Introduction: A New Front in the Battle for Connected Device Security
As smart devices become increasingly embedded in homes, businesses, factories, and national infrastructure, governments are paying closer attention to the hidden risks inside connected technology. The US Federal Communications Commission (FCC) has taken another major step in this direction by adding foreign-produced mobile robots and network-connected power inverters to its national security-focused Covered List.
The decision represents a broader shift in cybersecurity strategy: instead of waiting for attacks to happen, regulators are increasingly attempting to limit potential supply-chain risks before vulnerable technologies become deeply integrated into critical environments.
The FCC action does not immediately ban every existing foreign-made robot or inverter in the United States. Instead, it restricts future equipment authorization for certain categories of devices that meet specific technical and production criteria. Existing approved products can continue operating, receiving certain security updates, and remaining in use.
However, the move highlights growing concerns about remote access capabilities, artificial intelligence systems, wireless communications, and the possibility that connected infrastructure could become a target during geopolitical conflicts.
FCC Adds Mobile Robots and Networked Inverters to Covered List
A Preventive Cybersecurity Move Against Potential Supply-Chain Risks
On July 28, the Federal Communications Commission expanded its Covered List to include foreign-produced mobile robots and connected power inverters. Devices placed on this list generally cannot receive new FCC equipment authorization, meaning manufacturers may face restrictions when attempting to import, market, or sell new models in the United States.
The FCC explained that the action is based on national security concerns rather than a blanket restriction against specific brands or countries. The decision focuses on whether products meet defined technical requirements and whether they qualify as foreign-produced under federal procurement standards.
The goal is to prevent potentially risky technologies from becoming widely deployed before security problems emerge.
Existing Devices Are Not Immediately Banned
Current Owners and Previously Approved Products Remain Protected
A major point of clarification is that the FCC action does not disable devices already operating in the United States.
Previously authorized robots and power inverters can continue to be sold, used, and maintained. Federal agencies are also not automatically prohibited from owning or operating existing equipment because of this announcement.
Manufacturers may continue providing qualifying security patches and compatibility updates for approved hardware. The FCC created a temporary pathway allowing certain software and firmware updates until at least January 1, 2029.
This exception recognizes an important cybersecurity reality: blocking security updates could create even greater risks by leaving existing devices vulnerable.
New Conditional Approval Process Created for Manufacturers
Government Agencies Will Review Exceptions
The FCC has introduced a conditional approval process for manufacturers that want certain devices reviewed despite the new restrictions.
Applications must be submitted before January 1, 2028.
According to the new framework:
The Department of War (DoW) may approve robotic devices.
The Department of War or Department of Homeland Security (DHS) may approve power inverters.
This approach allows government agencies to evaluate individual cases where technology may be considered necessary but requires additional security review.
What Counts as a Covered Mobile Robot?
The Definition Goes Beyond Humanoid Machines
The FCC’s robot category is broader than many people may initially assume. It does not only target humanoid robots but includes various autonomous or semi-autonomous mobile machines.
A covered robot must generally:
Be capable of moving on the ground.
Navigate or avoid obstacles.
Operate remotely using commands or sensor information.
Weigh more than 4.4 pounds, including docking equipment.
Include environmental sensors.
Support wired or wireless communication of at least 200 kbps.
Run software that controls movement, perception, data collection, or remote operation.
The software requirement also includes artificial intelligence models, machine-learning weights, and firmware.
This means the FCC is not only concerned about the physical machine but also the digital intelligence controlling it.
AI-Powered Robots Become a New Security Battlefield
Remote Intelligence Creates New Attack Opportunities
Modern robots increasingly rely on artificial intelligence, cloud connectivity, cameras, microphones, and sensor networks.
These capabilities create powerful functionality but also introduce security challenges.
A compromised robot could potentially become:
A surveillance platform.
A data collection tool.
A gateway into corporate networks.
A device for physical disruption.
A remotely controlled machine during a cyber conflict.
The FCC referenced multiple security studies supporting its decision.
One report described research showing that attackers could access camera feeds, microphone recordings, and building maps from thousands of household robots.
Security Researchers Previously Demonstrated Robot Vulnerabilities
Unitree Robot Research Influenced FCC Concerns
The FCC cited several cybersecurity investigations involving robotic platforms.
One example involved UniPwn research, which identified multiple Bluetooth Low Energy vulnerabilities, including CVE-2025-35027.
Researchers demonstrated that exploitation could provide root-level command execution on several robotic systems, including:
Unitree Go2
Unitree B2
Unitree G1
Unitree H1
The research also showed that attacks could potentially spread between nearby devices through Bluetooth Low Energy connections.
Another vulnerability, CVE-2025-2894, involved Unitree Go1 quadruped robots connected through the CloudSail service. Attackers possessing the necessary API credentials could gain remote control capabilities.
These examples demonstrate how connected robotics can become cybersecurity targets.
FCC Excludes Several Categories of Machines
Not Every Robot Is Automatically Covered
The FCC determination contains several exceptions.
The covered category does not include:
Connected road vehicles.
Rail-only equipment.
Uncrewed aircraft.
Unmanned underwater vehicles.
FDA-regulated medical devices.
Mobility assistance devices.
