In Japan, the oldest robot is "Karakuri ningyo." This is a small doll, so this doll's machanism is very easy.It made of wood and these power is spring.
In 18 cdntury, these dolls were made. These are called "Tyahakobi ningyo" , they can carry tea. These are unusual in those days, so many rich people wanted to get its.
Recently, "Robot" express machine, say, "ASIMO" and "AIBO". These are very delicate compared with "Karakuri ningyo". This is remarkable progress. What robot will be maked in hundreds years?

I use a mobile phone in my daily life. It is useful, but there are some people who use it anywhere. These conducts trouble other people.
For example, in the bus, in the train, and in the hospital. These places prohibit pople from using mobile phones, but some people use it. I don't understand there conducts.
Now, companies which sell mobile phones caution about mobile phone's manner.(For example KDDI,and NTT) It circumstance is miserable. I hope people notice this problem and improve it.

It is very difficult to live in outer space. Most difficulty problem is about food. So, scientists proposed project. This project’s summary is self-sufficiency in outer space. So scientists began to experiment in Bio Sphere2. It was 9/26/1991.

Bio Sphere2

Bio Sphere2 was built as model of ecosystem. They were going to live in Bio Sphere2 for two years and they were going to continue this experiment for 100 years.

Inside of Bio Sphere2

But this experiment was failure. The experiment was breaked off. It was continued only 2 years. They could'nt copy ecosystem completely.

This experiment showed it is very difficult to live only self-sufficiency in outher space. It takes many time to live in outher space lengthy.

I have audio player. This player's storage capacity is 256MB. I bought it 8 months ago. Its price was about 15000 yen.
It is very useful. I use it when I ride a bike mainly.
But I feel complaint it, because its storage capacity is small.


It is my audio player.
I told that it storage capacity is 256MB and price is about 15000 yen a little while ago. We can buy audio player which storage capacity is 1GB for about 15000 yen now.

iPod shuffle

For example "iPod shuffle". Its storage capacity is 1GB and its price is about 17000 yen.
I want to change my audio player.

About cars 

2005年10月24日(月) 9時14分
I got a driver's license last year. But I seldom drive a car and I am not interested in cars.
I think the car is very convenient machine. But if we mistake drive, cars will become danger machine.
Car accident is very awful. So I hesitate to drive a car.
Recently I got "SD(Safe Driver) card". This card proves no accident and no violation.
I want to safety drive to keep having this card.

I want to sleep...
