Hmm seems like Google Docs in general is giving a lot of issues, so I'll post it here.
Unfortunately, you can’t run code on Chromebooks; however, there should be a designated Windows laptop in the room that can run all the cool stuff you made.
Make sure that everything you need (Python 2.7, PySerial, and the MMM library) is installed. Everything you need to know is here: http://www.choitek.com/python-27.html
To start off, I would recommend running the Robot Motion Test found here: http://www.choitek.com/examples.html. Follow the directions as follows, and if everything goes well, try out more files!
In the file you want to run, make sure you have the correct COM port. To check which COM port you have, plug in the USB to the laptop, open up Arduino, then click on Tools. Click on Port to see which one you have.
Type the correct COM port into your file. For example, I have COM5, but you may have something different.
On the Windows laptop, save the file you want to run to the computer (not to Google Drive). Save it in the same location as your MMM Python files. See example below. The file I wrote (target.py), is in the same spot as MMM.py.
Now, open up Command Prompt, or Terminal (Start -> Command Prompt).
Navigate to the folder which contains your code:
To go back to a parent directory, type: cd ../
Once in the folder, type:
Plug the USB into the laptop. Make sure the robot’s arms and bottom wheels are on. Make sure you have Arduino open.
Then, click enter. If there are any bugs, a message should pop up saying what’s wrong. If all goes well, the robot should start moving, and doing a little motion test!
Now try it out with the files you would like to test! Have fun!
