Robert Platt from Northwestern has used a new technology created by Edward Adelson from MIT to make a robot that plugs in USBs. This is more difficult than it sounds (unless you’ve had experience with fourth-dimensional USBs, then it’s exactly as difficult as it sounds). If the robot is not pre-programmed, like these on-the-fly USB pluggers, their external sensors must be highly precise—a centimeter off and your drink will get cold without your USB drink warmer. Or worse. Your pet rock may not charge.
In the unspoken scientific agreement to make robots increasingly human, the sensor system relies on vision. One side of the robot’s rubber gripper is coated with metallic paint. The rest of the gripper is surrounded by a translucent box. Each side of the box emits a different-colored light. When the robot grips, the sides light up depending on how the gel inside of the box deformed. By using computer algorithms that monitor the color and intensity of the light, the three-dimensional structure of the gripped surface can be “seen”. This system worked well. The robot was able to find a dangling USB plug, grab it, and plug it into the port.
The more important discovery here is that the robot can insert the USB correctly on the first try. Technology has truly passed our human limitations.
