In 2014, SoftBank Robotics introduced its inaugural emotional robot, Pepper. Pepper is an affable and emotionally attuned humanoid robot, purpose-built to serve as a helpful assistant. With the ability to recognize, comprehend, and respond to human emotions, Pepper boasts a range of interactive features, including a 3D camera, omnidirectional wheels, and directional microphones, enabling it to engage in autonomous and intuitive communication.

Moreover, Pepper transcends traditional robotics by learning through its experiences and being Android-compatible. This means that programmers can harness SoftBank's software development kit to tailor technologies for Pepper, continually enhancing and broadening its capabilities.

NAO stands at a modest height of 60 cm and is a creation of Aldebaran Robotics, a company based in Paris, France, and a part of the United Robotics Group. This remarkable humanoid robot made its debut in 2008 and has undergone several iterations since. NAO finds wide-ranging utility in educational and research contexts, even trying its hand at sports through participation in the robotic football league, RoboCup.

NAO's sensory arsenal includes 7 touch sensors on its head, hands, and feet, in addition to sonars, two 2D cameras, and an internal unit for self-localization and spatial mapping. Equipped with built-in microphones and speakers, NAO excels in human interaction, understanding speech in 20 languages and responding intelligently.
