Repetitive tasks cause frequent injuries Injuries to knees
Normal gait cycle Lifting medium to heavy loads
DARPA Warrior Web ProjectDeveloping exoskeleton for military and civilian purposes
Reduce load on person carrying 100+ lbs. of equipment
Reduce injuries due to reparative actionsStress-Strain relationship between exoskeleton and human
Passive activation for minimal energy use FEA analysis of components
DARPA Warrior Web ProjectRapid response to prevent injury
Controllable stiffness to harvest and redistribute energy
Pneumatically driven for rapid response
Sensor layerControl system
Data to OpenSim for inverse kinematics and eventually forward dynamics
