Why Repeatability and Accuracy are Different in Motion and Positioning Related Applications

The terms accuracy and repeatability are often used interchangeably. However, accuracy is not possible without repeatability, but repeatability is achievable without accuracy. There are other errors, too, non-linearity errors, and linearity errors caused by thermal effects.

The Future of Unmanned Operations in Harsh Environments Requires Innovation

Hirth Engines Head of International Business Development, Peter Lietz, highlights the importance for engine manufacturers to advance endurance capabilities of unmanned aerial vehicles (UAVs) in extreme terrains.

Researchers create new kind of robot composed of many simple particles with no centralized control or single point of failure

In a new study published today in Nature, researchers at Columbia Engineering and MIT Computer Science & Artificial Intelligence Lab (CSAIL) demonstrate for the first time a way to make a robot composed of many loosely coupled components, or "particles."

DC Motors as Generators

Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive.

A Step Closer to Self-Aware Machines - Columbia engineers create a robot that can imagine itself

Columbia Engineering researchers have made a major advance in robotics by creating a robot that learns what it is, from scratch, with zero prior knowledge of physics, geometry, or motor dynamics.

ASU's Southwest Robotics Symposium previews the new technology guiding the next wave of human-robot interaction

"We can rely on the brain of the human and the muscles, eyes and sense of touch of the robot in places where humans cannot, or should not, be," said Khatib. "For example, we will be able to safely repair underwater structures

Power Density in Robotics

One of the basic requirements for the drives of mobile robots is high power density. For robots, this usually means high torque while taking up the smallest possible space.

"Robotics Skins" turn everyday objects into robots

Developed in the lab of Yale's Rebecca Kramer-Bottiglio, NASA-inspired robotic skins enable users to turn soft objects - a stuffed animal or a foam tube, for instance - into robots.

Festo Underwater robot with unique fin drive

The BionicFinWave uses its two side fins to move along. They are completely cast from silicone and do without struts or other support elements. This makes them extremely flexible and thus able to implement the fluid wave movements of their biological role models

Worcester Polytechnic Institute Professor Developing Origami-Inspired Robots

Professor Cagdas Onal receives $500,000 grant for robots that combine soft and rigid properties; Robots can help in disaster zones or assist those physically challenged with everyday tasks

Rutgers Researchers Create a 3D-Printed Smart Gel That Walks Underwater, Moves Objects

The watery creation could lead to soft robots that mimic sea animals like the octopus, which can walk underwater and bump into things without damaging them.

The Next Big Breakthrough in Robotics

Bill Ibelle for News@NorthEastern: While drones and driverless cars dominate the headlines, another breakthrough-robot dexterity-is likely to have an even greater impact in both business and everyday life

MIT Develops Autonomous "Socially Aware" Robot Using Jackal UGV

The problem of navigating safely among pedestrians poses unique challenges. These include the increased unpredictability of pedestrians actions, as well as the lack of navigation guidelines, such as lane lines.

New technique eases production, customization of soft robotics

Scott Schrage, University of Nebraska-Lincoln via Phys.org: The technique, which creates a stronger chemical bond between silicone and an unprecedented array of plastics, could greatly reduce the time, complexity and expense needed to produce the microfluidic devices.

Autonomous Industrial Drones

The PerceptoCore enables us to have autonomous navigation including autonomous landing and a variety of real time missions done without needing human intervention. In addition, it provides a unique safety layer so even if the communication is cut, the drone still understands

How cameras deliver sharp images despite changing distances

How cameras deliver sharp images despite changing distances

IDS Imaging Development Systems offers a range of models, from a webcam-like camera in industrial quality to a tiny autofocus camera that weighs just12 grams. The 13 MP autofocus camera uEye XC closes the market gap between industrial cameras and webcams. Setting up and operating only requires a cable connection. After that, the autofocus camera immediately delivers high-resolution, detailed images and videos. With the optionally available, quickly exchangeable macro lens, users can easily shorten the minimum object distance of the camera. This makes it also suitable for close-up applications. Focus from a distance of just 10 cm. The uEye XS is even more compact and fits into almost any application with its size of just 26.4 x 23 x 21.7 mm. Thanks to its autofocus and 5 MP CMOS sensor, it delivers consistently sharp images and videos from a distance of just 10 cm. When it comes to image quality, natural color reproduction and harmonious contrast are also decisive factors. IDS has therefore equipped the uEye XS with many other practical automatic features familiar from consumer technology. This includes white balance, exposure and gain. As a result, it delivers the best possible result in every situation.
