This Repo is for the MICS ~~2014~~ 2015 Robotics compitition

This year our team tried to use an arduino with the NXShield created by OpenElectionics. A user guide can be found here: http://www.openelectrons.com/index.php?module=documents&JAS_DocumentManager_op=viewDocument&JAS_Document_id=1, as well as an advanced guide and a tutorial. The user guide contains a lot of useful links, but the key ones can be found below.

Pin Mappings and Hardware Configuration

Much knowledge about pin mappings has been lost due to people not pushing to github, but it shouldn't be too hard to figure it all out again.

Dianostics Mode

The robot has a basic diagnostics and troubleshooting mode which constantly prints out all sensor values to the LCD, as well as allowing manual control of the chain motors.

To enter diagnostics mode, power on the robot. Upon seeing the voltage readout message, or a message instructing you to press go, hold the "Right arrow" button on the shield. While holding the right arrow button, press the "go" button. Release both buttons.

To exit diagnostics mode, reset the arduino or power cycle the whole bot.
