RIS2
DARPA – Prosthetics Program Vision
Exploit state of the art technologies:
actuation, mechanical power distribution, energy storage, biotic/abiotic interfaces, sensors, computation, and neural control
To
Provide fully integrated limb replacements that enable victims of upper body limb loss to perform arm and hand tasks with strength and dexterity
State of the Art Today
Myoelectric or “shrug” control with a standard harness and socket interface
2007
• 8 lb grip, 10 lb wrist flexion, 20 lb elbow flexion-extension • 24 hr power system • Environmentally Robust • Local Reflex Control
Mechanically Superior
2009
Closed loop nervous system integration Full DOF, range-ofmotion Proportional tactile & force receptors Human-like endurance and actuation
Neurally Integrated
Slide 4 RIS2 not necessary for the slide...but as part of the talk you could state that the model used to develop the 2009 metrics was, simply, the human arm. That is what we want, that is how we set the bar.

DARPA – Video
Revolutionizing Prosthetics Program-Video Presentation
DARPA – The HAND Program
Vision:
Use signals from neural activity to do work; command, control, actuate, and communicate with peripheral devices and systems for restorative applications to the warfighter
Develop optimal coding and processing for control of a peripheral device such as a prosthetic arm
Examine restorative applications involving motor function and pattern activity associated with memory
Identify new techniques for non-invasive access to neural activity
Impact: Providing the best for America's warfighters.
DARPA – The HAND Program
Use brain activity to command, Use brain activity to command, control, actuate and communicate control, actuate and communicate with the world directly through brain with the world directly through brain integration with prosthetics and integration with prosthetics and peripheral devices peripheral devices
• Closed loop demonstration of arm reach and grasp of food • Open loop demonstration of human control of gripping force • Long-term compatibility • Non-invasive correlates
DARPA – FISST Concept
FISST Vision
• Stable Skeletal and Cutaneous Integration of Prosthetics • Seamless Interfacing of Tissue Engineered Constructs • Lifetime Stability • Correct Alignment for Natural Transmission of Forces
DARPA – FISST Concept
Osseointegration
• Osseoperception (proprioception) • Counters distraction forces for UE amputees • Removes concern over residual limb volume changes • Eliminates pressure-induced skin breakdown
Skin Integration
• Continuity of barrier function • Microbial barrier • Fluid loss • Reduced need for grafting or skin substitutes
Muscle Integration
• Unmatched actuator versatility • Definable neural connectivity for voluntary control
Tendon & Ligament Integration
• Structural continuity with implanted materials • Muscle-to-bone • Bone-to-bone • Proper integration of tissue engineered bone, muscle & connective tissue
DARPA – Future Applications • Revolutionize Prosthetic Industry • Neural Control of External Devices • Restore Vision • Restore Locomotion to Paraplegic/Quadriplegic
Improve Quality of Life and Return the Warfighter Back to Duty
