VR Interfaces: Jaipur Foot


Overview of Jaipur Foot
Created in 1971, the Jaipur Foot is a prosthetic for the third world. Cheap to make, locally manufactured, and completely, deliberately unpatented. Named after the small town of Jaipur where it was invented, the foot was the brainchild of Dr. Sethi.

25 countries across the developing world use this foot, which is unautomated, possesses no AI, no load calibration, no haptic control. It is basic, but so is the price tag - 30 usd each. Ideal for the environment in which they are needed.

Simple and cheap does not have to equal a rigid foot however. This lesson has seemingly been forgotten in many modern prosthetic designs. A foot made out of several pieces of vulcanized rubber, connected and infilled with sponge rubber. The joints between the two are the same as the joints with an organic foot, allowing the foot to flex and bend as pressure is exerted, in natural ways. It may be worn with shoes or without shoes depending on the desire and the need of the patients.

It is very flexible, allowing the wearer to run, climb trees or even pedal. It is well suited to the needs of many Asian countries in which most people sit, eat, sleep and pray on the floor. Using the Jaipur foot, a Bollywood actor and dancer, Sudha Chandra, was even able to perform a demanding dance sequence in the movie musical "Nache Mayuri."
