Machine vision and AI enhance 3-D printing

Adding machine vision and artificial intelligence (AI) to 3-D printing allows industrial printers to produce products that have never been printed before.

Using the researchers' path planning algorithm, complex paths that typically take 15 to 30 minutes to specify manually can be generated in just a few seconds, bringing the tool from from source to destination to complete manufacturing tasks without human help.

Technique helps robots find the front door

MIT engineers, along with the Ford Motor Company, have developed a navigation method for robots that enables a robot to use clues in its environment to plan out a route to its destination, which can be described in general semantic terms rather than coordinates on a map.

Self-transforming robot blocks can move and identify each other

A team from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed self-assembling robotic cubes that can climb over and around one another, leap through the air, roll across the ground, and identify each other.

A key to compiling the novel Omnipush dataset was building modular objects (pictured) that enabled the robotic system to capture a vast diversity of pushing behavior. The central pieces contain markers on their centers and points so a motion-detection system can detect their position within a millimeter. Courtesy: Massachusetts Institute of Technology (MIT)

Robots learn the fundamentals of object manipulation and pushing

Researchers at MIT have developed a system where robots “learn” from a dataset called Omnipush that captures how pushed objects move to improve their physical interactions with new objects.

These images show the performance of the 1,550-nanometer optical element. The images are light-intensity profiles of the optical field as it appears approximately 185 micrometers above the surface of the optical element. To the left is a simulated light-intensity profile that predicts how the optical element should perform. Note the focal point of light near the center of the image. To the right, an actual light-intensity profile of the optical element, showing that the device does produce a focal point of light at the predicted location. The researchers designed the element to focus light at eight such points at different distances above the element’s surface. Scale bar is 10 micrometers. Courtesy: Alan Zhan, University of Washington
