We hope you will be able to set up your environment properly before you arrive, but we'll be glad to help you with these steps during the workshop.
Post Workshop Update
With many people having trouble setting up their Matlab environment, we are release two model files to this page which can be used to complete the walking challenge. These files are:
- DW2013_WalkerModelTerrainAddMagnet.osim - This file uses ExpressionBasedPointToPointForces to realize a magnet attractor between two points in global space.
- DW2013_WalkerModelTerrainAddCustomFeet.osim - This file adds ContactMesh geometry to visualize a cylinderical foot with a large radius of curvature.
Both models have editable properties that can be accessed in the OpenSim GUI properties panel. For the magnet model, consider changing the location of the points and the expression of the curve to tune your magnet extension moment. For the custom feet model, consider changing the location of the foot relative to the shank by editing the weld joint description in the navigator pane.
Share your Scripts
If, during the workshop or afterwards, you develop any models or Matlab scripts that you'd like to share with other workshop participants, email them to Chris Dembia and we'll post them right here. Please include DWC2013in the subject line, and be sure to credit yourself inside the files you send.
