Adstoppi Blog | Amazon is creating detailed 3D models of suburbia to train its new delivery robots

Published by:

When engineers train AI agents to play video games, they often do so at an accelerated rate, having the bot go through hours of human-speed gameplay in a matter of minutes to stress-test its capabilities. Unfortunately, no such shortcut exists when developing AI that controls machines in the real world. You can’t fast-forward reality.

Well, you can if you simulate it, which is what Amazon is doing to test its new Scout delivery robot. Speaking to The Verge, Scout VP Sean Scott explains that the company has created detailed virtual maps of American suburbia to accelerate development of the bot. It’s collected 3D data, real-life textures, and modeled the sidewalk down to the storm drains.

“We can run thousands of deliveries in simulation overnight versus taking a bot outside in the real world,” Scott says. “The bot doesn’t actually know it’s in a simulation. It thinks it’s in the real world, which is pretty cool.”

Think of it like The Matrix but for delivery robots.

Scott adds that he doesn’t know of any other company “talking about this level of fidelity at this scale for this type of training,” and that Amazon’s other training apparatus include an indoor robot park, and special rigs to test the resilience of the bot’s wheels.

Being able to speed up development is important for Amazon, not least of all because it’s a relatively late entrant in the delivery robot game. The company only unveiled its six-wheeled, cooler-sized robot back in January, but a huge range of startups have been building robots in this space for years, testing them in small neighborhoods and closed environments likes offices and campuses.

Of course, if any company is going to make this tech a reality, it’s probably Amazon. Founder and CEO Jeff Bezos boasts of his company’s ability to pour huge financial resources into projects like this, and Amazon loves to experiment with weird delivery options, from drivers that leave packages inside your home to transforming delivery drones.

Scott says the focus in Scout’s development is just the opposite: making sure the robots don’t come across as unusual but as a natural part of the environment. That’s accomplished partly through industrial design, he says, with Scout’s friendly curves, toy-like rubber tires, and chirpy blue paint job giving it a distinctly nonthreatening vibe. “We want the robot to fade into the background,” he says. “We call it ‘design for boring.’”

It also means modeling Scout’s physical behavior. Like all delivery robots, this is a machine that has to work alongside humans, navigating in a way that doesn’t irritate or endanger pedestrians. That means making way for children, pets, prams, and the elderly, but not letting this deference turn into indecisiveness.

It’s a tricky balance to strike, as self-driving cars have demonstrated. Studies show that pedestrians, drivers, and cyclists are likely to take advantage of any overly cautious software design, bullying the autonomous vehicles off the road.

Amazon is confident that it’s on the right path. As an example, Scott proudly shows off two videos of Scout encountering the same neighborhood dog. In the first, the dog is alert and inquisitive, wary of this new arrival in its territory. In the second, it barely pays attention to the bot. “What better way to gauge response than from a pet like this,” he says.

A fast-acting hacker could be able to weaken the encryption of Bluetooth devices and subsequently snoop on communications or send falsified ones to take over a device due to a newly discovered vulnerability in the standard. The vulnerability is pretty clever: instead of directly breaking the encryption, it allows hackers to force a pair of Bluetooth devices to use weaker encryption in the first place, making it far easier to crack. Each time two Bluetooth devices connect, they establish a new encryption key. If an attacker gets in between that setup process, they could potentially trick the two devices into settling on an encryption key with a relatively small number of characters. The attacker would still have to perform a brute-force attack against one of the devices to figure out the...

High cholesterol causes and symptoms

Published by:

Many people are completely unaware that they have high cholesterol, which is why it’s known as the silent killer. “There are no symptoms of high cholesterol,” says Dr. Dermot Neely, who runs a specialist lipid clinic in Newcastle upon Tyne. “The only real symptom is a blocked artery, which causes a stroke or heart attack. In severe cases, you can get cholesterol deposits in the tendons or around the clear part of the eye, but a doctor would rarely notice these during an examination.” So what is it? Cardiovascular diseases are ­responsible for 38% of male and 37% of female deaths before the age of 75, with high cholesterol a serious risk factor. But it’s not all bad. “We all have cholesterol in the blood, and we all need it to be a healthy human,” says Dr. Neely. “It’s...

