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]
