TOKYO: A wise-cracking humanoid robot called Pepper whose makers claim can read people's emotions was unveiled in Tokyo last month.
Mobile carrier Softbank, which created the robot, says Pepper can understand 70 to 80 percent of spontaneous conversations - although it also answers from a set number of pre-programmed responses.
