Swiss kids programming a Thymio robot

GENEVA â€" Unbeknownst to the general public, an international group of children and teengers, together with a swarm of Swiss-made robots, pulled off a stunning mission to save the future of Mars exploration.

Their heroics took place on the "Campus des Nations," part of the International School of Geneva in the Le Grand-Saconnex area, where we were on hand one afternoon last November as a group of roboticists aged 11 to 15 â€" members of a group called the "Dev Club" â€" helped remotely program robots on Mars and thus save the red planet's international base.

It sometimes happens that great technological achievements have spectacular malfunctions. Take the R45 Martian base, for instance. The generator that powers the base is maintained by hundreds of hamster-size "Thymio" robots. "They are very versatile, quite simple and inexpensive, as adapted to uses in kindergarten schools as to European research projects," says Francesco Mondada, head of the Miniature Mobile Robots Group (MOBOTS), from the Swiss Federal Institute of Technology in Lausanne (SFITL).

But unfortunately, the designers of the international Martian base forgot to program the Swiss-made robots to make repairs in the case of meteorite showers. As it turns out, just such a shower knocked the generator out of commission, threatening the survival of the base unless somehow, someway a collaborative rescue initiative â€" a world first for this age group â€" could be launched to reprogram the robots. Fortunately, the group in Le Grand-Saconnex, working with peers in five other countries (France, Austria, Italy, Russia and South Africa), proved they really do have the right stuff.

Lessons for Mars...and Earth

The resuce mission was make-believe of course: the Martian base is really just a model set up in the SFITL’s Robotic Systems Laboratory; and no meteorite actually fell on it. The Hollywoodesque scenario worked wonders, nevertheless, as a motivating framework for a mission where inter-human cooperation is as important as interaction with machines.

After a bit of hesitation, one boy is appointed "communications officer," in charge of managing contacts with the other teams via an instant messaging service that goes with the broadcasting of a video on YouTube. "Yellow has a connection problem," he says. "Blue has lost control." Thirty second later the robots collide. In reality, the event took place 30 seconds before. The communications delay is the result of the huge distance between here and Mars.

The aim of the mission is of course educational. Francesco Mondada and the “Robotics-Intelligent Robots for Improving the Quality of Life” team from the National Center of Competences in Research (NCCR) are working towards spreading technological education around schools. "This event is proof that, if we give means to pupils, they can produce miracles. Now those means just need to be provided," says Mondada.

The stakes are high. This isn't just about saving the exploration of Mars; it's about giving young people tools they need right here on Earth. "In the way we teach children languages and math, we should also give them the basics that would allow them to handle the technological world around them, not only in a consumerist way, but in a critical and creative way," the roboticist explains. "If we don’t train them, they will be left to serve the sole interests of multinational companies."

A robot with universal appeal

Two years ago, as part of its educational section, NCCR Robotics created Thymio, a small, white object with wheels. It is produced by a non-profit association and was developed according to a model based on total access to information by the public, in open hardware and open software. There are now more than 2,000 Thymios in Swiss and French schools.

The designers, working in collaboration with the Lausanne Cantonal Art School (ECAL), wanted an object that would be neutral from an age point of view â€" so that a four-year-old child can find it interesting, while an academic can use it without the impression of working with an object made for babies â€" and in terms of gender. Gender stereotypes is "very serious" concern, says Mondada.

"We offer courses for primary school teachers," he explains. "The idea is that children should be able to approach technology in a very direct way, at an age where girls are still not excluded in this field. There are operations targeting older children, but it’s too late: choices are already cast in concrete."

Back to Mars and the Campus des Nations. A visitor arriving here by accident couldn’t imagine that these children are carrying out, in such a relaxed atmosphere, an inter-planetary achievement. It is surprising to realize that our host group, supervised by David Shaw and Fabien Bruttin, is calmly completing its task before all the others.

The pupils applaud each other, receive diplomas with the prestigious SFITL logo, talk about one of their local heroes, Arthur Zagaryan, the co-founder of the Dev Club and now a student at the King’s College in London. Meanwhile, two pupils go to another corner of the room, where they set themselves a new mission: program a Thymio for "a disco dance with annoying lights and noises."

Pomp And Pirouettes: When Ballet Stars Bid Farewell

On June 11, the prima ballerina Eleonora Abbagnato bid farewell to the Paris Opera, under the gold roof of the historic Palais Garnier. It's an obligatory passage for Parisian ballet dancers of a certain age, a moment that is often happy, always dreaded and sometimes salutary.

