Robots were popular on the big screen this holiday season. The newly released film Star Wars: The Force Awakens brought us more of C-3PO, R2-D2 — those sweet and capable robots that have enchanted us for decades — and the debut of BB-8.
At this year's big consumer electronics show in Las Vegas, known as CES, there were more robots on display than ever. Some even looked like the Star Wars characters.
The most promising by appearance was Pepper. It has humanoid features — eyes, arms, a mouth. Pepper can even be a little self-conscious.
