Limb Prostheses and Artificial Intelligence: Modern Technology`s Prospects
Modern science helps to improve many of the things we use. In particular, limb prostheses that disabled people had in the last century are fundamentally different from what modern technologies offer. The functionality of the prosthesis is being improved every year, but still, the limit of perfection is still not reached. First of all, this concerns the accuracy of movements, lacking such an important option as the force control when interacting with various objects. There are still many unresolved issues, and prosthesis developers see artificial intelligence as an effective means to solve them. To get an idea of ​​the problems of prosthetic limbs, you need to imagine how a person with an arm amputated below the elbow can manipulate a modern smart prosthesis. The most advanced device “continues” the arm and attaches to the remaining tendons and muscles. For example, if a person takes a certain object, then one is not able to evaluate its size, weight, surface character, because of the lack of fingers` tendons and muscles control, of course, there is no way to fully interact with the object, evaluating its parameters in the same way as with a real hand. As a result, the subject may fall or be damaged due to incompetent holding strength. [caption id="" align="aligncenter" width="517"] Source: Epfl.ch[/caption] Swiss researchers at the Polytechnic School EPFL (Lausanne) have developed a machine learning system, which collects and analyses muscle signals that that happen during all kinds of manipulations with a real limb. As a result, artificial intelligence masters capturing various objects, which provides reliable keeping, changing the force for a split second before a possible fall. The result of the study was a development that provides fairly careful holding different kinds of subjects. The option “Do not drop or damage” is set individually for each prosthesis user. At this stage, AI technology needs a number of improvements and the collection of additional information. EPFL developers do not exclude the creation of prostheses of the hands, fingers, feet. Flexible technology can also be used to develop an individual prosthesis for each user or to integrate a ready-made technological solution.
