OpenSim questions from newcomers
Posted: Tue Feb 20, 2018 12:30 am
Currently my team's biggest focus right now is being able to make custom models through OpenSim.
(1) We were curious if you guys had any examples on a human model simply sitting and standing from a chair.
(2) We also have another simulation where we're focused on making a model of two intersecting hollow cubes that fall together and connected with "custom muscles"/ elastic elements. We've had issues making our own custom muscles to accurately resemble what was calculated.
(3) We were curious if there's an easy way to implement this hollow cube through an stl file and recognize if there's an edge without making a ton of contact sphere elements on corners. If there's an explanation/ink on the options for different ContactGeometry elements besides "ContactSphere" or "ContactHalfSpace", that would be great!
(4) If there's some tips & tricks related to making ground reaction elements/models stable (i.e. finding correct values for stiffness, dissipation, static_friction, etc.), and able to freely translate as across the platform. Currently our model bounces rapidly out of control and does not just stick the landing as we hope so we could proceed with making the model traverse across an inclined platform.
(5) Less pressing, but we also were struggling to get the OpenSim working with C++. We've been extremely successful building custom models through XML, but stumped on how to model via C++ flies.
