Push value (In robot loop)
self.s­d.p­ut­Num­ber­("Value name", value))

Viewing Network Tables
1) Install robotpy's eclipse plugins
2) Connect to the robot's router on your laptop

Python Robot Simulator

Use
BEFORE deploying code to the robot or pushing code to git make sure to test your code in the pyfrc simulator. This makes sure that your code will not crash the robot and can also be helpful when developing code at home away from the robot.

Running Simula­tor
1) Navigate 2016-­rob­ot/­robot/
2) Run the simulator with python3 robot.py sim

Deploy To Roborio

Depl­oying
1) Change your wifi to the robot's wifi 1418
2) Navigate to the 2016-­rob­ot/­robot/ directory in terminal.
3) Use command python3 robot.py deploy to start deploying.
4) Use the robot address robor­io-­141­8.l­ocal when prompted

Tests
If no tests are in the 2016-­rob­ot/­tests/ directory then your will have to deploy with --bui­ltin

Trou­ble­sho­oting
Update pyfrc: pip3 install --upgrade --user pyfrc
