More than 35 million people around the world have lost a leg. 300,000 of these are in Indonesia alone. Many of the prosthetic legs currently in use emphasize visual appearance, and while they are affordable, they have problems in terms of functionality and comfort. This project was launched in the hope of solving these problems and thereby helping people who have lost a leg to regain their self-respect and economic security. The project team re-examined each component of the prosthetic leg one by one and introduced a number of improvements that succeeded in boosting functionality while keeping costs low. The long-awaited "B.L.E.S.S. foot" prosthetic leg was born. The team is continuing its work to achieve a free and equal lifestyle for all human beings.
