The Lidar Giant at the Center of a U.S. Security Debate

Hesai Technology, a Shanghai-based lidar manufacturer that counts Nvidia as a key partner, finds itself at the center of a growing controversy over national security and the future of autonomous systems. The company, which makes the sensors that allow self-driving cars, robotic dogs, and airport security systems to see their surroundings, was placed on a U.S. Defense Department blacklist in 2024 as a Chinese military entity. While the designation bars Hesai from Pentagon contracts, it doesn't stop American companies from buying and using its low-cost lidar technology - and many are.

Government officials and security experts argue that integrating Chinese-made lidar into U.S. infrastructure could open a backdoor for Beijing to access sensitive data. Craig Singleton of the Foundation for Defense of Democracies warns that the data collected by these sensors - precise three-dimensional maps of airports, utility grids, and city streets - could be weaponized by a hostile power. Hesai CEO David Li pushes back, saying the sensors lack memory capacity and cannot store or transmit data. He calls the security concerns a fiction, adding that Hesai publishes its firmware as open source and has passed independent safety audits from Tüv Rheinland and Dekra.

Still, critics point to a 2024 firmware glitch that caused all Hesai sensors to fail on Feb. 29 - a leap year oversight. Michael Robbins of the Association for Uncrewed Vehicle Systems International says the error shows what could happen if the bug were intentional. Meanwhile, lawmakers like Rep. John Moolenaar, who chairs the House Select Committee on the Chinese Communist Party, have proposed legislation to phase out Chinese lidar in the U.S. Hesai is appealing its blacklist status and continues to expand, with its sensors now used by Amazon's Zoox, autonomous trucking firms Waabi and Kodiak, and even New York's JFK Airport. The company has cut the cost of a lidar unit from over $10,000 to under $200, a price advantage analysts say is reshaping the global market.
