Prosthetics currently, are more controlled by robots than humans. The AI being used developed only the assisting ability but not the consciousness of its own that we currently know of.

Function: How does a prosthetic work and why AI was significant in performance. A prosthetic operates with a brain computer interface, consisting of 4 phases, signal acquiring, processing, device output and operating control. The first step is electrodes acquired and processed brain signals, the chip was attached to the skull through surgery without penetrating electrodes into the brain. Effectively connecting the brain and the prosthetic through a wire that can send signals from the brain and to the brain. Detecting mu and beta rhythms to be translated into movement. However, invasive signals record muscle movement more accurately. Such as the further placed into the brain or sending signals which bounces back. Occasionally a camera-like sensor that allows the user to ‘see’ and feel the object in ways like pressure and temperature. The camera also allow function for AI to assist with intelligence such as when the leg saw an obstacle, it will alert the limb to act accordingly.

The second step is signal processing, a more complicated process consisting of extraction and translation of signals. During the extraction phase the brain sends a whole series of different functions, when different algorithms are applied to identify the user’s intent. The algorithm adapts to the user at 3 levels: first the algorithm will adapt to the signature feature rhythm the user uses. The second adaptation was to spontaneous changes, such as intensity of signal. This is when AI is a significant and widely used role. To permit personalization, affordability, adaptability and to meet everyday demands.

The third adaptation was used to adapt to the brain itself, to hopefully improve the interface through feedback and get both device and brain used to each other. Over time the algorithm will reward and train the brain to be capable of faster communication. The more precise the extraction the better the algorithm, and the more extract signal to noise ratio will be. The third step is when the output from BCI sends an actuarial signal to the machine to perform. Such action can be anything. Such as controlling a cursor on the screen.

In the part to identify and adapt to brain signals, AI and the software update part of it was frequently used to smoothen the user experience and make it more personalized, accessible to people who are in need.

Maintenance: The cost and risk aspect of affordable prosthetics. Body powered prosthetics can include using the other functional body park to act as a brake mechanically, while externally powered include motors that turn on by a button. As for function, charging was essential. And smooth, effective use will require software update and regular parts maintenance. For example, the motors on the prosthetic were individually installed for natural performance such as holding an egg. The physically risky side of surgery needed and the constant adjustment for the body from prosthetics are known to hold damage that can result in high risk. Most victims of limb loss include vascular disease, artery disease and diabetes, which caused half of all amputees in the US, while trauma majored the cause of the other half. This population mostly were older people. Paying for the expensive device was tricky as the development of it through insurance, since a good deal of people choose not to wear them.

An effective alternative without AI: assistant wearable gear before damage being done This method will require less AI, perhaps merely the implication of radio and more permanent assistance such as the exoskeleton developed by the US military, allow ordinary people to hike farther and lift the previously unbearable, currently booming in the market yet their biggest barrier is simply power storage. Such a device will allow Stephen Hawking to walk again. Although incredibly tough, one malfunction, especially at the power supply, will disable the entire system. There are armor options which operate entirely without AI, the briefcase expandable armor but too heavy in practice and induce blisters during use. The quest for effective armor comparable to spacesuits remains the ultimate pursuit.
