Afghanistan doesn’t have enough ventilators.  So an all-girl robotics team at a high school there came up with a new one that’s cheap and easy to make…

In the city of Herat, the Afghan Robotics Team of 7 young girls finished the design of an open-source, mobile ventilator that costs as little as $700—compared to the $20,000 needed to purchase a traditional model. The lightweight machine can be powered by batteries that can run for ten hours.

They were among esteemed company, too, as their design was partially based on an MIT blueprint, and they received support and guidance from robotics experts at Harvard.

“We are delighted that we were able to take our first step in the field of medicine and to be able to serve the people in this area as well,” Somaya Faruqi, an 18-year old member of the robotics team, told Reuters. “All members of our team feel happy because after months of hard work, we were able to achieve this result.”
