So you did no research on already deployed robots including multiple versions of the following: the Talon, Dragon Runner, and iRobot Packbot just to name the big 3. Over 6,000 of these units have already been deployed for years with combat engineers and EOD. Those units also include remote firesets and shotgunPAN disruptor options. Most of them run off of various open architectures including JAUS and MOCU among others.
This is literally just the latest round of these types of robotic systems. The quip about Skynet is juvenile and outdated.
