Smartphone with robotic camera arm demoed by China's Honor, seen 'nodding' to user commands

China's Honor has demoed its Robot Phone at the Mobile World Congress in Barcelona. The device's camera, which is placed on a robotic arm that pops out of the smartphone's main body, can lock onto an object or person to track it as it moves. A video showed the robotic camera, which can 'dance' to music, 'nodding' to user commands.
