Looking sharp and professional in a black vest and bow tie, a humanoid robot showed up for its first day of work at a new job Monday selling coffee machines for food giant Nestle Japan Ltd.

"By simply answering my questions, I can tell which coffee machine is perfect for you," Pepper declared with confidence during the opening rituals at Bic Camera's Yurakucho store in Tokyo.

In its new role, Pepper will greet customers at electronics shops and show off its sales skills. It can explain the difference between the Nestle Dolce Gusto and Nestle Gold Blend Barista coffee machines and help buyers choose the one suitable for their needs.
