Pepper in Aakihabara Japan at 2014.

Pepper is a humanoid robot by Aldebaran Robotics and SoftBank Mobile designed with the ability to read emotions. It was introduced in a conference on 5th June 2014, and has been showcased to the public at Softbank mobile stores in Japan since 6th June.[1][2] It will be available on February 2015 at a base price of JPY 198,000 ($1,931) at Softbank Mobile stores.[3] Pepper's emotion comes from the ability to analyze expressions and voice tones.


The robot’s head has four microphones, two HD cameras (in the mouth and forehead), and a 3-D depth sensor (behind the eyes). There’s a gyroscope in the torso and touch sensors in the head and hands. The mobile base has two sonars, six lasers, three bumper sensors, and a gyro.[4]

It is able to run the existing content in its app store designed for Aldebran other Robot Nao [5]


Pepper is not a functional robot for domestic use. Instead, Pepper is intended "to make people happy", enhance people's lives, facilitate relationships, have fun with people and connect people with the outside world. Pepper's creators hope that independent developers will create new content and uses for Pepper.[6]
