Yuri 3 rover | The MagPi #82

In honour of the 50th anniversary of the Apollo moon landing, this year’s Pi Wars was space-themed. Visitors to the two-day event — held at the University of Cambridge in March — were lucky enough to witness a number of competitors and demonstration space-themed robots in action.

Yuri 3 rover

Among the most impressive was the Yuri 3 mini Mars rover, which was designed, lovingly crafted, and operated by Airbus engineer John Chinner. Fascinated by Yuri 3’s accuracy, we got John to give us the inside scoop.

Airbus ambassador

John is on the STEM Ambassador team at Airbus and has previously demonstrated its prototype ExoMars rover, Bridget (you can drool over images of this here: magpi.cc/btQnEw), including at the BBC Stargazing Live event in Leicester. Realising the impressive robot’s practical limitations in terms of taking it out and about to schools, John embarked on a smaller but highly faithful, easily transportable Mars rover. His robot-building experience began in his teens with a six-legged robot he took along to his technical engineering apprenticeship interview and had walk along the desk. Job deftly bagged, he’s been building robots ever since.

Inside the Yuri 3 Mars rover

Yuri is a combination of an Actobotics chassis based on one created by Beatty Robotics plus 3D-printed wheels and six 12 V DC brushed gears. Six Hitec servo motors operate the steering, while the entire rover has an original Raspberry Pi B+ at its heart.

Yuri 3 usually runs in ‘tank steer’ mode. Cannily, the positioning of four of its six wheels at the corners means Yuri 3’s wheels can each be turned so that it spins on the spot. It can also ‘crab’ to the side due to its individually steerable wheels.

Servo motors

The part more challenging for home users is the ‘gold thermal blanket’. The blanket ensures that the rover can maintain working temperature in the extreme conditions found on Mars. “I was very fortunate to have a bespoke blanket made by the team who make them for satellites,” says John. “They used it as a training exercise for the apprentices.”

John has made some bookmarks from the leftover thermal material which he gives away to schools to use as prizes.

Rover design

While designing Yuri 3, it probably helped that John was able to sneak peeks of Airbus’s ExoMars prototypes being tested at the firm’s Mars Yard. (He once snuck Yuri 3 onto the yard and gave it a test run, but that’s supposed to be a secret!) Also, says John, “I get to see the actual flight rover in its interplanetary bio clean room”.

His involvement with all things Raspberry Pi came about when he was part of the Astro Pi programme, in which students send code to two Raspberry Pi devices aboard the International Space Station every year. “I did the shock, vibration, and EMC testing on the actual Astro Pi units in Airbus, Portsmouth,” John proudly tells us.

A very British rover

As part of the European Space Agency mission ExoMars, Airbus is building and integrating the rover in Stevenage. “What a fantastic opportunity for exciting outreach,” says John. “After all the fun with Tim Peake’s Principia mission, why not make the next British astronaut a Mars rover? … It is exciting to be able to go and visit Stevenage and see the prototype rovers testing on the Mars Yard.”

The Yuri 3 Mars rover

John also mentions that he’d love to see Yuri 3 put in an appearance at the Raspberry Pi Store; in the meantime, drooling punters will have to build their own Mars rover from similar kit. Or, we’ll just enjoy John’s footage of Yuri 3 in action and perhaps ask very nicely if he’ll bring Yuri along for a demonstration at an event or school near us.

John wrote about the first year of his experience building Yuri 3 on his blog. And you can follow the adventures of Yuri 3 over on Twitter: @Yuri_3_Rover.

Tom Stanton’s trebuchet altitude measurement “golf ball”

YouTuber Tom Stanton built a trebuchet about a year ago. Now, in order to figure out just how high it can toss something, he designed a custom altitude tracking device in the form of an oversize golf ball. 

An Arduino Nano is squeezed inside this sphere, along with a battery, an altimeter, an accelerometer, and even a small servo. The altimeter is used for primary height measurement, while the accelerometer detects launches. A servo then deploys a parachute four seconds later to keep the electronics safe.

As it turns out, the trebuchet is able to fling the ball in the air 60 meters. While impressive, per Stanton’s discussion, it may not be as efficient as you might suspect! Be sure to check out the project in the video below!

Friday Product Post: On the Plus Side

Hello everyone, and welcome back to another Friday Product Post! We have a pretty big week with nine new products to showcase! We kick it all off with the new SAMD51 Thing Plus, a new development board that blows all the others out of the water! Following that, we also have two new Qwiic-enabled boards: a 12-bit ADC board and a pHAT. Programmers should be excited for today too, because we have three new Segger options for you. We have a few more little products as well, but we'll get to those below.

That Thing certainly is a plus!

