SAM Robotic Surrogate Operator
From AkihabaraNews and Robohub:
Conceptually, it’s quite simple: joysticks, knobs, and switches manipulated on a custom radio controller direct the flexing and relaxing of pneumatic “artificial muscles” arranged along “arms and legs” that attach to a vehicle’s pedals and levers. When actuated, the robot replicates a human body’s controlling movements.
Kowa Tech claims the system delivers input strength equal to that of human limbs and an overall operational capability 80% that of in-vehicle operation (with gains expected as the system matures). The 3-piece modular robot is weather and vibration-proof, weighs only about 30 kg (66 lbs.), easily installs in under 30 minutes, and can be removed in half that time. Current prototypes are operable from up to 200m, and commercial models are expected to reach 1 kilometer.
Rounded out with video monitoring for an in-vehicle perspective, in theory ActiveRobo SAM is a near-comprehensive surrogate operator. Most of their demos and testing have thus far been limited to excavator and other heavy equipment work, but the company hopes to eventually make the system adaptable to any vehicle...

Anibit Online Graphical Programmer for the Pololu 3pi Robot
From Anibit:
We have adapted a graphical programming environment for the Arduino known as "Blocklyduino" to be tailored to Pololu's 3Pi Robot Platform. Blocklyduino is itself an adaptation of Blockly, a software package for developers to create graphical programming environments.
All of this is heavily inspired by Scratch and the MIT App inventor. If you are not familiar with those tools and watch to teach kids about programming, you really should check the out.
Graphical Programming is a great introduction to programming for kids. and the Pololu 3Pi is a low cost, ready-made robot that kids love. As part part of our mission at Anibit to inspire and educate about robotics, we felt the need to bring the two together... ( Anibit link )
DARPA Reveals Upgrades To Its Atlas Robot
From DARPA:
The teams using the DARPA-developed Atlas robot got their first look at the newly upgraded system during a technical shakeout the week of January 12th in Waltham, Mass. The upgraded Atlas is 75 percent new—only the lower legs and feet were carried over from the original design. Lighter materials allowed for inclusion of a battery and a new pump system with only a modest increase in overall weight; the upgraded robot is 6-foot-2 (1.88 meters) and weighs 345 pounds (156.5 kilograms).
The most significant changes are to the robot’s power supply and pump. Atlas will now carry an onboard 3.7-kilowatt-hour lithium-ion battery pack, with the potential for one hour of “mixed mission” operation that includes walking, standing, use of tools, and other movements. This will drive a new variable-pressure pump that allows for more efficient operation... ( full details )

NVIDIA Drive PX
From Nvidia's CES press conference:
The DRIVE PX platform is based on the NVIDIA® Tegra® X1 processor, enabling smarter, more sophisticated advanced driver assistance systems (ADAS) and paving the way for the autonomous car.
Tegra X1 delivers an astonishing 1.3 gigapixels/second throughput – enough to handle 12 two-Megapixel cameras at frame rates up to 60 fps for some cameras. It is equipped with 10 GB of DRAM memory and combines surround Computer Vision (CV) technology, extensive deep learning training, and over-the-air updates to transform how cars see, think, and learn.
DEEP LEARNING COMPUTER VISION
Conventional ADAS technology today can detect some objects, do basic classification, alert the driver, and in some cases, stop the vehicle. DRIVE PX takes this to the next level with the ability to differentiate an ambulance from a delivery truck or a parked car from one about to pull into traffic. The system can now inform the driver, not just get their attention with a warning. The car is not just sensing, but interpreting what is taking place around it—an essential capability for auto-piloted driving... ( more info )
VERSABALL Beer Pong Robot
From Empire Robotics:
The VERSABALL is a squishy balloon membrane full of loose sub-millimeter particles. The soft ball gripper easily conforms around a wide range of target object shapes and sizes. Using a process known as “granular jamming”, air is quickly sucked out of the ball, which vacuum-packs the particles and hardens the gripper around the object to hold and lift it. The object releases when the ball is re-inflated. VERSABALL comes in multiple head shapes and sizes that use the same pneumatic base... ( Empire Robotics' site )
Robot Learning Manipulation Action Plans by "Watching" Unconstrained Videos from the World Wide Web
From Yezhou Yang, Yi Li, Cornelia Fermuller and Yiannis Aloimonos:
In order to advance action generation and creation in robots beyond simple learned schemas we need computational tools that allow us to automatically interpret and represent human actions. This paper presents a system that learns manipulation action plans by processing unconstrained videos from the World Wide Web. Its goal is to robustly generate the sequence of atomic actions of seen longer actions in video in order to acquire knowledge for robots. The lower level of the system consists of two convolutional neural network (CNN) based recognition modules, one for classifying the hand grasp type and the other for object recognition. The higher level is a probabilistic manipulation action grammar based parsing module that aims at generating visual sentences for robot manipulation.
The list of the grasping types.
Experiments conducted on a publicly available unconstrained video dataset show that the system is able to learn manipulation actions by “watching” unconstrained videos with high accuracy.... ( article at Kurzweilai.net ) ( original paper )

John Carmack On Modern C++
Winter break homework from John Carmack. Gamasutra reprint article "In-depth: Functional programming in C++":
A large fraction of the flaws in software development are due to programmers not fully understanding all the possible states their code may execute in. In a multithreaded environment, the lack of understanding and the resulting problems are greatly amplified, almost to the point of panic if you are paying attention. Programming in a functional style makes the state presented to your code explicit, which makes it much easier to reason about, and, in a completely pure system, makes thread race conditions impossible...

Modern C++ doesn’t imply necessarly the overuse of templates
Andrei Alexandrescu says about the Modern C++ design:
"Modern C++ Design defines and systematically uses generic components - highly flexible design artifacts that are mixable and matchable to obtain rich behaviors with a small, orthogonal body of code."
Modern C++ has a close relation with generic programming; probably it’s the reason that makes many developers neglect the modern C++ approach. They think that the code will be mostly implemented as templates, which makes the code difficult to read and maintain.
In the SDK, the templates represent only 20% of all types defined and most of them are related to the technical layer... ( full article )
Underactuated Rotor For Simple Micro Air Vehicles
From MODLAB (The modular robotics laboratory at the University of Pennsylvania):
We derive thrust, roll, and pitch authority from a single propeller and single motor through an underactuated mechanism embedded in the rotor itself. This allows new types of conventionally-capable micro air vehicles which only require two motors for practical control. This contrasts with the many servos and linkages of conventional helicopters or the many drive motors found in quadrotors... ( cont'd )

Dynatect Automated Machine Safety Roll-Up Doors
Need to increase safety? Are you using light curtains? Is space a concern?
Dynatect's Gortite® VF Automated Machine Safety Door combines safety technology, speed, and a physical barrier to isolate hazardous operations. Use of a physical barrier with safety sensors can save up to 30 square feet of manufacturing space. Using the ANSI minimum safety distance formula, the Gortite® VF Door limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device. Unlike light curtains, which can't contain process hazards, an automated machine safety door can isolate common workplace debris. This physical barrier is designed to contain process driven hazards such as weld sparks, UV flash, and light debris. Thus, the operator can maintain closer proximity to the work area improving ergonomics and productivity.
