Some bots were brought out just to watch the dancing.

People lead such different lives! In San Francisco, there are people who test robots by making them fight. Now they have added dance competitions to the mix.

Zara Stone wrote about this recently at the San Francisco Standard: “Cricket just wants to dance.  The $40,000 humanoid robot walked to the center of an octagon cage inside SoMa’s Temple nightclub Thursday night wearing a neon pink wig and struck a pose. A moment later, A-ha’s ‘Take on Me’ filled the air, and Cricket started swiveling its hips, gyrating to the beat.

“Unfortunately for Cricket, it followed Johnny Anthony Lopez, who runs Oakland dance company TURFinc, and seven of his crew. They dropped, popped and locked, performing turf dancing, the Oakland street moves. One dancer, a contortionist, folded to the floor, arms moving like rubber.

“It was a heavy act to follow, and Cricket fully disappointed. It executed three preprogrammed dances. The first was skillful, but the second stalled halfway through. During the third, an engineer had to physically push the robot back into the ring.

“The demonstration was part of a ‘dance-off’ meant to highlight the latest improvements to the robot, a two-year old G1 model from Chinese company Unitree. Programming a humanoid robot to dance used to take engineers weeks, but now the moves can be generated from a video upload. The night was ostensibly both a debut of the robo-dancing and a showcase for the public launch of Studio, a robo-choreography tool. …

“Earlier in the night, two Unitree bots had been part of a fight demonstration, throwing punches in the ring. It wasn’t a one-off. Over the last year humanoid robot fight clubs have become a fixture at techie-oriented San Francisco parties and events.  The crowd was a mix of tech workers wearing hoodies and backpacks, tees with slogans like ‘internet person’ and ‘insert code here.’ …

“ ‘I didn’t even know that dancing was a part of this,’ said Pat Santiago, founder of Accelr8, a hacker house community, who had stuck around. He was initially skeptical of the dance premise. ‘They tend to have a limited repertoire, he said of robots but revised his opinion afterward. ‘I was actually really impressed. … Every time I see a robot dance, it’s 10x the last time.’ 

“The fights followed a predictable rhythm: three 90-second rounds filled with wild swings, body slams, and robots walking into walls while their amateur operators tried desperately to steer them. A human referee counted blows and reset the bots when they faceplanted.

“The seventh bout mixed things up. Vitaly Bulatov, cofounder of Ultimate Bots, faced Trey Roski, cofounder of BattleBots, controlling their respective machines. … Watching two skilled controllers battle demonstrated how important the humans’ roles are. The robots sprung up from the floor, dodged and weaved, and targeted each other with uncanny precision. …

“Tae Marsden, 35, a drag clown from Oakland’s Ruckus Revival, said the fighting entranced her. ‘I grew up with WWE and UFC, and I really appreciated the metal-on-metal action.’ Still, she found the second part of the evening mid. ‘I thought the robot dancing left a lot to be desired.’ 

“Ram Ravi, 35, a machine learning researcher from Oakland, was more forgiving. The dancing was OK, he said, though the fighting was better. He’s not sure he’d go to an event that was just robot dancing. ‘It depends on the progress that’s been made,’ he said.”

I’m on the email list of 13 Forest Gallery in Arlington, Mass. The first time I went there, the owner enlivened his art opening with guest opera singers.

This time, he had a printmaker demonstrate a type of linoleum printing that Picasso dubbed “suicide” printmaking. Others use the word “reduction” instead of “suicide.”

When I tell you how the work is done, you will understand why Picasso felt as he did.

Instead of carving, say, four different blocks for a four-color print, the artist uses only one block. A mistake at one stage can end the whole project.

Lowell resident Susan Jaworski-Stranc has been doing reduction linoleum printmaking for more than 30 years. As the website for 13 Forest explains, “with each layer, you carve more of the block away — so once a layer has been printed and you start carving for the next layer, there’s no going back.”

The artist herself says, “After each successive printing of a color, the surface of the block is reduced while at the same time the printing surface is built up with multi-layered colors. Born from one block of linoleum, my relief prints have the nuance and rich textural surfaces of an oil painting.

“Although Picasso coined this method of working a ‘suicide print,’ I rather think of this printmaking process as emulating the journey of life. While creating my prints, I am never able to re-visit past stages. I can only proceed forward with the acceptance of all good and not so good choices which were mediated and acted upon with the hope and joy of completion.”

On August 13, the gallery was packed as Jaworski-Stranc demonstrated. Many in the audience were experienced printmakers who asked intelligent questions that showed the rest of us what sorts of issues matter to artists.

One person asked if Jaworski-Stranc knew what the picture was supposed to look like in advance, and she explained that she started with a detailed drawing. Another artist wanted to know if the colors of Jaworski-Stranc’s very first reduction print (which she showed us) were what she anticipated.

The artist laughed, holding up that print. “Are you kidding? How would I ever think up a color like this!?”

Clearly, despite all the careful planning that goes into a print, Jaworski-Stranc relishes the beauty of randomness.

Yesterday’s NY Times Dining section had a delightful story about all the food being delivered to Occupy Wall Street. Donations have come from far and wide, and people have self-organized to distribute it and do the washing up. The story is here.

“Requests for food go out on Twitter and various Web sites sympathetic to the protesters. And somehow, in spontaneous waves, day after day, the food pours in. …

“Platters and utensils are washed on site. The soapy runoff slides into a gray-water system that’s said to draw impurities out through a small network of mulch-like filters. …

“Members of the [food] crew sometimes fail to show up in the morning because they were arrested the night before. (Then again, as many a chef will tell you, that happens in a lot of restaurants.)” …

“Telly Liberatos, 29, the owner of Liberatos Pizza on Cedar Street in the Financial District, said he has received orders from places like Germany, France, England, Italy and Greece, as well as every region of the United States.

“ ‘It’s been nonstop,’ he said. ‘The phones don’t stop ringing. People from California order the most at one time.’ Someone from the West Coast had called in the biggest delivery: he wanted 50 pizzas dispatched to the park.”
