◯ A robot that heals the hearts and minds of all generations, from children to adults
◯ Can be lifted by small children and is not easily broken even when handled roughly.
◯ Elderly people can take care of the robot without having to stoop or bend at the waist.
◯ Security features to protect the house
◯ Flexible response to any unusual behavior of the owner
◯ No mechanical noises during operation
◯ Can play a nursing role like a guide dog or a hearing dog

◯Compensates for the shortage of guide dogs, hearing dogs, and service dogs
◯Reduces the emotional burden of pet loss
◯Reduces the physical and financial burden of pet care

We repeatedly created and improved prototypes using EV3 with the idea that such a pet robot would be wonderful.

◯Detects obstacles
　→Stops and barks when it detects an obstacle.
　→Goes forward when no longer detecting obstacles
◯Mode switching by color sensor
　→Green: Watchdog mode
　→Blue: Running mode
　→Yellow: Guide dog mode

Although we were able to implement functions such as walking in the park, running around, stopping when an obstacle is detected, and security functions like a guard dog, the following problems remained.

◯Failure to detect and respond to obstacles
◯Mechanical movement
◯Mode switching is not smooth
◯Cannot handle steps such as stairs and water areas such as bathtubs.

We had a lot of fun working on the development of robots in collaboration with local companies and on familiar issues in our daily lives. Above all, we felt happy when "people" were pleased with our work. We also had the opportunity to interact with people from other schools, such as Yoshino High School and Hokkaido Asahikawa Agricultural High School, through zoom and research presentations. I was happy that the knowledge and skills I usually learn at school could be useful.
