PackBot is a series of military robots by Endeavor Robotics (previously by iRobot), an international robotics company founded in 2016, created from iRobot, that previously produced military robots since 1990. More than 2000 were used in Iraq and Afghanistan. They were also used to aid searching through the debris of the World Trade Center after &lt;a href="September%2011%20attacks"&gt;9/11&lt;/a&gt; in 2001. Another instance of the PackBot technology being implemented was to the damaged Fukushima nuclear plant after the 2011 Tōhoku earthquake and tsunami where they were the first to assess the site. As of November 2014, the U.S. Army is refurbishing 224 iRobot 510 robots. The PackBot technology is also used in collaboration with NASA for their rovers and probes.
