Microprocessor-Controlled Smart Limbs
  • Microprocessor-Controlled Knees (MPKs) will assist the above-knee amputees to walk with a comfortable gait.
  • According to ISRO, the MPKs will offer extended capabilities to the amputees in comparison to the passive limbs which come without the microprocessors.
  • The MPKs are being developed with a partnership between the VSCC, and Pt. Deendayal Upadhyaya National Institute for Persons with Physical Disabilities, the National Institute for Locomotor Disabilities (NILD), and the Artificial Limb Manufacturing Corporation of India (ALIMCO).
  • Currently, the MPKs are imported into the country and cost between Rs. 10 lakhs- Rs. 60 lakhs. ISRO aims to make the indigenous MPKs commercially viable by bringing their cost down to Rs. 4 lakhs- Rs. 5 lakhs.
  • The MPK consists of a microprocessor, load and knee angle sensors, a hydraulic damper, a lithium-ion battery, a composite knee case, an electrical harness, and interface elements.
