Help with Standing Back Up After Single-Leg Landing in ToyDropLanding Model

[Haneyya Umer Siddiqui]

Hi, I'm working with the ToyDropLanding model in OpenSim. After landing on a single leg, my model starts falling off the platform instead of standing back up. I want it to regain balance and stand upright after landing.

What would be the best approach to achieve this? Should I adjust joint torques, use a controller, or modify foot placement? Any guidance or examples would be really helpful.

Just to be clear: I'm a HS student so I'm relatively new to OpenSim - I would love a breakdown of steps or even links to solution of this stability problem if possible.

Thanks!

Hi Haneyya,

There may be multiple directions you could go about this, which ultimately could be dictated by what questions you are trying to answer or what your research question is. In case you haven't gone through it yet, be sure to check out part V of the example: https://opensimconfluence.atlassian.net ... e+Injuries

For an example of simulating a model that is standing up, you can check out the exampleSquatToStand: https://opensimconfluence.atlassian.net ... t-to-stand
This is a different model setup, but might give you an idea of a potential direction for simulating standing up.

Hope this helps!
Jon
