Tesla's robot folding clothes has just set off a craze, and in just a few days, Musk posted a video of Optimus Prime "walking", which once again attracted a large number of netizens to watch.
I saw that in the huge factory, Optimus Prime took two steps leisurely, and the first thing that is certain is that there is no turn:
The leg movements are more natural than before, and the walking speed is much faster:
You can also see the details of the heel landing first:
In general, the main word "steady", the gait seems to be closer to human:
In just a dozen seconds, the video aroused heated discussions among netizens.
Bojan Tunguz, a machine learning expert at NVIDIA, used Armstrong's famous words when he landed on the moon, saying:
It's a small step for a robot, but it's a giant leap for a "robotkind."
After all, Optimus Prime walked like this stuttering, trembling slow walk before:
A small group of netizens speculated that Optimus Prime was not wearing clothes this time, and it may be doing a hardware test.
However, the focus of many netizens is not here at all (manual dog head), such as:
Musk, can you zoom in on this price tag, I really can't see clearly.
The Evolutionary History of Tesla Robots
At present, Tesla robots have gone through three major evolutionary stages: the prototype Bubmlebee, Optimus-Gen 1, and Optimus-Gen 3.
At Tesla's AI DAY 2022, a prototype without skin was unveiled, and it stumbled at that time:
And Optimus Prime with skin didn't know how to walk on the ground at the time, and was brought to the stage by the staff:
In the end, Optimus Prime went through repeated training, and it took a total of 6 months from taking a slow first step to learning to lift his toes off the ground.
On Tesla's shareholders' day in May last year, the official released a video showing that Optimus Prime could already move down the ground at this time, but very slowly:
Now, according to the official promotional video, Optimus Prime has increased his walking speed by 30% and weighed 10 kilograms.
The feet also feature a hinged structure that mimics the geometry of a human foot.
In addition to walking, you can easily maintain your balance and complete the squat:
The hands and neck have also been upgraded. Among them, the number of hand degrees of freedom has been increased to 11, and a tactile sensor has been added.
The neck has been completely redesigned with an articulated structure and two degrees of freedom.
The remote control stick is exposed again
Some netizens said after watching the video that Optimus Prime walks more like a human, but maybe because:
That's how I walked after my last spinal surgery!
There are also attentive netizens who found that like the previous "folding clothes", Optimus Prime is not completely autonomous in this video, and the remote control stick appears in the video:
But all in all, it still makes some netizens feel the future, belike:
Of course, there are also voices of doubt, after all, this side is still walking, and the Boston Dynamics robot on the other side can parkour a long time ago.
For this point, some netizens speculated that Tesla's focus should be on letting the robot use "brain power", rather than physical strength.
