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 create a magnet attractor between two points in global space.a point on the thigh and a point on the shank
- DW2013_WalkerModelTerrainAddCustomFeet.osim - This file adds ContactMesh geometry to visualize for a cylinderical cylindrical foot with a large radius of curvature . to be used in an elastic foundation model of contact.
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.
