All of X9's core software for the 2016-2017 Purdue ROV team.


scotty is our favorite cheif engineer that install the dependencies, runs the software, and runs tests.


sudo ./scotty install # do once, or when dependencies have updated
sudo ./scotty run

Using Scotty to Install Dependencies:

scotty install [--pi] [--dev [--cam]]
   Installs required files. Autodetects install type
   --pi:     Install as if this is a Pi
   --dev:    Install as if this is a dev machine
   --cam:    Also install mjpg streamer for dev

sudo ./scotty install will auto detect if you're on a Raspberry Pi or not, and install all the needed items. This includes:

  • pip
  • install/requirements.txt and install/requirements-hw.txt
  • mjpg-streamer
  • configure I2C

If you aren't on a Raspberry Pi, it will not install the hardware items or mjpg streamer. If auto detect fails, you can pass in --pi or --dev. If you're installing on dev machine and want mjpg streamer, pass in --cam.

Installs should be idempotent, which means you can rerun them with no adverse effects. If requirements ever get updated, just rerun the install.

Note: sudo is needed, because some dependencies need to be installed via apt-get

Running the App:

scotty run [--rov] [--debug]
   Runs the full ROV stack
   --rov:    Just test the ROV main loop
   --debug:  Set FLASK_DEBUG and ROV_DEBUG

If you want to run the full ROV program, run ./scotty run. This starts the flask application. If you want to just test the ROV main loop, run ./scotty run --rov. This starts the rov for tests, without the flask app. Passing in --debug sets the environmental variables configured in environment.debug in install/config.json. By default, it will set the FLASK_DEBUG to true, as well as ROV_DEBUG, which can be used to optionally turn things on and off in debug:

if os.environ['ROV_DEBUG']
    print "This only prints with --debug!"


scotty shell [--debug]
   Runs a new shell, with the activated venv. Exit to leave venv
   --debug:  Set FLASK_DEBUG and ROV_DEBUG

./scotty shell will start a new version of your current shell, with the appropriate environmental variables set. This lets you run flask run, and mjpg_streamer, as they will be added to your paths. The virtualenv is also added to your path, so dependencies will be installed there. If you pass in --debug, the environment.debug variables in install/config.json will be set as well.


scotty test [files...] [--pep8] [--pylint]
   Runs the full testing framework
   files:    optional list of files to test
   --pep8:   Run pep8 test
   --pylint: Run pylint test

Scotty will run linting tests to check for things like unused variables, bad imports, bad spacing, etc. Think of it like a compiler. This helps to catch errors that will not show up until runtime. Right now there are two tests:

  • pep8: tests against pep8 style guide
  • pylint: tests for undeclared variables, bad whitespace, misspelled items

Will hope to add more tests that can test our modules individually

You can’t perform that action at this time.