PARIS — With one last look at Chagall's enchanting fresco, at the teachers who watched her grow up, at the stage that saw her blossom, Eleonora Abbagnato took her final bow. Never has a star ballerina's farewell been so dramatic, as her big exit was postponed by three cancellations due to a strike, and then the pandemic.

"I'm always positive, I think that destiny does things well," she says in her dressing room a few days before her "adieu." "I knew this evening would eventually take place!" This artist, who wanted to model her last dance on Le Parc by Angelin Preljocaj, ended up dazzling the crowd in a tribute to Roland Petit, which nicely echoed her career.

"He is someone I knew at the age of 10, so it was important to me to perform a ballet by this choreographer. The last time I danced Young Man was for Nicolas Le Riche's farewell, I was four months pregnant! It all began with Roland, and it all ends with him." The ballerina has lost none of her taste for the stage, but there are traditions that forge an institution: At the age of 42, each Opera dancer must leave the premises with a final au revoir to the public and the company.

"It's probably less painful than in other foreign companies, especially Anglo-Saxon ones, where there is no age limit but you are summoned to be told that you are no longer in the shape you were when you started out," says the former star Agnès Letestu. But how will this particular evening be remembered, as a rite of passage or the beginning of a new life? "The farewell is both a moment of extraordinary love with the hall, the orchestra pit, the backstage area ... and at the same time the turning of a page in the history of this institution. Even if the phoenix always rises from its ashes through the appointment of a new star," says Brigitte Lefèvre, the Paris Opera's dance director from 1995 to 2014.

No faux pas when choosing the last dance

This uniquely talented artist deserves the same exceptional ceremony created for the departure of Elisabeth Platel in 1999 and Carole Arbo two years later, which was televised for the very first time. For these kinds of events, the star's personal life comes into play — family members are present in the room, children occasionally come on stage. A perfectly choreographed protocol is followed to a tee, mixing various speeches with the arrival of the Minister of Culture; sometimes a special distinction from the Order of Arts and Letters is awarded. Moments of grace are sprinkled throughout the evening, such as the improvised dance between Aurélie Dupont — the director of dance at the time — and the departing star Marie-Agnès Gillot. The festivities continue into the night, charged with excitement and emotion.

These farewells are planned two or three years in advance when the time comes for the dance director to curate the future program. Aurélie Dupont, like Brigitte Lefèvre before her, likes to ask the star which ballet they prefer as their parting performance and which partners should accompany them.

These are intense moments sometimes experienced as mourning.

"There are some dancers who don't want to say goodbye because they don't like it, because the program doesn't suit them or because they don't feel fit enough," says Agnès Letestu. "I wanted to leave the Paris Opera with La Dame aux Camélias. I had talked to Brigitte Lefèvre about it. Except my farewell was scheduled before the ballet was programmed, so I had to find another one, but I did not agree. So I proposed to her to come back and dance it one month after I left the company, which was quite unusual."

Among the most requested works are the legendary ballets Giselle and L'Histoire de Manon. "The stars like to start with love stories that end badly. Everyone wants a ballet with real drama, in two or three acts, rather than a little pas de deux," says Aurélie Dupont. Dupont's first choice, La Dame aux Camélias, had already been scheduled two years earlier for the farewell of Agnès Letestu, so she settled on Manon. This work, heavy with meaning, was Dupont's big return to the stage after a serious knee injury in 1998, when she feared she could no longer dance.

Like going to the guillotine

As for the brilliant Karl Paquette, it was with Cinderella — a ballet dear to his heart — that he retired at the Opéra Bastille, Paris' second opera house while many dancers prefer the old charm of the more famous Palais Garnier. "The story is funny, the ballet very narrative — one of the most beautiful successes of Nureyev. I loved the golden costume, the scenic effects, the finale of the grand pas de deux. The strongest moment was my entrance on stage in Act II to great applause, even as the musicians continued to play," he recalls.

