Offline Robot Programming for Polishing Aircraft Engine Lipskins

In 2020, McStarlite invested in automation by integrating a KUKA robot coupled with Robotmaster offline robot programming (OLP) software, to perform the lipskin polishing application. Lipskins, also known as engine nacelle leading edges, are the aerodynamic structures that make up the leading edge of an airplane engine.

New concrete mold system uses the right amount of concrete and no more

Concrete is the world's most widely consumed material after water, and its production contributes to more than 7% of global CO2 emissions. Achieving global ambitions to limit warming to 1.5ºC will require significant change across the construction sector—not least in how we use concrete.

Top 10 recommendations for a video gamer who you’d like to read (or even just touch) a book

Sure the average video gamer is 34 years old, but the most active group is boys under 18, a group famously resistant to reading. Here is the RTSF Top 10 recommendations of books that have robots plus enough world building to rival Halo or Doom and lots of action or puzzles to solve. What’s even cooler is that you can cleverly use the “Topics” links to work in some STEM talking points by asking things like: do you think it would be easy reprogram cars to hit pedestrians instead of avoiding them? How would you fool a security drone? or Do you think robots should have the same rights as animals? But you may want to read them too, the first six on the list are books that I routinely recommend to general audiences and people tell me how much they loved them.

Head On – The rugby-like game in the book, Hilketa, played with real robots, is the best multiplayer game that never was. And paralyzed people have an advantage! (FYI: a PG-13 discussion of tele-sex through robots). Good for teachable moments about teleoperation.

Robopocalypse– Loved World War Z and read the book? They’ll love this more and it’s largely accurate about robots. Good for teachable moments about robot autonomy.

The Murderbot Diaries (series)- Delightfully snarky point of view of a security robot trying to save clueless scientists from Aliens-like corpos and creatures. Good for teachable moments about software engineering and whether intelligence systems would need a governor to keep them in line.

The Electric State– This is sort of a graphic novel the way Hannah Gadsby is sort of a comedian- it transcends the genre. Neither the full page illustrations nor the accompanying text tell the whole story of the angry teenage girl and her robot trying to outrun the end of the world. Like an escape room, you have to put the text and images together to figure out what is going on. Good for teachable moments about autonomy.

Tales from the Loop– the graphic novels, two in the series, are different from the emo Amazon streaming series. The books are much more suited to a teenage audience who love world building and surprising twists. Good for teachable moments about bounded rationality.

Kill Decision– Scarily realistic description of killer drones, with cool Spec Ops guy who has two ravens with call out to Norse mythology. Good for teachable moments about swarms (aka multi-robot systems).

Robots of Gotham– It’s sort of Game Lit without being based on a video game. Excellent discussion of how computer vision/machine learning works. Good for teachable moments about computer vision and machine learning.

The Andromeda Evolution– Helps if they’ve seen or read the original Andromeda Strain movie, but it can be read as a stand-alone. This commissioned sequel is a worthy addition. Good for teachable moments about drones and teleoperation.

Machinehood – A pro-Robots Rights group is terrorizing the world, nice discussion of ethics amid a lot of action- no boring lectures. Good for teachable moments about robot ethics.

The Themis Files– A earnest girl finds an alien Pacific Rim robot and learns to use it to fight evil giant piloted mecha invaders while shadowy quasi-governmental figures try to uncover its origins. Good for teachable moments about exoskeletons.

A soft magnetic pixel robot that can be programmed to take different shapes

Magnetic soft robots are systems that can change shape or perform different actions when a magnetic field is applied to them. These robots have numerous advantageous characteristics, including a wireless drive, high flexibility and infinite endurance.

Top tweets from the Conference on Robot Learning #CoRL2021

The Conference on Robot Learning (CoRL) is an annual international conference specialised in the intersection of robotics and machine learning. The fifth edition took place last week in London and virtually around the globe. Apart from the novelty of being a hybrid conference, this year the focus was put on openness. OpenReview was used for the peer review process, meaning that the reviewers’ comments and replies from the authors are public, for anyone to see. The research community suggests that open review could encourage mutual trust, respect, and openness to criticism, enable constructive and efficient quality assurance, increase transparency and accountability, facilitate wider, and more inclusive discussion, give reviewers recognition and make reviews citable [1]. You can access all CoRL 2021 papers and their corresponding reviews here. In addition, you may want to listen to all presentations, available in the conference YouTube channel.

