New robotic technology offers internalised sensing capabilities

Researchers have developed a soft-surface robotic hand that is able to feel and sense its surroundings internally in a more organic manner than is currently possible.

The Cornell University team have developed a means of using stretchable optical waveguides to act as curvature, elongation and force sensors in the robotic hand, rather than the bulky, rigid mechanised means currently used for sensing.

This optoelectronically innervated prosthesis deforms as it comes into contact with objects, meaning more light is lost through its core. This variable loss of light is detected by a photodiode, allowing the hand to sense its surroundings.

Subsequently, the hand was used to carry out a variety of tasks, including grasping and probing objects for both shape and texture. It proved capable of handling three tomatoes and determine which was the ripest by assessing their respective firmness.

Doctoral student Huichan Zhao, the lead author of this study, said: "Most robots today have sensors on the outside of the body that detect things from the surface. Our sensors are integrated within the body, so they can actually detect forces being transmitted through the thickness of the robot."