These are intense moments sometimes experienced as mourning, like when Marie-Agnès Gillot cried heavily before her final step onto the stage. On that fateful day, Agnès Letestu says she felt a very special sensation, strengthening her senses, from her vision to her hearing. "Everything was multiplied tenfold," says Letestu who, a few months earlier, had the feeling of going to the guillotine. "I was very stressed four months before, I was afraid of hurting myself and not being able to dance, of not being up to it, of not enjoying every moment, of crying," says Aurélie Dupont, whose farewell was finally a calming moment. "I especially remember the applause, people were shouting, standing — it lasted more than 20 minutes. And this love is only for you."

I couldn't let myself be overwhelmed by emotion!

Nicolas Le Riche, now director of the Royal Ballet of Stockholm, evokes a "very strong feeling of corporation, of belonging to an institution that we celebrate at the same time." He was the only artist to bid farewell not to a ballet, but to a "special evening" of total freedom, mixing pieces like L'Après-midi d'un faune by Nijinsky and Béjart's Le Boléro. On stage, tributes were paid in his honor by prestigious guests such as singer Matthieu Chedid and actor Guillaume Gallienne.

"I found this repertoire, which transcended the ages, very moving. I received a magnificent note from Nijinsky's daughter. It's an evening where everyone is allowed to be moved and to live these emotions, except the person who is leaving. I couldn't let myself be overwhelmed by emotion, otherwise, I would have taken a step on stage and collapsed!" he recalls. How long did it take him to prepare such a spectacle? "I feel like answering in the manner of Coco Chanel, who made her hat in two scissor strokes. 'But it only took you two minutes?" says a disappointed customer. 'No, Madam, it took me a whole life," she replies. The same way I drew on all that I lived through," says the dancer.

To each their own swan song

While Laëtitia Pujol hesitated a long time before making her farewell, hoping to leave discreetly, others end up with departure full of pomp and circumstance, sometimes to their surprise. "It's a moment you think about all the time without really thinking about it. I certainly wasn't looking forward to it and wanted something intimate. This was the opposite," says Karl Paquette. "The director of the Paris Opera at the time, Stéphane Lissner, wanted to leave on the symbolic day of December 31. "I was doubly pressured because the farewell was broadcast in the cinema, and each of my movements was immortalized. On the last day, you are in a particular state of conditioning because you are saying goodbye to 25 years of career and nearly 42 years of life. You have to protect yourself."

When the farewell came, it was a relief.

Only Benjamin Pech experienced his farewell, an evening in February 2016, as a liberation. And for good reason: "I had a hip injury in 2014. I was diagnosed with rapid degenerative arthritis. To remedy it, I needed a hip replacement. My farewell was scheduled for 2016, so I decided not to have the surgery and continue until then. For two years, I held on by dancing practically on one leg and had to turn to a repertoire that was no longer athletic but theatrical, with compositional roles that opened up other perspectives. Isn't a dancer above all someone who comes to deeply impact the spectator? When the farewell came, it was a relief," he says.

The star had chosen to dance alongside Sylviane, an 84-year-old spectator and one of his lifelong fans, who was present during rehearsals, but unfortunately became ill on the day of the performance. Pech took his leave on a program that included Le Parc by Preljocaj, the very piece that gave way to his injury: "I have come full circle."

Bidding farewell to the word "adieu"

Shortly after his or her performance, the future retiree must pass on their dressing room to another star, a moment that is "both very sophisticated and archaic. There are the great speeches, which say that this house will always be yours, but in reality, it becomes otherwise," says Brigitte Lefèvre. "You close the door, you leave and it's over," says Eleonora Abbagnato. But how do these artists project themselves into the future? "What is traumatic is that we are heavily drilled since we entered the dance school at 8 years old, with a professional outline where everything is already decided. How can you exist professionally when you have garnered such admiration, even fascination until now? At 42, most people are in the middle of their career, ours is coming to an end," says Benjamin Pech, who has become ballet master at the Opera of Rome, directed by Eleonora Abbagnato.

It is not a door that closes, but rather another door that opens.

While many stars go on to create or run a company, many experience a profound period of confusion. "I was secretly hoping that someone would call me for a position, that I could be of some value, but it didn't happen that way," explains Nicolas Le Riche. "I had already enrolled at Sciences Po for schooling [in management and leadership]. I had to create my own opportunities."

To remedy this uncertainty, Aurélie Dupont now offers support for company members, offering them a skills assessment and training beyond dance. In the future, Nicolas Le Riche would like the word "adieu" to be replaced by the idea of celebration. "It is not a door that closes, but rather another door that opens." Because under the gold of the Palais Garnier, the stars are eternal.
