint, involving only the femur and the pelvis from custom built bone models. I have...
Hi, My name is Arif Oyong, I am doing research on the use of robot for stroke rehabilitation. One of the thing that I am doing now is the implication of robot...
Hi Bonn Sorry about your download problems Some more details are needed to be able to solve the problem: Which browser and operative system are you using?...
Hi Arif, First let me be sure i understand correctly how is working the device: I suppose the base of the robot (purple part) is fixed to the ground, then the ...
Hi Prabhav After some further checking it appears that the error message does not have any influence on the results, it works ok, no matter the error message....
Dear Sylvain, Yes, you are correct, at this point I am using the robot to drive only the 3 glenohumeral joints and elbow flextion. With the above mentioned...
Hi, The problem comes from the dummy segments supporting the cylinders that you created for the wrapping. The Reaction.Type of those segment's drivers are all...
Hi, all I really appreciate with your solution about applying angle data for universal joint and ground reaction force data last time. It worked!! I'm making...
Hi Arif, The spherical joint alone between the hand and the robot is not enough to drive the 4 arm's dof you want. You clearly need a 4 constraints joint on ...
Thanks, I revised the model and figured out the problem; however, I added an instance of AnyForceMomentMeasure to measure the moments generated on the knees,...
Hi Sungwoo, I can't test your model in inverse dynamic analysis because the text file for the ground reaction force "high_1_force.TXT" is missing. Would you ...
