This content will give those brilliant ideas as follows..: Design of Friend Robot, more friendly than your friend: my Personal Assistant Robot in 2030: Walking with Robot than Pets: Ideas for Animal 'Body & Brain & Sensing' Architecture: Convergent strategic Approach to max. Robot Value: Story to persuade $1B Robot Investment In the natural environment of animals or human artificial social environments that have been operating with muscles and bio-brains for hundreds of millions of years, there will be large and small limitations for devices such as robots controlled by digital motors to play many roles flexibly. I am sharing some approach ideas to pioneers who feel that limitation, and I expect them to make additional contributions to the future of humanity. And, it mainly deals with convergence technologies such as sensing organs, brains, and flexible bodies that mimic animals from a macro perspective. "Personal leisure time" is being increased by the development of human civilization such as 'mechanization, automation, industrialization, AI', and "the time of old age" is also being greatly increased due to the prolonged lifespan due to medical development. The moments of a lonely or needy will be more likely to increase in our life's leisure time. A robot that includes all of the specs like "flexible physical body, biological brain based computing and memory, efficient convergence sensing" that resembles an animal, that will become a "friend or personal assistant" for those moments/times of high value. That's also why it looks attractive. The biological brain part will be the bottleneck. However, I think that part is worth approaching as a two-sided strategy of the development of SW architectures at various levels and mid- and long-term investment in understanding of bio-brain. It will evolve in the direction of installing appropriate services and software for each application field in HW architecture of various performances. I believe that this contents are also offering a variety of approaches from a business and developer perspective for devices and services that will support humanity in responding to these changes in the environment. It seems to be effective, if you take an approach to applying the concept to 'the brain system architecture and SW' for the various devices that have an animal instinct. The concept is that "The brain of the organism instinctively like to remember important factors such as 'food/clothing/shelter, survival, awareness of environmental change, pleasure, pain, sadness, happiness, love, desire, honor/showoff/contribution in society activities', according to "the priority in their each living environments", and the brain & sensing parts & physical parts evolve at an appropriate rate(but, not fast) as needed." Just as it is different for each person in the same space to see and remember, it will be important to understand what events are of interest and focus for each individual with limited capabilities and performances, such as sensing, time, and memory. Rather, programming of psychological operating principles about which mechanisms create individual attention and concentration, it seems to be much more helpful. Rather than creating an inefficient supercomputer that sees and understands everything, the approach of creating what is needed on an ordinary personal level seems better. Let's remember that the risk of relying on a huge system or only one person is far greater than the risk of an organization operating with a large number of incomplete collaborations. In particular, risk distribution seems to be the best way to overcome numerous threatening events over tens of millions of years and maintain the sustainability of certain life. When studying, discussing, and imagining, this is a collection of memos taken before the flashy ideas of the moment evaporate into the air.
