Look out, Pepper: you have some fresh competition. Hitachi has unveiled EMIEW3, its first humanoid assistant robot built for full-fledged commercial service. Like its SoftBank-made counterpart, it's designed to help you find your way around stores and public facilities. It's particularly focused on tourists, as it can switch languages on the fly. However, its edge may simply be its ability to cope with real-world situations. It's much faster than Pepper (3.7MPH versus 1.2MPH), so it's more likely to keep up with humans; it can also get back up if it falls down, and listen to you in noisy street environments.
