Yukai Calls on All Its Robotic Kit Users to Show Off Their Ingenuity in Its First ‘kurikit’ Robotic Contest

2020/5/14 News

As part of its educational product and program series known as “kurikit,” Yukai Engineering will host its first ever homemade robotic contest (“Uchi-robo contest”). Kurikit is aimed to help the young and adults learn robotics while having fun. In the contest, people of all ages can use the company’s “create-a-critter robot kit” to build robots and show off their best work by submitting them via social media.

For more information about the contest, please visit:

The “create-a-critter robot kit” enables anyone, including elementary school-aged children, to easily build robots. Contest participants are asked to use the kit to build “really interesting” robots. Zariganiworks Co., Ltd., the company that designs and develops toys, will serve as the special guest juror for the contest. We look forward to seeing lots of unique innovative submissions from all corners of the country!

We would also like to let you know that NHK Enterprise, the organizers of Elementary Kids Robocon, and Yukai will collaboratively host a workshop titled, “Do it at home! Online robot-making workshop,” on May 29 and May 30, while the contest is ongoing. Any elementary school children in the lower grades can participate in this workshop to create robots with Yukai’s “create-a-critter robot kit.” Yukai’s staff engineer Yoshihisa Wada, who himself has had the experience of participating in a high school robocon, will teach the students “the wisdom of monozukuri (crafting).” All participants will join the workshop remotely via online.

We are spending a lot of time at home right now, and it’s a great time to try making things! I hope you will discover the joy of making robots from your original ideas while at home.
