Therapy cushion that can help comfort people


Yukai Engineering is a small robotics startup made up of designers and engineers who love to create robots. Our mission is to use robotics to make our daily lives more fun and fulfilling!

And now, we’re developing Qoobo, a therapy cushion that can help comfort people.
Qoobo is a robot in the form of a cushion with a tail. When caressed, it waves gently. When rubbed, it swings playfully.

Qoobo can currently be pre-ordered, and will ship this autumn in Japan and the United States, and is planned in 2019 for Europe. The pre-orders have already exceeded 3000 units, and we are expecting to ship 20 thousand units in the first year.

In Japan, many people living alone or in rented accommodation cannot keep pets even though they would like to, and these are one of our target audiences. After showing Qoobo to various people, we realized that it could also be aimed at the elderly people. Subsequently, we have started trials at an elderlies facility linked with a university.
