Scientists have discovered a way to give robots a sense of touch without the need for expensive artificial skin.

A team from the German Aerospace Centre instead used artificial intelligence to interpret the signals from a robot’s internal sensors in order to accurately detect external force and pressure.

The researchers said the new approach would negate the need for costly biometric skins and sensors, while also enabling a “shift from conventional modalities towards adaptability, flexibility, and intuitive handling”.

A concept built by the team includes virtual buttons, switches and slider bars that can be freely placed, moved and configured in any location on the robot’s structure.

The setup allowed the robot to detect physical interactions without needing specific touch sensors.

The accuracy of the machine learning algorithms meant that the robot was even able to detect when numbers were traced on its surface, which could potentially allow entirely new ways for humans to interact with robots.

“We were able to let the robot sensitively feel the surrounding environment and accurately localise touch trajectories in space and time that were applied on its surface by a human,” the researchers wrote in a study detailing the technological advancement.

“This opens up unexplored opportunities in terms of intuitive and flexible interaction between humans and robots.

“The intrinsic sense of touch we proposed in this work can serve as the basis for an advanced category of physical human-robot interaction that has not been possible yet, enabling a shift from conventional modalities toward adaptability, flexibility, and intuitive handling.”

The study, titled ‘Intrinsic sense of touch for intuitive physical human-robot interaction’, was published in the journal Science Robotics on Wednesday.
