Robots Are Coming For Our Jobs. Just Not All Of Them.

There is a lot to be said for replacing certain kinds of jobs with robots. Most people would agree that replacing physical human labor with automation is a good thing. It’s especially good to automate the dangerous kinds of labor like some facets of factory work. What about automation in fields that require more mental labor, where physical strain isn’t the concern? Is replacing humans really the best course of action? A year ago, a video called Humans Need Not Apply set forth an explanation of how robots will inevitably replace us. But that narrative is a tough sell.

Whether it is even possible depends on the job being automated. It also depends on how far we are able to take technology, and the amount of labor we are willing to offload. Automation has been replacing human workers in assembly and manufacturing industries for years. Even with equipment and upkeep expenses, the tireless nature of robotic workers means dramatically lower overhead for businesses.

Many of the current forms of factory automation are rather dumb. When something goes wrong and their task is compromised, they keep chugging away. That costs time and money. But there are companies out there producing robots that are better on many levels.

May Your Robot Overlords Be Cute and Cuddly

baxter-heroIn 2013, Rethink Robotics started filling orders for a new line called Baxter. They are a class of general purpose robot that can be programmed to do many kinds of manual tasks. Baxter bots have vision, and they can learn how to do a job simply by watching. They don’t need to be programmed in the traditional sense.

Baxter even has a face – a screen that shows different expressions depending on his state. When he’s in the midst of a task, his eyes are cast downward. If something goes wrong, he stops what he’s doing. His cartoon face appears sort of shocked, then sad. He goes into safe mode and waits to be fixed.

Hilarious DARPA Robots Falling Video

If you’re worried about Skynet, take a quick gander at the outtakes reel (YouTube, inlined below the break) from the DARPA Robotics Challenge (DRC) and you’ll feel a lot better. The IEEE Spectrum reporters assigned to the DRC took a break from their otherwise serious coverage and made this funny compilation of all the multi-million dollar robotic fails to go along with this article.

robot_fallingIt’s hard not to empathize with the robots, and we’ll admit that we winced a little bit with the first couple falls. (But after three or four, started breaking out in maniacal laughter.)

ATLAS goes for a walk!

Taking Atlas For A Walk

Remember Atlas, the humanoid robot from Boston Dynamics? The company bought by Google, er, owned by Alphabet, and uh, most likely to become Skynet? Well — they’ve just shown us that Atlas can take a light jog through the woods now.

Published on YouTube a few days ago, Boston Dynamics gave a quick presentation on some of the upgrades the company has been working on for their bots. First up is a demonstration of Big Dog’s new appendage… What looks like an elephant trunk with a prosthetic hand on the end. Big Dog can now leave the testing lab any time he wants — door knobs are no longer an obstacle. Considering its been able to traverse extremely rough terrain for years now, this doesn’t bode well…

Atlas on the other hand has also come a long way. From standing on his own for the first time back in 2013, he moved quickly to being hit with medicine balls (and not falling over!) — and now, he can run outside. Luckily they haven’t quite figured out the battery pack solution yet… Video of his outdoor escapades after the break.

Hand Controlled Robot Uses Accelerometer

What do orchestra conductors, wizards, and Leap controller users have in common? They all control things by just waving their hands. [Saddam] must have wanted the same effect, so he created a robot that he controls over wireless using hand gestures.

An accelerometer reads hand motions and sends them via an RF module to an Arduino. This is a bit of a trick, because the device produces an analog value and [Saddam] uses some comparators to digitize the signal for the RF transmitter. There is no Arduino or other CPU on the transmit side (other than whatever is in the RF module).

Hebocons And Why They Matter

Everyone remembers Battlebots, and those of us feeling the pains of nostalgia have tuned into the recent reboot on ABC. As with the golden age of Battlebots, all robot fighting competitions eventually become a war between machines perfectly designed for the task. In the original run of Battlebots, this meant a bracket full of wedge bots, with the very cool robots eliminated year after year.

You don’t watch NASCAR for the race, you watch it for the crashes, and professional robot fighting competitions will always devolve into a few hundred laps of left turns. Fire and sparks are great, but there is a better robot fighting competition, and this time anyone can get in the game without spending years working on a robot.

It’s called Hebocon, and it’s billed as, ‘a sumo wrestling tournament for those who don’t have the technical skills to actually make robots’. The best translation I’ve seen is, ‘shitty robot battles’, and it’s exactly what robot battles should be: technical mastery overcome by guile, and massive upsets through ingenious strategy. You won’t get fire and sparks, but one thing is certain: no robot will make it out of Hebocon fully functional, but that’s only because they weren’t fully functional to begin with.

Lego Exoskeleton Mimics Pacific Rim

Lego Exoskeleton Controls Pacific Rim Robot

As hilariously outrageous as Pacific Rim was, it was still an awesome concept. Giant robot battle suits, duking it out with the aliens. Well, it looks as if it wasn’t quite as far-fetched as we first imagined. Maker [Danny Benedettelli] just released a video of his very own Lego exoskeleton suit that when worn can be used to control a desktop size Cyclops robot. You might remember [Danny] as the author of The Lego Mindstorms EV3 Library,

The Cyclops robot (also his design) was originally built four years ago using Lego Mindstorms NXT system with an Android phone running a custom app. Cyclops has been upgraded a bit for this demonstration. Now it communicates over Bluetooth with an Arduino to [Danny’s] telemetry suit.

Relatively speaking, the system is pretty simple. The Lego exoskeleton has potentiometers on each joint, which map to a degree of freedom for the robot. When one potentiometer spins, the associated robot joint mimics it. Simple, right?

Robot On Rails For Time Lapse Photography

What do you get when you cross a photographer with an Arduino hacker? If the cross in question is [nukevoid], you wind up with a clever camera rail that can smoothly move with both shift and rotation capability. The impressive build uses an Arduino Pro Mini board and two stepper motors. One stepper moves the device on rails using some Delrin pulleys as wheels that roll on an extruded aluminum track. The other stepper rotates the camera platform.

The rotating platform is very cool. It’s a plastic disk with a GT2 motion belt affixed to the edge. The stepper motor has a matching pulley and can rotate the platform easily. The GT2 belt only goes around half of the disk, and presumably the software knows when to stop on either edge based on step counts. There’s even a support to steady the camera’s lens when in operation.
