- Location: The Marine Autonomy Lab, MIT Sailing Pavilion
- Competition Type: 1 robot and 1 human per team

Tips for Downloading the Data
- Using a web browser to download a large tar file should work fine if you have a high-bandwidth internet connection that doesn't get interrupted.
- For other cases you might consider a command line tool. In particular a tool that (1) works over the http or https interface, unlike rsync which does not, and (2) can resume where it left off, should it get interrupted, like rsync. To check out such a tool see this page, which describes how you can use the free tool, curl, along with a wrapper to keep re-starting if your download is repeatedly interrupted.
Unpacking the Data
The first step after successfully downloading the tar file is to unpack (untar) the file. Using Competition 2018_08_10_C051 as an example:
$ tar xvf 2018_08_10_C051.tar
This should produce a folder looking something like:
2018_08_10_C051/ RECAP_VIDEO_C051.mov README mokai/ red_one/ red_two blue_one blue_two heron/ red_three/ red_four blue_three blue_four shoreside/
Inside each of the primary eight folders, one for each robot and human platform, resides the data. A recap video, like the one shown on the web page is included in the RECAP_VIDEO.mov file.
