Our Robots, Our Selves

If companion robots that are already popular in Japan are to make it big in the US and other countries, analytics will play a role in adapting their personalities for the likes and dislikes of other cultures.

Advancements in robotics are not just about developing better robots to do work on their own. It’s about developing robots whose work is interacting with humans. Those robots have to be programmed with personality, which is not one-size-fits-all project.

The ideal robot companion for humans is not quite perfect. That’s the conclusion of PhD researcher Mriganka Biswas, supervised by Dr John Murray, from the University of Lincoln’s School of Computer Science who presented their findings the International Conference on Intelligent Robots and Systems (IROS) conference in Hamburg this October, as reported in WT VOX. The research said in that article, "A companion robot needs to be friendly and have the ability to recognise users’ emotions and needs, and act accordingly. Despite this, robots used in previous research have lacked human characteristics so that users cannot relate -- how can we interact with something that is more perfect than we are?”

The good news is that it is possible to program robots to come across as more human. As the French company Aldebaran has discovered in developing culture-specific programming for humanoid robots in conjunction with its parent company, Softbank, what people would want for their humanoid robot varies, according to cultural expectations. That’s what it’s working on in developing the robot Pepper for international markets.

The controlling idea for developing a companion robot like Pepper is interaction. On one level, the robot acts like Siri on wheels. It has the ability to tap into the Internet to answer questions about the weather or local entertainment offerings. Beyond recognizing your voice and responding to what you ask, Pepper is equipped with built-in cameras and sensors that enable it to analyze facial expressions and body language to identify what a person is feeling.

Pepper communicates to humans through eye movements, what appears on the tablet it wears, and speech. What Pepper says can be neutral, playful, or didactic. Which of those three should be the default depends on the expectations of the humans around, and that’s where specialized programming comes in.

The original Pepper programming was designed for Japan, where it proved so popular that all the units available in September sold out in under a minute. However, what’s a bestseller in Japan wouldn’t make a suitable robot companion in the United States, where consumers have their own expectations for robot behavior.

“In Japan, because they have a very cute-centric culture, Pepper is much more silly and cute,” Alia Pyros, International Communications Manager at Aldebaran said in an interview with the MIT Technology Review. Examples of that kind of behavior can be seen in this video from Softbank.

In the first segment of the video, Pepper cheers up a weeping woman by playing peek-a-boo. In that context, it works, but Americans may not find that an appropriate reaction. They prefer spice to sugar, according to Pyros who pointed out that the American version of Pepper will exhibit some snark. For example, when the MIT reporter asked it a question, instead of displaying deference, it responded, “Do I have to answer that?”

In an email exchange, Pyros spoke about programming for gestures according to cultural customs. As expected “in Japan when Pepper meets someone he bows respectfully.” But Pepper units programmed for other countries may offer “a handshake or even high five.” As she explained, “Because different countries have different expectations of a social companion, we will need to adopt the personality of Pepper to suit different countries and their specific customs/traditions in interacting.”
