Background of birth of "wakamaru"

The first inkling of "wakamaru" lies in a company project titled "MHI Frontier 21," started in 2000.
In order to start a new product/project with a 21st century theme, ideas were canvassed from all employees. Then, one of the proposals summarized by the investigation team, mainly consisting of younger employees was, the "Service Robot Project."
MHI has produced robots working at places where human beings cannot safely work, such as the check robots at nuclear power plants and robots working in vacuum conditions.
"wakamaru" was born. A robot that can live with human beings, enriching the quality of life.

Future of "wakamaru"

In 2005, we sold "wakamaru" on a limited basis to ordinary households.
When "wakamaru" was first seen, it raised great expectations from customers because of its life-like appearance, but "wakamaru" was actually poorly equipped to respond to a broad variety of needs, and many modifications had to be made.

We received, on the other hand, evaluations from the employees of those companies that were using wakamaru. They told us that "wakamaru" had its charms and an enticing character and presence. It was considered safe and the robot could be used in the fields of reception , as a guide, and to advertise events.

So, we decided to ask companies to first use "wakamaru," and then develop new functions, and have attempted modifications to increase the charms of "wakamaru" through contact with ordinary customers at events, etc.
By reflecting flexibly the experiences and technologies so obtained, we are ready now to lease "wakamaru," working in tandem with a presentation system to be used at public events.

We will go forward to the future while expanding wakamaru's field of activity so that the robot may become ever more useful and have a chance to re-unite with families in the near future.

"wakamaru" overseas rental service is currently not available.
