Intelligent Robotics Safeguarding

Traditional robot applications limit operator access to hazards through hard-guarding and protective devices that either detect and stop the hazard, or prevent access into the safeguarding space until the hazard no longer exists. The introduction of power- and force-limited robots used in collaborative applications changes this environment. Reduced or nonexistent hard-guarding, along with continuous motion and interaction between the robot and the operator, makes the environment inherently dynamic and uncertain. Methods to reduce risks to a tolerable level include limiting forces and speed, but these measures can yield unacceptable production rates.

Using Sensor Fusion to Analyze Laser Processing in Additive Manufacturing

Sensor: “A device that detects or measures a physical property and records, indicates, or otherwise responds to it.” A sensor is a device that detects a physical quantity and responds by transmitting a signal.

Bringing New Vision to Laser Material Processing Systems

The use of modern laser technology has become standard in industrial manufacturing thanks to its speed, accuracy and effectiveness. Lasers are used to engrave parts, electronic printed circuit boards or chip cards. They perforate packaging; structure semiconductor wafers; drill, cut and weld plastics or metals; and create highly complex structures via 3D printing.

3D Imaging Reveals Sub-surface Battery Flaws

Traditional imaging technologies have been used to investigate overall solar efficiency, but many of the methods only offer surface views. A new – and “exciting” – ultra-fast laser technique developed at the Department of Energy's Lawrence Berkeley National Laboratory provides a deeper look and maps a solar cell in three dimensions.

Autonomous Vehicles Open Up New Roads for LIDAR Growth

Laser range-finding, or LIDAR, is a way of measuring distance, directly analogous to radar except using radiation in the near infrared range of the electromagnetic spectrum rather than the radio waves used in radar. LIDAR techniques are used for a variety of final applications including terrain-mapping for geology, urban planning and archaeology; distance measurement for surveying, golf, hunting, military applications, and docking of large ships; and speed measurement for traffic monitoring and speed limit enforcement.

NASA Tests Lasers’ Ability to Transmit Data from Space

The standard way for spacecraft to communicate with teams on the ground has been to use radio waves. NASA, however, will test the use of lasers to increase data communication rates by as much as 100 times. In a Technology Leaders Q&A, JPL physicist Bill Klipstein explains his role as project manager of NASA's Deep Space Optical Communications (DSOC) mission.

Today's Automobile: Supercomputer on Wheels

With every passing year, it's getting more difficult to recognize the current crop of passenger vehicles as the descendants of Henry Ford's Model T. Those first mass-produced vehicles didn't even include a battery or starting system, relying instead on a hand-cranked engine with a magneto to provide ignition. As recently as 20 years ago, many cars were still essentially mechanical systems supplemented by hydraulic or electrical systems for handling functions like steering, ignition, lights, and audio entertainment.
