This is Reachy, a very expressive and open-source robot developed by the French company Pollen Robotics. The robot was presented during CES this year.
Obviously, among the pros of the robot, the fact that it is based on an open-source platform capable of learning more and more. At the moment, the robot has already shown its ability with simple games, but developers can use Python to create countless applications for the system. The modular nature of the robot allows an unlimited number of applications: use within the restaurant, customer service, demonstrations is possible, and it can also be dedicated to research and development sectors.
