Great question. That is possible, and we already use this trick for the flexion/extension rhythm. Here the coefficients change between between two sets of coefficients. A sort of bi-linear rhythm. One set of coefficients for flexion and others for extension, with a smooth transition between these. It works using an interpolation function. For the bi-linear flexion/extension rhythm the interpolation function built from two straight lines with different slopes. One for positive and one for negative inputs. The bi-linear rhythm is easy enough to uses, but the underlying AnyScript implementation is bit more convoluted. It seems I can't post links here, but if you ask the same question on the AnyScript community forum, then I may be able to give you some more help on how to do this.

Hi, there has actually been some work along those lines. I believe you will find this webcast interesting: ua-cam.com/video/c3DtQGWaFnA/v-deo.html (Musculoskeletal modeling for the evolutionary biologist: A primer) or this recent publication: Sylvester A, Kramer P, (2024), "Achieving kinematic identity across shape diversity in musculoskeletal modeling".

Sorry for the late reply. There should not be any issues with registration - i just completed the process. If you are still not able to register, please use our contact form to get in touch.

Hi, If you applied for the trial license through our website you should receive a reply within a few days. Please see the information here: www.anybodytech.com/resources/trial-license/ Best regards, Kristoffer

Hi, Yes, we have implemented a novel version of RULA in the AnyBody Modeling System. Please contact us through our contact form (www.anybodytech.com/contact/) to request access. Best regards, Kristoffer

Hi Beatriz, Sorry for the slow reply. I am not sure which files you are referring to specifically, but i would recommend having a look at the presentation file (www.anybodytech.com/webcasts/musculoskeletal-modelling-from-scratch-concepts-made-easy) or go directly to our AnyBody tutorials: anyscript.org/tutorials/

Hi Vivaindran, I am not sure i understand you question correctly, but if you are looking for how the system is used in Orthopedics i would recommen having a look at our publication list (filtered by the keyword orthopedics): www.anybodytech.com/resources/anybodypublications/?selected=orthopedics

Hi Zeinab, Unfortunately the AnyScript file for the exoskeleton is not publicly available

The AnyBody Modeling System

@@anybodytech thx

Thank you for your comment. If interested, we do have options to get a trial license through our website.

@@anybodytech I saw it yes! I'll use it once I'll be a worker! 😁

Hi must pato, I think the best option is to use the contact form on Innophys official website. Best regards, Kristoffer

Hi Christine. You are welcome to download the model files and take a look. You can't import them to OpenSim, unfortunately. So you would need the AnyBody Modeling System to use them. You can however use the underlying MoCap dataset (c3d files) which University of Leeds are releasing in coming year. See this link doi.org/10.5518/345 . But you would have to construct a model your self in OpenSim.

Hi Muhammad, We're glad that you found the webcast useful! We haven’t registered your trial request, and so I’d request you to apply again over here www.anybodytech.com/contact/inquiryfolder/trial-inquiry/. You could alternatively email the information requested in the form to sales@anybodytech.com. Question 1: You are partially correct here :) If your model has 44 DOFs, you must specify motion trajectories/constraints for all 44 DOFs using driver objects (Note that one driver can apply multiple constraints) in your script. But these 44 DOFs need not be the joint angles, and you can choose which measures constitute these DOFs. Example, Constraining 6 DOF between each foot and the ground instead of leg angles. In AnyBody, we make this task easy for you by providing a “BodyModelWithDefaultDrivers” (see video at 31:00) which is a body model that comes with 44 default Soft drivers. There are two thumb rules to remember: (1) Number of Hard drivers + Soft drivers >= Number of DOFs, (2) Number of Hard drivers <= Number of DOFs The 44 default drivers automatically satisfy thumb rule 1. Thus you can manually add up to 44 hard constraints or any number of soft constraints (Based on thumb rule 2) to over-ride the default soft drivers if necessary. So you only need add those drivers which you really really need! Question 2: If you tried this motion in real-life there will always be some relative motion between the hand and crank. For example, the crank will twist inside your fist as you complete a revolution. The soft drivers thus allow some relative motion while simultaneously trying to minimize any such movement. I would thus expect the simulation to fail if you changed the drivers to hard. I am not sure of what you meant by an issue at the elbow, but it is quite possible that this isn’t the ideal motion! Motion prediction is a useful tool, but at the same time will need some amount of tuning to exactly mimic a real-life motion. It is possible that I may have missed something out in this example. :) Regards, Ananth

Thanks Ananth for such explanation. Yes, I have applied for the trial vsrsion and I am eagerly waiting for the approval (trial license file) so I can get started with it. Thank you, Muhammad

Dear Ananth, Thank you so much for the explanation. It really cleared my confusion about why you used soft-drivers. About the trail license request, I have already sent a request (by filling the trial request form) as well as dropped an email to the sales' team. I hope that I soon get the reply from them so I can get started. Thank you again, Muhammad Arshad

Hi Rizwan. Sorry we missed your comment here. The feature you were requesting wasn't available in this version (6.1). But version 7.0 which was just released does support this. We will make webcast demonstrating version 7.0 available middle of next week.
