A team of students at the University of Washington is trying to make prosthetic limbs a lot more affordable. 

They are using desktop computers, a video game controller and a 3D printer to reinvent the technology that allows amputees to gain some mobility. 

When a team of students decided to transform the technology inside prosthetic limb, they first went shopping. 

Their task was to create a prosthesis that is much cheaper than what is currently on the market. 

A $200 armband was designed to control video games or Powerpoint presentations, but by sending its signals through a cheap desktop computer, the student figured out they could manipulate a hand, which they made usinga 3D printer. 

The project is still a work in progress, but the student hope others will help advance the technology further using a free online database. 

They think an even better version is within reach.
