Bonds Built Through Exchanging "Things"
■ From "words" to "things" When we discuss attachment to robots, attention tends to go to interface refinements like voice or expression. Episode 31 shows a more ordinary path: a handmade "safe driving" charm sticker placed on the tray, alongside the medicine. This small exchange of a physical thing turns a robot from a "tool" into something people care about.
■ Designing the tray as "open space" Hakobukun's tray functions not only for delivery but as open space where things can be received. A place to set something down, a surface for a sticker — this receptiveness lets spontaneous exchanges happen. Designers cannot design attachment itself, but they can design the room for it to grow.
■ Conclusion: stickers as a "record of acceptance" The new sticker is not mere decoration. It is a record of being accepted by the team, a visible sign of a co-creative relationship. These small exchanges, absent from any spec sheet, are what make a robot a member of the floor.
