The US is banning humanoids and other advanced robots made outside of the United States, the FCC announced, saying that "advanced robotics devices" pose a national security threat. Foreign-made power inverters have also been deemed a security risk. A press release from the FCC cited unnamed national security agencies. The agency uses similar reasoning in its ban on power inverters, which specifically covers devices that convert current and also have Wi-Fi, cellular or bluetooth connectivity. But, as with the ban on routers earlier this year, banning all foreign-made power inverters might prove to be difficult, at least in the short term.
