Karakuri IoT
Yuji Yamamoto, MDH

Agenda
• Karakuri IoT concept
• Demo: Karakuri IoT kit
• How we work with the companies
• Use Karakuri IoT for education

What is Karakuri IoT?

Karakuri dolls made
during 1800’ in Japan
Karakuri:
“apparat/pryl som
skapades med kreativitet”

Karakuri Kaizen - Simple mechanical automation
often made by shop floor workers
• Do-It-Yourself Low
Cost Automation
• Empowerment
• Learning new skills

Simple IoT at Home (self-making home automation)
Mobile App
Tells the mobile
when the flower
feels thirsty
Cost: 100 SEK, Time to build 15 minutes

Project objectives
Develop a modular IoT kit
for non-experts
Develop work methods
for improvements using
IoT + creativity of many

(Nikkei Monozukuri, 2016)
”When we discuss
use of IoT in factory,
I always ask how
people can be
developed with
this”
(Toshiyuki Isobe: Chief officer at
Frontier Research Center, Toyota)
