Robot hands gain a gentler touch




Inexpensive tactile sensing technology builds on tiny barometer chips that are widely available

What use is a hand without nerves, that can't tell what it's holding? A hand that lifts a can of soda to your lips, but inadvertently tips or crushes it in the process?

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have developed a very inexpensive tactile sensor for robotic hands that is sensitive enough to turn a brute machine into a dextrous manipulator.

Designed by researchers in the Harvard Biorobotics Laboratory at SEAS, the sensor, called TakkTile, is intended to put what would normally be a high-end technology within the grasp of commercial inventors, teachers, and robotics enthusiasts.
