Bio-mimetic Robotics

What Is It?

ONR's Bio-mimetic Robotics Program extracts principles of sensorimotor control and biomechanics from biological systems to design advanced vehicle prototypes that exceed current engineering capabilities.

How Does It Work?

Efficient propulsion mechanisms based on animal bio-locomotion are combined with adaptive nonlinear neural controllers and bio-inspired sensing and navigation to produce new vehicles that are efficient, low-noise and agile.

What Will It Accomplish?

Bio-mimetics Robotics expand the operational envelope of naval autonomous systems.  Enable autonomous underwater vehicles that are both maneuverable and long duration.  Enable underwater vehicles that are stealthy and agile.  Enable UGVs that can support human robot interaction and act as peer teammates with warfighters.

The Office of Naval Research’s Bio-robotics Program in legged robotics led to DARPA’s Big Dog robot.

ONR’s Bio-mimetic Robotics Program has a primary focus on bio-inspired autonomous undersea vehicles. Neuroscience research into motor control circuit controlling movement patterns led to nonlinear physics models of coupled neural oscillators encoding command sequences in phase. Nonlinear controller was built in analog VLSI and demonstrated to produce precise adaptive synchronization of a six-foil underwater vehicle.

Analysis of fluid dynamics of fly wing and fish fins led to new principles for high-lift propulsion due to dynamic stall mechanisms. High-lift pitching and heaving foils developed at the Naval Undersea Warfare Center have been able to capture this efficient propulsion on a prototype underwater vehicle. This vehicle is quiet, highly maneuverable and capable of operating for weeks with current battery technology. Research into muscle-like actuators, bio-sonar and flow sensors has also been supported.

The technology behind the Bio-mimetic Robotics program are bio-inspired autonomous undersea vehicles that use the principles of animal locomotion and neural control, and bioinspired sensing that demonstrate improvements in stealth, efficiency, maneuverability, and mission duration over existing engineering technologies.

These new bio-mimetic technologies will offer future Warfighters persistent, long duration missions by highly maneuverable vehicles capable of positioning sensor arrays.
