Pepper

A 120 cm semi-humanoid social robot developed by SoftBank Robotics (originally with Aldebaran Robotics), featuring articulated arms with 20 degrees of freedom, LED eyes capable of gaze behaviours, an animated face, and a chest-mounted tablet for touch interaction. Pepper is widely used in accessibility, education, and care research because its human-like proportions encourage social behaviour such as greetings and eye contact. However, its humanoid appearance can raise user expectations of conversational ability beyond what the robot can deliver, particularly for users with intellectual disabilities.
