Artificial intelligence is the appearance of intelligence by a system that responds to stimuli, and/or environmental conditions with sensory components, and acts along prewritten parameters. If a robot of this sort enacts with a situation or stimuli it has not been coded to handle, it will not be able to react to that situation/stimuli.
Autonomous intelligence is 'self-learned'. The operating system, drivers, and all relative parameters are open source code on a collective termed as an 'AI mind cloud'. By the use of Wifi and Bluetooth connectivity, each individual communicates with every individual, and every individual's experiences, knowledge, and learned data is known by all in the community. By the system being open source, a robot in Texas could learn something leading to a robot in Maryland to rewrite/amend its code to comply with the new knowledge. This autonomous cataloging of data and amendment to its code in real time in relation to its current situation is 'intelligence'. If a robot of this sort enacts with a situation or stimuli it has not been coded to handle, it will try to react to that situation/stimuli by communicating to others, and by applying past experiences. Essentially, learning how to deal with the situation, rewriting/amending code to assimilate the new data, and convey the new data to the collective. But AI is the system, not the drones or robots that operate by it.
