Can a raspberry pi Computer  artificial intelligence robot from scratch ?

Yes, it can be possible.

yes, it is nothing difficult to  find related resources through many books and websites, however, I personally believe that raspberry pi is of quite limited capacity in programming anything that make sense in the real world,except gadget, but if you are certain that is for beginner purpose, it is fully ok to do so.

It depends on what you mean by "artificial intelligence". 

You will likely need a lot more than just one Pi, and your 

best bet would be to use cloud computing for most of 

the processing power that you will need -- which will 

unfortunately slow everything down considerably... 

so the answer to your question is: Maybe.

Yes,

it

can

done.

read that back to yourself, and tell me how that is a "question". what is it you want to know about those things? can WHAT be done from scratch?

what you have there is a fragmented SENTENCE, not a question...

A Raspberry Pi - or better still a Jetson Nano - can easily control a robot with quite sophisticated capabilities.

A jetson is vastly more powerful and capable of full video processing and image / object recognition.

However, "AI" is much overused and misused term; there is no such thing as true AI yet. There are machine learning algorithms etc., but they are nearer to complex database correlations than to brain-type intelligence.

It's probably going to be another 20-30 years before a top supercomputer will be fast enough to simulate anything anywhere near as complex as a human brain.

In the meantime, have a look at James Bruton's channel on youtube for some robotics  examples with full programs / software details and hardware designs freely available.

If you search "Opendog" on youtube it will take you straight to his stuff.
