Here is the last of today's I Heart Engineering product releases, our button mounting system for the TurtleBot. This kit will enable your TurtleBot to interact with humans that are not carrying around their laptop in one hand while trying to type with the other. Includes everything you need to add button except the TurtleBot and an Arduino. It will include an Arduino shield and all of the wiring needed to connect the buttons. The e-stop is a push to disable, pull to enable type and could be used to generate a software e-stop or it could be used to mute the speakers.