In this post we bring you a glimpse of the conference through the most popular tweets written last week. Cool robot demos, short and sweet explanation of papers and award finalists to look forward to next year’s edition in New Zealand. Enjoy!

Robots, robots, robots!

Snake robot turned movie hero

When the Norwegian production company Fantefilm searched the internet to find the coolest underwater robot in the world, they discovered to their surprise that it was being manufactured in Norway. The robot has thus become the first to land a movie role in the film "North Sea," which is premiering now.

Finding inspiration in starfish larva

By Rahel Künzler

Among scientists, there is great interest in tiny machines that are set to revolutionise medicine. These microrobots, often only a fraction of the diameter of a hair, are made to swim through the body to deliver medication to specific areas and perform the smallest surgical procedures.

The designs of these robots are often inspired by natural microorganisms such as bacteria or algae. Now, for the first time, a research group at ETH Zurich has developed a microrobot design inspired by starfish larva, which use ciliary bands on their surface to swim and feed. The ultrasound-​activated synthetic system mimics the natural arrangements of starfish ciliary bands and leverages nonlinear acoustics to replicate the larva’s motion and manipulation techniques.

At first glance, the microrobots bear only scant similarity to starfish larva. In its larval stage, a starfish has a lobed body that measures just a few millimetres across. Meanwhile, the microrobot is a rectangle and ten times smaller, only a quarter of a millimetre across. But the two do share one important feature: a series of fine, movable hairs on the surface, called cilia.

A starfish larva is blanketed with hundreds of thousands of these hairs. Arranged in rows, they beat back and forth in a coordinated fashion, creating eddies in the surrounding water. The relative orientation of two rows determines the end result: Inclining two bands of beating cilia toward each other creates a vortex with a thrust effect, propelling the larva. On the other hand, inclining two bands away from each other creates a vortex that draws liquid in, trapping particles on which the larva feeds.

Artificial swimmers beat faster

These cilia were the key design element for the new microrobot developed by ETH researchers led by Daniel Ahmed, who is a Professor of Acoustic Robotics for life sciences and healthcare. “In the beginning,” Ahmed said, “we simply wanted to test whether we could create vortices similar to those of the starfish larva with rows of cilia inclined toward or away from each other.

To this end, the researchers used photolithography to construct a microrobot with appropriately inclined ciliary bands. They then applied ultrasound waves from an external source to make the cilia oscillate. The synthetic versions beat back and forth more than ten thousand times per second – about a thousand times faster than those of a starfish larva. And as with the larva, these beating cilia can be used to generate a vortex with a suction effect at the front and a vortex with a thrust effect at the rear, the combined effect “rocketing” the robot forward.

Besides swimming, the new microrobot can collect particles and steer them in a predetermined direction. (Video: Cornel Dillinger/ETH Zurich)

In their lab, the researchers showed that the microrobots can swim in a straight line through liquid such as water. Adding tiny plastic beads to the water made it possible to visualize the vortices created by the microrobot. The result is astonishing: both starfish larva and microrobots generate virtually identical flow patterns.

Next, the researchers arranged the ciliary bands so that a suction vortex was positioned next to a thrust vortex, imitating the feeding technique used by starfish larva. This arrangement enabled the robots to collect particles and send them out in a predetermined direction.

Ultrasound offers many advantages

Ahmed is convinced that this new type of microrobot will be ready for use in medicine in the foreseeable future. This is because a system that relies only on ultrasound offers decisive advantages: ultrasound waves are already widely used in imaging, penetrate deep inside the body, and pose no health risks.

“Our vision is to use ultrasound for propulsion, imaging and drug delivery.”

– Daniel Ahmed

The fact that this therapy requires only an ultrasound device makes it cheap, he adds, and hence suitable for use in both developed and developing countries.

Ahmed believes one initial field of application could be the treatment of gastric tumours. Uptake of conventional drugs by diffusion is inefficient, but having microrobots transport a drug specifically to the site of a stomach tumour and then deliver it there might make the drug’s uptake into tumour cells more efficient and reduce side effects.

Sharper images thanks to contrast agents

But before this vision can be realized, a major challenge remains to be overcome: imaging. Steering the tiny machines to the right place requires that a sharp image be generated in real time. The researchers have plans to make the microrobots more visible by incorporating contrast agents such as those already used in medical imaging with ultrasound.

In addition to medical applications, Ahmed anticipates this starfish-​inspired design to have important implications for the manipulation of smallest liquid volumes in research and in industry. Bands of beating cilia could execute tasks such as mixing, pumping and particle trapping.
