On May 25, 2018, the OpenSim team is conducting an interactive tutorial through the features of OpenSim that allow you to model and simulate human-robot interaction. The OpenSim software package has become a central tool in studying human movement and pathology. As interest in wearable robotics increases, so does the need for simulation tools to understand and predict the interaction between humans and robots. This 3-hour hands-on Matlab tutorial includes building your own model from scratch, simulating a jumper model, increasing jump height with an assistive device, and maximizing the jump height of the assisted jumper model through a competition and with numerical optimization.
The workshop does not assume experience with OpenSim, but participants should be familiar with Matlab.
Preparing for the workshop
We will conduct the workshop using a beta version of OpenSim 4.0 libraries (the GUI is not included). To ensure the workshop starts smoothly, please set up and test this beta version before the workshop. We will allocate only 5 minutes during the workshop for set up; if you do not have OpenSim set up after this time, we'll ask you to pair up with someone.
- Windows 10 (64-bit) or Mac (macOS 10.10 or later)
- Matlab 2014b or later (64-bit)
- optional: Optimization Toolbox and/or Matlab Global Optimization Toolbox.
- Download the OpenSim beta software and workshop files:
- Unzip the files to a location of your choice; perhaps C:\opensim-core-dw2018 (on Windows).
- If you use Windows, edit your PATH environment variable to include OpenSim’s bin directory (e.g., C:\opensim-core-dw2018\bin). See here for instructions. Make sure to remove any previous OpenSim installations from your PATH (alternatively, rename the folder containing the previous OpenSim installation).
- Configure OpenSim with Matlab by starting Matlab and running configureOpenSim.m, located in Resources/CodeExamples/Matlab/.
- After the script completes, restart Matlab and test the configuration by checking the timestamp from running
You should see an empty visualizer window.