SparkFun Qwiic 12 Bit ADC - 4 Channel (ADS1015)

In stock DEV-15334

The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C controlled ADC input to your Qwiic enabled project.

$9.95

Sometimes you just need to add more analog inputs to solve a problem. It happens. The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C-controlled ADC input to your Qwiic-enabled project. These channels can be used as single-ended inputs or in pairs for differential inputs. What makes this even more powerful is that it has a programmable gain amplifier that lets you "zoom in" on a very small change in analog voltage (but will still effect your input range and resolution). Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

Why Buy it When You can Build It?

Working at SparkFun has all kinds of perks, many of which appeal to my need to constantly have a project in process. There are multiple 3D printers on each floor of the building; access to an entire warehouse of electronics prototyping parts; shipping that's better than Prime, since I'm already here every day; and a manufacturing shop that essentially serves as a members-only maker space on nights and weekends (provided you put the tools back and clean up afterward).

Recently, I spilled coffee on my keyboard, and now some of the buttons don't work (I brought home the Multimedia Wireless Keyboard that same day, causing minimal delay in access to full-screen typing). While chatting with my team, they floated the idea that I should build a keyboard to replace the damaged one. We had recently discussed how our Cherry MX Breakout and Cherry MX Switch sell really well, but we didn't sell any keycaps. For in-house projects we 3D-print them, but not everyone has access to 3D printers any hour of the day. Sometimes new product decisions are easy, and everyone loves when meetings end early, so if you haven't already noticed, SparkFun now has everything you need build a full mechanical switch: a breakout, a switch, keycaps and a hookup guide.

How to assemble and use the Cherry MX Switch Breakout, allowing you to turn a matrix of mechanical switches into a full-size keyboard!

Now building a custom mechanical keyboard breakout is on my list so I can put the wireless keyboard away for emergency use only – it's too small for my fingers anyway, and has no satisfying clicky sound. This brings to mind a question many makers are familiar with: "Why buy for $X, when you can build it for $10X and a week of your time away from all your other projects in progress, like that half a bike in the garage, the IoT doorbell and the four different prototypes of the SparkFun JetBot AI Kit Powered by NVIDIA Jetson Nano sitting on you desk at work?" Thankfully, the team and I dismissed these thoughts and got down to ordering and soldering. Thank you to those who choose to build incredible projects using SparkFun hardware – we are humbled by your enthusiasm, and we appreciate it!

Why We Can’t Support Modifications to Texas’ Anti-SLAPP Law

Earlier this year, a critical free speech law in Texas came under attack. Texas bill H.B. 2730, as introduced, would have gutted the Texas Citizens Protection Act, or TCPA.

The TCPA has been one of the strongest laws in the nation protecting citizens against SLAPPs. SLAPP is a shorthand way of referring to lawsuits in which the legal claims are just a pretext for silencing or punishing individuals who use their First Amendment rights to speak up on public matters. At EFF, we have supported so-called “anti-SLAPP” laws, like the TCPA, which allow speakers to quickly dismiss frivolous cases against them and often obtain attorney’s fees. 

The original bill, H.B. 2730, would have severely limited the average Texan's ability to use the TCPA and allowed litigious businesses to once again use courts to intimidate their critics. But a broad coalition of groups spoke out against the bill, including journalism associations, environmental groups, and hundreds of Texas-based EFF supporters who emailed their state representatives.

We’re grateful for that vocal opposition, which created momentum for big changes to be made to H.B. 2730. Through your activism, some of the biggest problems have been fixed. But despite those changes, EFF still cannot support the bill, because of two issues that remain.

First, the bill prevents the TCPA from applying when companies sue over alleged trade secret violations, or sue former employees based on non-compete agreements. That leaves big loopholes for parties to allege trade secret or non-compete violations to silence critics or whistleblowers. 

Second, the bill increases the ambiguity over whether TCPA defendants can get their legal fees paid, if they use pro bono or contingent-fee counsel.

We had hoped that lawmakers would address these important concerns before sending the bill to the governor. But that didn’t happen, and we think Texans would be better off if Gov. Greg Abbott vetoes H.B. 2730. 

H.B. 2730: A solution in search of a problem

Since it was passed in 2011, the TCPA has served to protect a wide variety of Texas residents. It has stopped meritless lawsuits, including a case against a Dallas couple who were sued by a pet-sitting company over a negative Yelp review; a lawsuit against individuals who used Facebook to complain about a cosmetic medical treatment; and two lawyers’ attempt to unmask anonymous speakers who posted online comments about Texas’ family court system.

All of which raises the question: if the law was working to protect Texans from vexatious litigation aimed at chilling their First Amendment rights, why was H.B. 2730 needed?

