YUKAI ENGINEERING specializes in the development of robots that bring joy to life. We are focused on building the consumer market for personal robots that can enhance the quality of daily life. Our goal is to see a robot in every household across Japan and elsewhere.

We believe communication robots will be the most popular form of user interface in the near future. As robots get connected with networks and various sensors, they understand user's behaviors and support the users. This will transform the ways people live. Robots will automatically know what tasks to perform and get them done. Robots will become such an integral part of our life that we may not even think about what they are doing.

Petit Qoobo

Petit Qoobo is a therapeutic robot in the form of a cushion with a tail. When caressed, it waves gently. When rubbed, it swings playfully. And, it occasionally wags just to say hello. It’s a curious presence you will want to cuddle. Its comforting communication that warms your heart the way animals do. Begin your “tail therapy” today and wrap yourself with fuzzy love.

Amagami Ham Ham

Yukai Engineering’s new form of healing called AMAGAMI HAM HAM came out from the experience of raising a child. This is a nibbling robot that reminds of the charming gestures where pets and babies gently nibble your finger with their small teeth. Sadly, you need to harden your heart and stop them to do this act. AMAGAMI HAM HAM frees all humanity from such dilemmas. The program called HAMGORITHM that brings various patterns of nibbling enables you to experience different nibbling everytime you place your finger into AMAGAMI HAM HAM’s mouth.
