Robots With A Delicate Touch Assemble PlayStation 4

August 18, 2020 by Roger Cheng 13 Comments

Sony’s video game division is gearing up for their upcoming PlayStation 5, pushing its predecessor PlayStation 4 off the spotlit pedestal. One effect of this change is Sony ever so slightly relaxing secrecy surrounding the PS4, allowing [Nikkei Asian Review] inside a PlayStation 4 final assembly line.

This article was written to support Sony and PlayStation branding for a general audience, thus technical details are few and far in between. This shouldn’t be a huge surprise given how details of mass production can be a competitive advantage and usually kept as trade secrets by people who knew to keep their mouths shut. Even so, we get a few interesting details accompanied by many quality pictures. Giving us a glimpse into an area that was formerly off-limits to many Sony employees never mind external cameras.

The quoted engineers are proud of their success coaxing robots to assemble soft and flexible objects, and rightly so. Generally speaking robots have a hard time handling non-rigid objects, but this team has found ways to let their robots handle the trickier parts of PS4 assembly. Pick up wiring bundles and flat ribbon cables, then plug them into circuit board connectors with appropriate force. Today’s automated process is the result of a lot of engineers continually evolving and refining the system. The assembly machines are covered with signs of those minds at work. From sharpie markers designating positive and negative travel directions for an axis, to reminders written on Post-It notes, to assembly jig parts showing the distinct layer lines of 3D printing.

We love seeing the result of all that hard work, but lament the many interesting stories still untold. We would have loved a video showing the robots in action. For that, the record holder is still Valve who provided an awesome look at the assembly of the Steam Controller that included a timelapse of the assembly line itself being assembled. If you missed that the first time, around, go watch it right now!

At least we know how to start with the foundations: everything we see on this PS4 assembly line is bolted to an aluminum extrusion big or small. These building blocks are useful whether we are building a personal project or a video console final assembly line, so we’ve looked into how they are made and how to combine them with 3D printing for ultimate versatility.

IRobot Makes Learning Robot More Affordable

August 6, 2020 by Al Williams 10 Comments

When you think of iRobot, you probably think of floor cleaning or military robots. But they also have a set of robots aimed at education. The Root robot — an acquisition the company made in 2019 — originally targeted classrooms and cost about $200 each. A new version costs about $130 and is a better fit for home users.

The original version — Root rt1 — is still available, but the rt0 version has several missing features to hit the desired price. What’s missing? Apparently, the rt1 can stick to a whiteboard using magnets, but that feature is missing on the rt0. There are also no “cliff” sensors or color scanner.

Telepresence Robot Navigates Upgrades

August 6, 2020 by Bryan Cockfield 3 Comments

As time marches on and a good percentage of us are still isolating from society at large, the progress of technology isn’t kept as stagnant. Earlier this year we featured a project about a much-needed small telepresence robot with an exceptionally low barrier for entry, and with the progress of time it has received several upgrades and some crowdfunding, all while preserving its original intent of a simple and easily-operated way of keeping in contact with others.

The new robot is still based on the cardboard design that holds a smartphone and drives it around using a microcontroller platform, but thanks to its small size and low power requirement this seems to suit it nicely. Improvements over the original design include a more robust one-size-fits-all phone mount and a more refined cardboard body. Also, since the small size is a little bit of a downside when navigating anywhere that isn’t a desk or counter, the new version makes it easier to make modifications such as adding a pedestal which can elevate the phone and improve the experience of the remote driver. A number of other optional modifications are possible as well, including a grabbing arm.

While telepresence robots unfortunately are needed now more than ever, we are happy to see people like [Ross] take on projects like this which will hopefully help improve our shared situation by allowing us to have a more involved level of contact with people we would otherwise prefer to see in person. If you’d like to build your own without waiting on the crowdfunding, be sure to check out the original project we featured back in April.

Hackaday Links: August 2, 2020

If you somehow manage to mentally separate yourself from the human tragedy of the COVID-19 pandemic, it really has provided a fascinating glimpse into how our planet operates, and how much impact seven billion people have on it. Latest among these revelations is that the shutdowns had a salubrious effect in at least one unexpected area: solar power. Researchers found that after the Indian government instituted mandatory lockdowns in March, output from solar power installations in Delhi increased by more than eight percent. The cause: the much-diminished smog, which let more sunlight reach solar panels. We’ve seen similar shutdown-related Earth-impact stories, from decreased anthropogenic seismicity to actually being able to see Los Angeles, and find them all delightfully revealing.

Remember Google Glass? It’s hard to forget, what with all the hype leading up to launch and the bitter disappointment of realizing that actually wearing the device wouldn’t go over well in, say, a locker room. That said, the idea of smart glasses had promise, and several startups tried to make a go of combining functionality with less out-there styling that wouldn’t instantly be seen as probable cause for being a creep. One such outfit was North, who made the more-or-less regular looking (if a bit hipsterish) Focals smart glasses. But alas, North was bought out by Google back in June, and as with so many things Google acquires, Focals smart glasses are being turned off. Anyone who bought the $600 specs will reportedly get their money back, but the features of the smart glasses will no longer function. Except, you know, you’ll still be able to look through them.