It wasn’t. H.B. 2730 is a solution in search of a problem. Much of the bill was pushed by a group called Texans for Lawsuit Reform, a big-business lobby that published a report on the TCPA in 2018.

In its original form, H.B. 2730 would have severely narrowed what counts as speech about an issue of “public concern” that can be protected by the TCPA, which would have blunted the law’s application to a number of expressive activities. The original bill also would have allowed plaintiffs to unmask online anonymous speakers using a Texas procedure that allows for pre-litigation discovery, by making that process no longer subject to TCPA. This, too, was fixed. 

Protecting anonymous speech online has been a particular concern for EFF. Last year, we filed an amicus brief in support of anonymous Texas speakers who wrote posts on Glassdoor, an employer review site. A business had attempted to use Texas’ pre-litigation discovery process to learn their identities. In that case, the Texas Supreme Court protected the speakers’ identities.

Big improvements, bad exemptions

Strong opposition to H.B. 2730 caused a series of amendments. The amended bill, which passed the Texas State House of Representatives and is now in the Texas State Senate, is a huge improvement over the original proposal. 

The amended bill replaces the narrow definition of “public concern” with a much broader standard. The bill also makes clear the TCPA would protect anonymous speakers subject to the Texas procedure for pre-litigation discovery. And it specifically protects Internet users who face lawsuits for expressing their opinions online about businesses and services.

To all those Texans who sent emails in support of TCPA: thank you for standing up for free speech. You made a terrible bill much better.

Unfortunately, problems still remain with H.B. 2730. Exemptions for cases related to trade-secrets and non-compete agreements mean that when a company sues a current or former employee for allegedly disclosing trade secrets, or violating a non-compete agreement, the worker won’t be able to use the TCPA to dismiss the case. 

But it’s a mistake to assume that things like trade secret accusations can’t be used to stifle speech. The blood-testing company Theranos, whose founder Elizabeth Holmes has now been charged with fraud, used trade secrets threats to try to intimidate both journalists and their sources. Keith Raniere, who is currently on trial for sex-trafficking and extortion charges related to his role as founder of a purported self-help group called NXIVM, used trade secret litigation to sue critics who said NXIVM, a group in which some members were branded, was a cult. 

We’re also concerned that H.B. 2730 will make it harder for ordinary people to get their attorneys’ fees paid. There’s already a split in Texas appeals courts over whether or not the TCPA can be used to repay legal fees in cases where defendants don’t pay attorney’s fees up front or as the case progresses, but instead rely on pro bono or contingent-fee counsel—the types of lawyers used by the great majority of middle-class and low-income folks who get wrapped up in legal disputes.

As Public Citizen’s Paul Levy explains in a detailed blog post, small changes in the wording of H.B. 2730 may actually limit TCPA fee awards to only those defendants who can afford to pay their attorneys’ fees up front. This could lead to a great many speakers caving to demands that they take down their critical but honest posts, rather than vindicating their First Amendment rights. It’s not a small mistake. One of the key components of any anti-SLAPP laws is to encourage attorneys to defend ordinary people who are targeted by SLAPPs, but may not have the money to pay legal bills up front. 

We’re pleased that Texas legislators listened to the public and removed the most drastic problems with H.B. 2730. But at the end of the day, the bill still serves to exempt some of big business’ favorite types of litigation, while making life harder for everyday people who want to exercise their free speech rights. Texas Gov. Greg Abbott should veto the bill.

What You Need to Know About the Latest WhatsApp Vulnerability

If you are one of WhatsApp’s billion-plus users, you may have read that on Monday the company announced that it had found a vulnerability. This vulnerability allowed an attacker to remotely upload malicious code onto a phone by sending packets of data that look like phone calls from a number not in your contacts list. These repeated calls then cause WhatsApp to crash. This is a particularly scary vulnerability because the does not require that the user pick up the phone, click a link, enter their login credentials, or interact in any way.

Fortunately, the company fixed the vulnerability on the server side over the weekend and rolled out a patch for the client side on Monday.

What does that mean for you? First and foremost, it means today is a good day to make sure that you are running the latest version of WhatsApp. Until you update your software, your phone may still be vulnerable to this exploit.

Are you likely to have been targeted by this exploit? Facebook (which owns WhatsApp) has not indicated that they know how many people have been targeted by this vulnerability, but they have attributed its use to an Israeli security company, NSO Group, which has long claimed to be able to install its software by sending a single text message. The exploit market pays top-dollar for “zero-click install” vulnerabilities in the latest versions of popular applications. It is not so remarkable that such capabilities exist, but it is remarkable that WhatsApp’s security team found and patched the vulnerability.
