Who has developed an microprocessor-controlled smart limbs (intelligent artificial limb)?
A)
NASA
B)
JAXA
C)
Roscosmos
D)
ISRO

Correct Answer : Option (D) - ISRO


As a spin-off of Space technology, ISRO(Indian Space Research Organisation) develops an intelligent artificial limb likely to be commercialised soon, expectedly cheaper by about ten times, benefitting above-knee amputees to walk with a comfortable gait. 
 
These ‘microprocessor-controlled knees (MPKs)’ offer extended capabilities for the amputee than those offered by the passive limbs that do not use the microprocessors. 
 
Thus far, a 1.6 kg MPK has enabled an amputee to walk about 100 m in the corridor with minimum support. Efforts to improvise the performance are underway.
 
These smart MPKs are being developed by Vikram Sarabhai Space Centre (VSSC), ISRO under an MoU with National Institute for Locomotor disabilities (NILD), Pt. Deendayal Upadhyaya National Institute for Persons with Physical Disabilities (Divyangjan) (PDUNIPPD (D)), and Artificial Limb Manufacturing Corporation of India (ALIMCO).
 
Configuration and working : An MPK consists of a microprocessor, hydraulic damper, load & knee angle sensors, composite knee-case, Li-ion battery, electrical harness, and interface elements. 
 
The microprocessor detects the state of gait based on the sensor data. The control software estimates the real-time damping needed to attain the desired gait by changing the stiffness of the system that is achieved by a hydraulic damper operated by a DC motor. Walking parameters specific to amputees can be set using PC-based software to improve one’s comfort. The interface plots the parameters in real time during walking..
