Japan's consumer robotics scene is famous for creating gentle, unassuming companions rather than task-performing androids. Two standout examples of the japanese companion robot philosophy are Panasonic's NICOBO and Yukai Engineering's Mirumi. While both embrace vulnerability and slow pacing, one is a 1.5 kg home cushion with a subscription plan and the other is a 155 g app-free charm that clips onto your bag.
