85% success and 10% defects: why Amazon robots won’t replace humans yet

Amazon has tested its robots for warehouse logistics and came to an interesting conclusion. Machines are not yet ready to completely replace humans. Two robots participated in a series of experiments — Stow and Pick. Created for placing and selecting goods.

The Stow robot is equipped with a machine vision system, can evaluate free space in cells, and has a special grip with a retractable panel. Its task is to place goods in hanging fabric storage modules. During testing, it processed more than 500000 items. And handled about 85% of them. However, almost 10% of unsuccessful attempts led to damage to goods. Books fell to the floor or pages were crumpled during placement.

224 versus 243 units per hour — humans won. Despite the fact that Stow’s speed almost matched human speed, the amount of defects turned out to be too high for complete process automation.

The Pick robot showed better accuracy. 91% successful item selections over 6 months of testing. But it also has a drawback. In almost 20% of cases, it refused to perform the task, either by not recognizing the object or deciding there was a risk of damaging it.

And now Amazon will work not with manual algorithm tuning, but will train robots to “see and act” like a human.

It turns out they are betting on an “observation learning” approach, reminiscent of human learning. Which will potentially solve the problem of limited adaptability of robots when working with diverse goods.

For 5 years I have been working with machine learning and artificial intelligence. And this field never ceases to amaze, inspire and interest me.

UBTech will send Walker S2 robots to serve on China's border for $37 million

Chinese company UBTech won a contract for $37 million. And will send humanoid robots Walker S2 to serve on China's border with Vietnam. South China Morning Post reports that the robots will interact with tourists and staff, perform logistics operations, inspect cargo and patrol the area. And characteristically — they can independently change their battery.

Anthropic accidentally revealed an internal document about Claude's "soul"

Anthropic accidentally revealed the "soul" of artificial intelligence to a user. And this is not a metaphor. This is a quite specific internal document.

Jensen Huang ordered Nvidia employees to use AI everywhere

Jensen Huang announced total mobilization under the banner of artificial intelligence inside Nvidia. And this is no longer a recommendation. This is a requirement.

AI chatbots generate content that exacerbates eating disorders

A joint study by Stanford University and the Center for Democracy and Technology showed a disturbing picture. Chatbots with artificial intelligence pose a serious risk to people with eating disorders. Scientists warn that neural networks hand out harmful advice about diets. They suggest ways to hide the disorder and generate "inspiring weight loss content" that worsens the problem.

OpenAGI released the Lux model that overtakes Google and OpenAI

Startup OpenAGI released the Lux model for computer control and claims this is a breakthrough. According to benchmarks, the model overtakes analogues from Google, OpenAI and Anthropic by a whole generation. Moreover, it works faster. About 1 second per step instead of 3 seconds for competitors. And 10 times cheaper in cost per processing 1 token.
