Housekeeping

1. Please organize your files into your sections: comms, software, hardware
2. Commit your work to the dev branch and submit PRs to master after your counterpart has reviewed.

Moves

• Chicken
• Cowboy
• Crab
• Doublepump
• Hunchback
• Jamesbond
• Mermaid
• Raffles
• Runningman
• Snake
• Stationary (default move that is not recognized by the server)
• Ultimate

The "Ultimate" move is simply a vertical, oscillating movement of the left hand above the head, with the right hand (palm-facing up) at the abdomen as though the dancer had stabbed themself.

Communication Protocol

Communication protocol is JZON1.2. Packets follow the following convention:

[57][PACKET_CODE][LEN][DATA]

and are responded to with either an ACK, NACK, or RESET.

Data Collection and Training

When collecting data for the ML model we simply run a test file (which dumps output data to console in pseudo-JSON) adapted to save the output to a .out file.

Assuming test is an alias of python3 test_comms.py,

test >&1 | tee ../data/transient/<username>_<movename>.out

After collection simply convert the outfile to JSON by replacing ' with ", adding commas to the end of each line, and adding [] to encapsulate the contents of the file. Finally, rename the extension from .out to .json. Melvin will use this for his training model.

Connecting To Server

Once you are ready to kickoff the dancing, enter python3 RPi.py <server_address> <server_port> <level_of_difficulty>, where level_of_difficulty is a float number between 1 and 3, where 1 is the hardest. This command is entered in the terminal window of the RPi.

Please wait for the connection to the server to be established before proceeding. The program will prompt you to hit ENTER. Only do so when the server has displayed the first move. Otherwise data will start being sent to the unprepared server.

When you have danced the logout move, the server will detect this and automatically exit. Following which, the terminal program would end with a Broken pipe error. Nothing to fear, simply hit CTRL+C to quit.
