"Drawing Kokko" is a very unique and epoch-making robot that has no precedent in the world with a drawing function. Focusing on the fact that coloring books have a great effect on the mental activity of young children, it is an excellent product that allows young children to become familiar with English in a playful and fun way, and has already been exported to the United States and many other countries. The brain moves the sensory organs of the body in different areas, but the development of those brain areas is not uniform. The development of hearing to distinguish sounds peaks at the age of 4~6 years and levels off after that. It is during this period that children in Japan also rapidly increase their vocabulary of words. On the other hand, the area of movement of the limbs develops at the age of 6~8 years. In other words, in order to acquire the hearing to distinguish the sounds of English, which has more vowels than Japanese, it is necessary to be exposed to English sounds as much as possible by the age of 4~6. What makes this robot revolutionary is that it emits English words while drawing shapes, inspires young children to color shapes, and uses the three brain regions of sight, hearing, and touch while having fun, and fixes English words in the brain as memory. Did you know that coloring books are also used as a brain teaser for the elderly? There are two types of human memory: short-term memory, which is temporarily stored in the hippocampus of the brain, and long-term memory, which is recorded in the cerebrum. We can speak Japanese because we record words in our cerebrum as long-term memory.
