In the last week, state and federal firefighters have fought more than 270 wildfires in California. Here’s the problem: firefighters are seeing more unauthorized consumer drones flying over active wildfires. Maybe the drone owners don’t know or maybe they don’t care, but temporary flight restrictions are placed over wildfire areas due to the aircraft used to help contain the fires. Aircraft is used to knock down flames and survey the burn area. Some of the drones will get up in the air, and if their drone is in the air, the aircraft actually has to cease its operations.

Senator Dianne Feinstein (D-Calif.) has introduced the Consumer Drone Safety Act that looks to shore up safety features on consumer drones and the federal laws that govern them. This bill has nothing to do with the FAA’s proposed rules on small commercial drones, this is all about hobbyist drones. It’s looking to regulate the maximum height for flight, the weather and time-of-day conditions for flight, and any areas where flights may be prohibited.
If passed, the act would require manufacturers to update existing consumer drones to meet these requirements, potentially through an automatic software update. The bill would require safety features for new consumer drones such as Geo-fencing to govern the altitude and location of flights, collision-avoidance software, and more.

DARPA deliberately degraded communications (low bandwidth, high latency, intermittent connection) during the challenge to truly see how a human-robot team could collaborate in a Fukushima-type disaster. And there was no standard set for how a human-robot interface would work. So, some worked better than others. The winning DRC-Hubo robot used custom software designed by Team KAIST that was engineered to perform in an environment with low bandwidth. It also used the Xenomai real-time operating system for Linux and a customized motion control framework. The second-place finisher, Team IHMC, used a sliding scale of autonomy that allowed a human operator to take control when the robot seemed stumped or if the robot knew it would run into problems.

Rumors have been swirling for some time that GoPro was developing a drone. Well, now it's official. Speaking at the Code Conference, GoPro CEO Nick Woodman announced the company’s plans to come out with a quadcopter in the first half of 2016. Woodman said “the quad is in some ways the ultimate GoPro accessory,” adding that the company is testing software that will wirelessly sync up GoPro footage to the cloud.

Hycopter uses its frame to store energy in the form of hydrogen instead of air. With less lift power required, Hycopter’s fuel cell turns the hydrogen in its frame into electricity to power its rotors. Hycopter can fly for four hours at a time and 2.5 hours when carrying a 2.2-pound payload. "By removing the design silos that typically separate the energy storage component from UAV frame development — we opened up a whole new category in the drone market, in-between battery and combustion engine systems."

The White House was placed on lockdown this afternoon after a man allegedly tried to fly a drone near the building, authorities said. The Secret Service detained and is questioning an individual in connection with a drone flying in Lafayette Park, according to a senior official. President Barack Obama is not currently in the White House and is at Camp David. It’s the second drone incident at the White House in 2015.

According to the filing with the USPTO, the e-commerce giant’s delivery drones will be able to communicate with each other, find the best flight path available, and update the delivery location as a customer changes location. Package delivery locations will be updated as customers move around, so a package can come to you at work or home, depending on where you are when your shipment is ready — including pulling location data from a smartphone. There will also be relay locations, allowing drones to drop off packages for further transport, or to recharge or swap batteries. Amazon even supplies a mockup of what its delivery drone could look like, including eight propellers, two removable power modules and much more.

Working with Massachusetts General Hospital, MIT has developed a computational model that aims to automatically suggest cancer diagnoses by learning from thousands of data points from past pathology reports. The core idea is a technique called Subgraph Augmented Non-negative Tensor Factorization (SANTF). In SANTF, data from 800-plus medical cases are organized as a 3D table where the dimensions correspond to the set of patients, the set of frequent subgraphs, and the collection of words appearing in and near each data element mentioned in the reports. This scheme clusters each of these dimensions simultaneously, using the relationships in each dimension to constrain those in the others. Researchers can then link test results to lymphoma subtypes.

This autonomous Pontiac Trans Sport minivan that drove 3,000 miles was built over about a four-month time frame for under $20,000. We had one computer, the equivalent of a 486DX2, a 640x480 color camera, a GPS receiver, and a fiber-optic gyro. It’s funny to think that we didn’t use the GPS for position, but rather to determine speed. In those days, GPS Selective Availability was still on, meaning you couldn’t get high-accuracy positioning cheaply. And if you could, there were no maps to use it with! But, GPS speed was better than nothing, and it meant we didn’t have to wire anything to the car hardware, so we used it.
