Cartographer – A real-time simultaneous localization and mapping library

SLAM is an essential component of autonomous platforms such as self driving cars, automated forklifts in warehouses, robotic vacuum cleaners, and UAVs.Cartographer builds globally consistent maps in real-time across a broad range of sensor configurations common in academia and industry. The following video is a demonstration of Cartographer’s real-time loop closure:

A detailed description of Cartographer’s 2D algorithms can be found in our ICRA 2016 paper.Thanks to ROS integration and support from external contributors, Cartographer is ready to use on several robot platforms with ROS support:Toyota HSR
TurtleBots
PR2
Revo LDS

At Google, Cartographer has enabled a range of applications from mapping museums and transit hubs to enabling new visualizations of famous buildings.We recognize the value of high quality datasets to the research community. That’s why, thanks to cooperation with the Deutsches Museum (the largest tech museum in the world), we are also releasing three years of LIDAR and IMU data collected using our 2D

Linus Torvalds Says ‘Buggy Crap’ Made It Into Linux 4.8

Two days after Linus Torvalds announced the release of Linux 4.8, he began apologizing for a bug fix gone bad. The Register reports: “I’m really sorry I applied that last series from Andrew just before doing the 4.8 release, because they cause problems, and now it is in 4.8 (and that buggy crap is marked for stable too).” The “crap” in question is an attempt to fix a bug that’s been present in Linux since version 3.15. Torvalds rates the fix for that bug “clearly worse than the bug it tried to fix, since that original bug has never killed my machine!” Torvalds isn’t happy with kernel contributor Andrew Morton, who he says is debugging with a known bad use of BUG_ON(). “I’ve ranted against people using BUG_ON() for debugging in the past. Why the f*ck does this still happen?” Torvalds writes, pointing to a 2002 post to the kernel

Google releases open source ‘Cartographer’

Machine learning and vision are essential technologies for the advancement of robotics. When sensors come together, they can enable a computer or robot to collect data and images in real-time. A good example of this technology in real-world use is the latest Roomba vacuums. As the robot cleans your dirty floor, it is using sensors combined with a camera to map your home. Today, Google releases Cartographer — an open source project that developers can use for many things, such as robots and self-driving cars. “We are happy to announce the open source release of Cartographer, a real-time simultaneous localization… [Continue Reading]

Android 7.1 Nougat’s Changelog Reveals Pixel-Exclusive Features Not Available To Nexus Devices

With the launch of the Google Pixel and Pixel XL yesterday, Google failed to mention the fact that vanilla Android is dead. The Pixel and Pixel XL run Android 7.1 Nougat, custom software made solely for the new Pixel devices and not for past Nexus smartphones. A changelog for Android 7.1 reveals that Nexus smartphones and tablets will not get Pixel-specific features. They won’t get the Pixel Launcher or Google Assistant. BGR reports: Google is trying to set the Pixels apart by giving them special features, and it’s not like that’s an irrational business decision. But the Pixels might change the way Android fans buy devices. Before, you could go for Nexus to get the hottest Android features as soon as Google released Android updates, or you could buy anything else and hope for speedy software upgrade. Now, it seems that you’ll have to buy Pixel to get a full

Drupal 8.2.0 is now available

Drupal 8.2.0, the second minor release of Drupal 8, is now available. With Drupal 8, we made significant changes in our release process, adopting semantic versioning and scheduled feature releases. This allows us to make extensive improvements to Drupal 8 in a timely fashion while still providing backwards compatibility.
What’s new in Drupal 8.2.x?
This new version includes additional experimental modules to place blocks on pages, to edit configuration related to blocks without leaving the page, to create content moderation workflows, and to use date ranges. Several smaller authoring experience, site building, and REST and decoupled site improvements are included as well. (Experimental modules are provided with Drupal core for testing purposes, but are not yet fully supported.)

Dell XPS 13 Developer Edition now available with Ubuntu Linux and Intel Kaby Lake CPU

When you want a laptop running Ubuntu, you can always purchase a Windows machine and replace the operating system. Why bother with that hassle, though? Instead, it is smart to buy a machine pre-loaded with a Linux-based operating from a company like System76. While System76 sells brilliant Ubuntu-powered laptops and desktops, it is not the only game in town. Actually, believe it or not, Dell has long been a proponent of Linux, even before ‘Project Sputnik’. Its Ubuntu-powered XPS 13 Developer Edition laptops have been quite popular, and for good reason — they are built well and are very beautiful. Today, Dell… [Continue Reading]

Today’s another milestone day for Linux

Aug. 25 may be Linux’s official birthday, but Oct. 5 is in many ways the day it began to make a real mark on the world. That’s when Linux creator Linus Torvalds officially released the first Linux kernel into the wild.
“As I mentioned a month(?) ago, I’m working on a free version of a minix-lookalike for AT-386 computers,” Torvalds wrote in a newsgroup post on Oct. 5, 1991. “It has finally reached the stage where it’s even usable (though may not be depending on what you want), and I am willing to put out the sources for wider distribution.”To read this article in full or to leave a comment, please click here