Bitcoin consumes more energy than the entire nation of Switzerland, according to new estimates published by researchers at the University of Cambridge. An online tool that launched this week called the Cambridge Bitcoin Electricity Consumption Index, or CBECI, estimates how much energy is needed to maintain the Bitcoin network in real time, before using this to calculate its annual energy usage. Currently, the CBECI says the global Bitcoin network is consuming more than seven gigwatts of electricity. Over the course of a year that’s equal to around 64 TWh or terawatt hours of energy consumption. That’s more than the country of Switzerland uses over the same time period (58 TWh per year), but less than Colombia (68 TWh per year). It means Bitcoin accounts for roughly 0.25 percent of...

Twitter expanded on its political ad ban set to roll out next week and provided new guidelines for organizations that advertise on political causes like climate change and abortion. Starting November 22nd, there will be two new advertising polices in place: one for "political content" and one for "cause-based advertising." The political content policy forbids the paid promotion of any content that references candidates, political parties, government officials, legislation, regulation, referendums, or ballot measures. The result effectively bans campaigns and candidates from spending money on Twitter ads. The restriction also bans ads from PACs, super PACs, and 501(c)(4) organizations, which are often used as campaign-adjacent fundraising vehicles in the United States. Twitter's CEO Jack...

Ford is now taking preorders for its first all-electric SUV, the Mustang Mach-E. The company is currently taking $500 deposits for those wishing to reserve their Mustang Mach-E. But as the automaker noted at its launch event in Los Angeles Sunday night, deliveries are still a long way off. You can visit Ford's reservation site for the Mach-E, where you can configure the desired trim, paint color, battery pack, and more. As mentioned previously, Ford is offering a veritable smorgasbord of different versions of this car in an effort to cast as wide a net as possible. The cheapest version is the $43,895 Select (or $44,995 when taking into account delivery costs), which comes standard with 255 horsepower, a 75.7kWh standard range battery pack, and a driving range of 230 miles. But that can...

5G has arrived in the UK, it's fast

Published by:

EE turned on the UK’s first 5G network today, across London, Edinburgh, Cardiff, Belfast, Birmingham, and Manchester. 5G connectivity is now available in limited parts of these cities, more than a month before rival Vodafone plans to launch its own 5G service. I took to the streets of London today to test out 5G, armed with a OnePlus 7 Pro 5G handset. I’m impressed with the early results. While 5G coverage has been extremely limited with Verizon’s 5G network in the US, it’s a whole different story in London. EE has focused its initial coverage on popular tourist destinations across London, including areas like St Paul’s, Covent Garden, Soho, The Strand, Tower Bridge, and London Bridge. I visited a number of different locations today and performed speed tests against both the 4G...

Last month, Valve announced a beta of Steam Remote Play Together, which let you play local multiplayer games over the internet with your friends across Windows, Linux, and macOS computers. Today, Remote Play Together is officially available for everyone, with a what could be a really cool new feature — you can play with your friends using iOS and Android devices as well. According to Valve, the host player just needs to install and start the game, and friends on PC can join in via Steam Remote Play or on mobile with the Steam Chat and Steam Link apps. Only the host needs to actually own the game, which is nice. We haven't been able to test Remote Play Together ourselves with iOS and Android clients yet, so we don't know if network latency might be an issue when you're playing an...

LOS ANGELES Federal investigators on Friday ruled out engine failure as a possible cause of the helicopter crash that killed basketball legend Kobe Bryant, his 13-year-old daughter Gianna, and seven others. The chartered Sikorsky S-76B helicopter that crashed into a hill Jan. 26 had two engines that burned in the aftermath, the National Transportation Safety Board said in an investigative update. "Viewable sections of the engines showed no evidence of an uncontained or catastrophic internal failure," the update states. After the crash, the NTSB has launched a Go Team to the site in an attempt to find the cause. The update reported that a witness to the crash said the area was "surrounded by mist," in the NTSB's paraphrasing, when the Sikorsky was spotted moving fast, descending and...
