Context

An intelligent artificial limb has been developed by the Indian Space Research Organisation (ISRO) to promote technological advancements for welfare of the society.

Key Features:

  • The artificial limbs were named as ‘microprocessor-controlled knees (MPKs)’.
  • A 1.6 kg Microprocessor-controlled knee (MPK) enabled an amputee to walk about 100 m in a corridor with little support.
  • It has developed these MPKs under a MoU with;
  • National Institute for Locomotor disabilities (NILD),
  • Deendayal Upadhyaya National Institute for Persons with Physical Disabilities (Divyangjan) and
  • Artificial Limb Manufacturing Corporation of India (ALIMCO).
  • These limbs are likely to be about 10 times cheaper than available options.
  • Walking parameters can be set using PC-based software to improve one’s comfort. The interface plots the parameters in real time during walking.

Microprocessors and Artificial Intelligence

  • A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits.
  • The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit.
  • The processors used in artificial intelligence and machine learning-based systems are known as AI processors.
  • These are basically the neuromorphic processing units which are designed on the basis of machine learning and artificial neural network.

According to the current system of classification, there are four primary AI types: reactive, limited memory, theory of mind, and self-aware

How AI works with Brain functioning?

  • Brain-computer interfaces (BCIs) use decoding algorithms to control prosthetic devices based on brain signals for restoration of lost function.
  • Computer-brain interfaces (CBIs), on the other hand, use encoding algorithms to transform external sensory signals into neural stimulation patterns for restoring sensation or providing sensory feedback for closed-loop prosthetic control.
  • Brain co-processors can be used for a range of applications, from inducing rehabilitation after brain injury to reanimating paralyzed limbs and enhancing memory.

Advantages

  • More comfortable
  • Less costly and feasible
  • Accessible to lower strata of the society
  • Promotes equality

Recent Government Initiatives

  • ADIP Scheme: The main objective of the Assistance to Disabled persons for purchasing / fitting of aids / appliances (ADIP) scheme is to assist the needy disabled persons in procuring durable, sophisticated and scientifically manufactured, modern, standard aids and appliances that can promote their physical, social and psychological rehabilitation, by reducing the effects of disabilities and enhance their economic potential.