Fixed industrial robot arms such as SCARA, gantry, and delta systems.
However, mobile devices outside these categories may still fall under restrictions if they meet the FCC’s technical requirements.
Connected Power Inverters Become a Critical Infrastructure Concern
Renewable Energy Technology Faces New Security Scrutiny
The FCC also added network-connected power inverters to the Covered List.
Power inverters are essential components in solar systems, battery storage installations, and energy networks because they convert direct current electricity into alternating current and sometimes perform the reverse operation.
Modern smart inverters often include:
Remote monitoring.
Cloud connectivity.
Data collection.
Remote control features.
Software update systems.
The FCC warned that compromised inverters could potentially be abused to disrupt energy operations or gather sensitive information.
Cybersecurity Researchers Warn About Grid Manipulation Risks
Smart Energy Systems Could Become High-Value Targets
The FCC referenced research from Forescout called SUN:DOWN, which identified dozens of vulnerabilities across inverter products from manufacturers including Sungrow, SMA, and Growatt.
The research discussed risks involving:
Unauthorized control.
Fleet-wide manipulation.
Potential instability in energy systems.
However, the FCC emphasized that these findings did not represent evidence of an active attack causing real-world grid disruption.
The concern is based on possible future abuse, particularly because energy infrastructure is increasingly connected and remotely managed.
Remote Shutdown Capabilities Raise National Security Questions
The Risk of Foreign-Controlled Infrastructure
The FCC cited concerns that remote access to power inverters could allow attackers to:
Shut down systems.
Extract operational data.
Conduct surveillance.
Support broader cyberattacks against critical infrastructure.
The agency referenced research from Idaho National Laboratory and warnings from energy organizations about the potential consequences of large-scale manipulation.
One cited incident involved a foreign manufacturer remotely disabling inverters after a commercial dispute with a US distributor.
The company involved was not identified.
A Growing Pattern of Technology Restrictions
The Third Major Covered List Expansion
The FCC’s latest decision follows previous category-wide actions targeting foreign-produced technologies.
Earlier additions included:
Foreign-produced drones in December 2025.
Consumer routers in March 2026.
Together, these actions show a growing regulatory focus on devices that combine physical hardware with internet connectivity.
The government’s concern is increasingly centered on technologies that can collect data, communicate remotely, or influence important systems.
Deep Analysis: Understanding the Strategic Impact of the FCC Decision
Cybersecurity Is Moving From Detection to Prevention
The FCC action reflects a major change in cybersecurity thinking. Historically, governments often responded after vulnerabilities were discovered or exploited. Today, regulators are increasingly attempting to prevent risky technologies from becoming deeply embedded before problems occur.
This approach treats supply chains as part of national security.
A vulnerable device does not need to be actively exploited today to create concern. If millions of connected devices are deployed, a future vulnerability could become a significant security problem.
Connected Hardware Creates Invisible Attack Surfaces
Robots and smart inverters represent a new generation of cyber-physical systems.
Unlike traditional computers, these devices can interact with the physical world.
A hacked laptop may expose data. A hacked robot could expose data while also moving, recording, or interacting with its environment.
A compromised inverter could affect energy operations.
This combination of digital access and physical impact makes these technologies strategically important.
Artificial Intelligence Increases Both Capability and Risk
AI-powered robots introduce additional complexity because their behavior depends on software models, training data, and remote updates.
Security researchers increasingly focus on AI supply-chain risks because malicious changes to models or software components could create unpredictable outcomes.
The FCC specifically included AI and machine-learning model weights in its definition, showing that regulators view AI components as part of the security equation.
Energy Infrastructure Is Becoming a Cybersecurity Priority
The global transition toward renewable energy has increased reliance on connected systems.
Solar farms, battery storage systems, and distributed energy networks depend heavily on software-controlled equipment.
This creates opportunities for efficiency but also creates new targets.
A single vulnerable device may not create immediate danger, but large-scale deployment could introduce systemic risks.
The FCC Approach May Influence Global Regulations
The United States is not alone in examining foreign technology risks.
Other governments are also reviewing supply chains involving:
Telecommunications equipment.
Artificial intelligence systems.
Renewable energy technology.
Autonomous machines.
The FCC’s decision may encourage similar regulatory frameworks internationally.
What Undercode Say:
The Rise of Cyber-Physical Security Threats
The FCC’s decision demonstrates that cybersecurity is no longer limited to computers, servers, and networks. The next generation of threats involves machines that move, sense, collect information, and control physical environments.
Supply Chains Are Becoming the New Security Battlefield
The agency is targeting potential risks before mass deployment. This signals a future where hardware origin, software ownership, and update mechanisms become critical parts of cybersecurity assessments.
AI Robotics Requires Stronger Security Standards
As robots become smarter and more autonomous, security testing must evolve. Vulnerabilities affecting cameras, microphones, navigation systems, and AI models could create serious privacy and safety risks.
Smart Energy Systems Need Zero-Trust Protection
Connected inverters should not be treated as simple electrical components. They are increasingly becoming network-connected computers controlling essential infrastructure.
Regulation Will Continue Expanding
The FCC’s previous actions against drones and routers indicate that more categories of connected devices could face similar scrutiny in the future.
