Global Robotic Prosthetics: The Future of Limbs
Robotic prosthetics, also known as bionic limbs, are artificial limbs that utilize sensors and computer control systems to provide motorized motion and sensory feedback to the wearer.

While prosthetics have existed for centuries, recent advancements in engineering, materials science, electronics and robotics now enable vastly superior functioning compared to traditional mechanical limbs. This new generation of robotic prostheses promises to return lost mobility and independence to millions of amputees worldwide.
Advances in Materials and Construction
Key to modern prosthetics is the development of advanced materials. Carbon fiber composites provide limbs that are incredibly strong yet extremely lightweight. New alloys like titanium are rigid yet comfortable to wear for extended periods. 3D printing now allows for custom prostheses to be fabricated with precise anatomical fits. Implantable sockets using osseointegration fuse directly to leg bones, eliminating pain and socket sores from rigid interfaces. Flexible polymers and synthetic skin give limbs a natural appearance and feel. All of these material improvements allow for greater durability, comfort and user acceptance of prosthetic devices.
Powered Joints and Motors
Whereas conventional prostheses were static extensions, new robotic limbs are dynamically actuated using electric motors, pneumatics or hydraulics. Multi-axial joints powered by brushless DC motors can replicate the complex motions of the knee, ankle, elbow and wrist. Sensors precisely control torque and speed for smooth, efficient movement resembling biological physiology. Microprocessors receive and process control signals, coordinating powered joint motions seamlessly. This enables activities like running, jumping, lifting and intricate hand manipulations that were previously impossible for amputees.
