New E-Stop

Designed a new E-stop board based on Chad Rockey’s design for Otto. Like his design, it uses a xBee radio. Unlike his design, it will have user feedback on the remote and will be able to work with all of the other E-Stops on the robot (including the IRC5).

Features

• Can disable the IRC5 if the rest of the robot is E-stopped
• Will E-stop the whole robot if the IRC5 is E-stopped
• Will E-stop if the remote E-stop is triggered
• Will E-stop if it loses contact with the remote controller
• Will E-stop if the cRIO commands an E-stop
• Provides feedback to the user (probably via LEDs) on the remote as to the status of each E-stop on the robot.
• Entirely hardware implementation (no microprocessor, no software)

I still haven’t designed the remote itself, and the e-stop board needs some revision, but the first revision is done.
