America wants to wean itself off Chinese technology. Will the pain pay off?

Seven years after founding a robotics startup in San Francisco, Rajat Bhageria is confronting a daunting new task: building robots without any help from China. Like most US-based robotics firms, Chef Robotics has come to rely heavily on Chinese components to make the robot arms it sells to food manufacturers to automate the assembly of ready-made meals. China’s ability to churn out cheap parts at incomparable volumes has made it an integral source of competitive tech products around the world. But as China has begun to dominate advanced industries from electric vehicles to automated factories, an increasingly protectionist US under President Donald Trump has ratcheted up restrictions on domestic use of Chinese technology, including drones, mobile robots and other critical electronics. “For a while of course, it was like, ‘Hey, let’s find the best components, and let’s find them at the cheapest price,’” Bhageria said.
