Rory Cellan-Jones and the Tech Tent team visit CES, the electronics industry's giant annual event in Las Vegas where manufacturers unveil the gadgets that will soon be in the shops. We meet a scarily realistic humanoid robot and check out a new Chinese-backed electric car. Plus we chat to China's search giant Baidu about facial recognition. With BBC tech reporters Chris Foxx, Zoe Kleinman, and Dave Lee, and special guest Ben Wood from CCS Insight.
