Fiber Optics Add Sensitivity to Robot Touch

Fiber Optics Add Sensitivity to Robot Touch
Sep-30-15
Researchers have developed a fiber optic-enhanced robotic hand that could make it significantly safer for robots to work near people.

Created by a team from Carnegie Mellon University, each finger of the three-fingered hand mimics the skeletal construction of human fingers. Each of the silicon-covered fingers are embedded with fourteen fiber optic strain sensors, which allow the hand to detect forces less than a tenth of a newton. The system incorporates the fiber Bragg grating sensors, which monitor strain by measuring the shifts of wavelength in light reflected by the optical fiber.

The team has also created a new type of stretchable optical sensing material that was not used in this version of the hand.
