BOSTON (AFP) – They can mix cocktails, run marathons and fold laundry. But humanoid robots are still a long way from doing lots of different jobs on command, whatever the marketing says._x000D_

The gap was easy to spot at the Robotics Summit in Boston in late May. The glossy brochures promised one thing. The people who actually build the machines said another._x000D_

Elon Musk loves to show off his Optimus prototype, recently filmed jogging in short strides. Figure 03, a third-generation robot developed by Figure AI, can tidy and clean a living room by itself._x000D_

China’s AgiBot and Matrix Robotics say their robots can greet visitors, serve coffee and give them a tour, a little like C-3PO from “Star Wars.”_x000D_

The reality is more modest._x000D_

“Most of the humanoids you see are being teleoperated, or they’ve got very specific paths and chores that they do,” said Chris Matthieu of startup RealSense, which makes cameras for robots._x000D_

In other words, many are either run by a human with a remote control or stuck doing one narrow task._x000D_

Take Neo, the robot that 1X launched with great fanfare last October. It was billed as “the world’s first consumer-ready humanoid robot designed to transform life at home” – but was actually steered by a person off to the side._x000D_

Progress is real, though, and artificial intelligence is driving it. “I think AI has extremely accelerated that growth,” said William Okazaki of sensor maker Renesas._x000D_

One big hurdle is the hands. Long the holy grail of robotics, they are getting close: robots can now grip with a delicate touch, and some sensors can even tell when they are touching human skin._x000D_
_x000D_
Much of this comes from a new kind of AI known as a VLA model, short for vision-language-action. It blends written instructions with what a camera sees in real time, so the robot can link what it is looking at to what it should do._x000D_
_x000D_
There is also the “world model” – an AI that learns from vast amounts of images and video until it can predict what will happen next in the real world, such as how an object will shift when it is squeezed._x000D_

But an android that can do a bit of everything is still years off._x000D_

“For general purpose robots, it will take longer,” said Daniel Fan of Innodisk, which makes parts for robots._x000D_

Plenty of humanoids are already out in the world – Boston Dynamics’ Atlas at Hyundai, Hexagon Robotics’ AEON at a BMW site – but these are trials, not final products._x000D_

“Until you actually get the robot actually trying to do the thing you think it can do, you don’t really know,” said Charlie Kemp of Hello Robot, which sells robots for people with limited mobility._x000D_

Running fully on their own, at scale, is not yet possible, “because there is not enough data,” said Xinrui Bi of AgiBot._x000D_

To gather it, companies are setting up cameras everywhere to record human movement – from people cooking at home to workers in a textile workshop in India._x000D_

The stakes are higher than for a chatbot like ChatGPT. A robot acts in the physical world, so its mistakes can hurt someone._x000D_
_x000D_
“If you want to move into a more social domain, it really has to be safe for the users around the robot,” said Valentino Fagard of Japan’s XELA Robotics, which works on giving robots a sense of touch._x000D_
_x000D_
Engineers can set limits – telling the machines not to grip too hard, or not to get too close to a person. But there is a catch. Like chatbots, these AI systems don’t always behave the same way twice, which makes them hard to predict._x000D_
_x000D_
“The issue with, call it the world model, or the end-to-end VLA, is they’re non-deterministic, they’re a black box,” said John Black of Brain Corp, whose robots stick to a very specific task, like cleaning floors or checking store shelves._x000D_
_x000D_
“They’re nowhere close to reaching the safety levels required,” he said, because even the people who build these systems can not fully see why they do what they do.
