HAPTIX is a DARPA program designed to "develop new science and technology to achieve closed-loop control of dexterous mechatronic prostheses that will provide amputees with prosthetic limb systems that feel and function like natural limbs". OSRF, the organization maintaining Gazebo, has been tasked with extending Gazebo to simulate prosthetic hands and test environments, and develop both graphical and programmatic interfaces to the hands.
