The Robotics Revolution has arrived … and one $7 stock could take off as a result. (Ad)

Something big is brewing in Washington. According to my research, an executive order from President Trump could be just weeks away. And it holds the potential to trigger one of the most explosive tech booms in US history. At the center of it all? Robots. Not the kind that clean your house or pour you coffee. But the kind that could reshape entire industries, add $1.2 trillion per year to the US economy, and affect 65 million American lives — just in the next year.