It looks like someone has finally come up with a pretty good use case for the adorably terrifying robot mini-dogs from Boston Dynamics. Ford Motors has put two of the yellow robots to work in their sprawling Van Dyke Transmission Plant in Michigan. Dubbed Fluffy and Spot (aww), the dogs wander around the plant with a suite of cameras and sensors, digitally mapping the space to prepare for possible future modifications and expansions. The robots can cover a lot of ground during the two hours that their batteries last, and are even said to be able to hitch a ride on the backs of other robots when they’re tuckered out. Scanning projects like these can keep highly trained — and expensive — engineers busy for weeks, so the investment in robots makes sense. And we’re sure there’s totally no way that Ford is using the disarmingly cute robo-pets to keep track of its employees.

We all know that the Linux kernel has some interesting cruft in it, but did you know that it can actually alert you to the fact that your printer is aflame? We didn’t either until Editor-in-Chief Mike Szczys shared this reddit post that details the kernel function lp_check_status and how it assumes the worst if it detects the printer is online but also in “check mode.” The Wikipedia entry on the “lp0 on fire” error message has some interesting history that details how it’s not as implausible as it might seem for a printer, especially one in the early 1970s, to burst into flames under the right conditions. A toner fuser bar running amok on a modern laser printer is one thing, but imagine a printer with a fusing oven running out of control.

And finally, because 2020 is apparently the gift that can’t stop giving, at least in the weirdness department, the US Department of Defense let it slip that the office charged with investigating unidentified aerial phenomena is not quite as disbanded as they once said it was. Reported to have been defunded in 2017, the Advanced Aerospace Threat Identification Program actually appears to live on, as the Unidentified Aerial Phenomena Task Force, operating out of the Office of Naval Intelligence. Their purpose is ostensibly to study things like the Navy videos of high-speed craft out-maneuvering fighter jets, but there are whispers from former members of the task force that “objects of undetermined origin have crashed on earth with materials retrieved for study.” All this could just be a strategic misdirection, of course, but given everything else that has happened this year, we’re prepared to believe just about anything.

VK-01 Is A Bartender You Don’t Need To Tip

[Donald Bell’s] robotic bartender entry into the 2020 Cocktail Robotics Grand Challenge is one of those things that sounds easy until you start getting into the details. After all, how hard is it to dispense some liquids into a glass? Harder than you might think. Sure there are pumps — [Donald] uses peristaltic pumps — but there’s also two Raspberry Pis, an ESP8622, and at least one more microcontroller lurking underneath. You can see a video about the device below.

Even if you don’t want a refreshing libation, you’ll probably like the VK-01’s Bladerunner cyberpunk styling. What we really enjoyed about the post was that it took you through the concept sketches, some of the design trades, and even a cardboard prototype.

Robot, Sudo Fold My Laundry

July 22, 2020 by Al Williams 11 Comments

[Ty Palowski] doesn’t like folding his many shirts. He saw one of those boards on TV that supposedly simplifies folding, but it does require you to manually move the board. That just won’t do, so [Ty] motorized it to create a shirt folding robot.

The board idea is nothing new, and probably many people wouldn’t mind the simple operation required, but what else are you going to do with your 3D printer but make motor mounts for a shirt folding machine? The folding board is, of course, too big for 3D printing so he made that part out of cardboard at first and then what looks like foam board.

A Robotic Stylist For Your Lockdown Lengthened Locks

July 14, 2020 by Dan Maloney 19 Comments

It’s perhaps easy to think that despite the rapid acceleration of technology that there are certain jobs that will never be automated out of existence. Generally the job said to be robot-proof is the one held by the person making the proclamation, we notice. But certainly the job of cutting and styling people’s hair could never be done by a robot, right?

We wouldn’t bet the farm on it, although judging by [Shane Wighton]’s quarantine haircut robot, it’ll be a while before the stylists of the world will be on the dole. Said to have sprung from the need to trim his boyishly long hair, the contraption is an object lesson recreating the subtle manual skills a stylist brings to every head they work on — there’s a reason it takes 1,500 hours or more of training to get a license, after all. [Shane] discovered this early, and realized that exactly replicating the manual dexterity of human hands was a non-starter. His cutting head uses a vacuum to stand the hair upright, 3D-printed fingers to grip a small bundle of hair, and servo-driven scissors to cut it to length. The angle of attack of the scissors can be adjusted through multiple axes, and the entire thing rotates on a hell-no-I’m-not-putting-my-head-in-that-thing mechanism.

To his great credit, [Shane] braved the machine as customer zero, after only a few non-conclusive life-safety tests with a dummy head and wig. We won’t spoil the ending, but suffice it to say that the thing actually worked with no bloodshed and only minimal damage to [Shane]’s style. The long-suffering [Mrs. Wighton], however, was not convinced to take a test drive.

In all seriousness, kudos to [Shane] for attacking such a complex problem. We love what he’s doing with his builds, like his basketball catcher and his robo-golf club, and we’re looking forward to more.
