Introduction

The OpenSim team is running a workshop for the Dynamic Walking 2013 Annual meeting at Carnegie Mellon University, Pittsburgh, Pennsylvania. 

This workshop will cover the development and simulation of a passive dynamic walker in OpenSim.  Participants will be introduced to the OpenSim tools in both the standalone GUI and the new Matlab scripting tools.  The workshop will culminate in a challenge where the workshop participants will aim to maximize walking distance over increasingly challenging terrain.

This wiki pages directs the participants to all of the materials and instructions for the workshop.

Here is the tutorial that we will be going through during the workshop:Simulation-Based Design of a Dynamic Walker.

For this workshop, you must use version 3.1 (Beta) of the OpenSim software

Download the release beta from the OpenSim downloads page at simtk.org

Design Challenge

At the end of the workshop, we will have a small presentation of the walking model challenge entries. 

The challenge categories are:

Best Walking Gait

  • The model that moves the furthest through the obstacle course (based on pelvis location at touchdown of the leading leg at the last complete step) will be the winner.  If there is a relative tie, or if multiple models succesfully complete the course, the winner will be selected by audience vote. 
  • The model should be complete passive.
  • The model must not have a flight phase.  The sum of the contact forces will be checked (it's okay to have very short violations).

Best Innovation

  • The winner will be selected by audience vote.
  • There are no restrictions on the model.  (Add extra legs, muscles, whatever it takes to get down the course! Think outside the box!)
  • The model must spend a significant portion of the the time on the ground.

Best Blooper

  • Self-explanatory! The winner will be selected by audience vote.

To enter the contest, send an email to Chris Dembia with:

  • subject line "DW2013: <name-of-your-team>",
  • for each category you're entering:
    • your model file, named as "<name-of-your-team>_<category>.osim",
    • a link to a YouTube video showing your model in action (that is, upload a video to YouTube first).

The videos will be uploaded to the Workshop's Confluence page, where the other contestants can see and vote on them.
