“Moflin” by Casio – the company best known for digital timepieces such as G-Shock and Baby-G – reportedly demonstrates over four million distinctive personality traits, recognising the person who talks to it frequently as its owner.

It gradually learns what the owner likes based on interactions such as petting and cuddling. The robot is also designed to develop its own simulated feelings and personality, which can change over time.

With regular interaction, it will become happy, secure and calm. If it’s ignored, it can become stressed, anxious and sad – much like humans.

“Development began with women as our target audience. We imagined a sidekick that could provide support even when you’re facing issues at work or in your personal life,” said Erina Ichikawa, who led the team behind Moflin’s development.

The project gained momentum after an engineer from the company brought in a prototype robot for the purpose of portraying the cuteness of small animals. Casio, which launched the AI pets in November, exceeded its target and sold over 7,000 units by March.

They are particularly popular among women in their late 30s and early 40s, according to the company. Ichikawa notes how some people also bring them on excursions on days off.

“People can feel that their Moflins are different from other Moflins, as the robots – like animals – display individual personalities and emotions, on top of growing and having varying sleep cycles,” Ichikawa said.

The robots are priced at 59,400 yen (RM1,711). The company also provides add-on services, including a so-called “salon” that washes and cleans the robots’ fur.
