From one of the Forbes articles referenced earlier:
Continuing with the theme of inference processing in China, NVIDIA also announced that the JD.com delivery subsidiary would be using the NVIDIA Jetson platform to guide and control its land and air drone delivery services. Delivering products through China’s crowded highway infrastructure is unreliable and time-consuming. To address this growing challenge, JD.com plans to have a million drones, with NVIDIA Jetson on board, in service by 2020.
That’s a lot of Jetson chips!
