After viewing yours and others 10-10 reporting it looks to me that Tesla basically set up a Tesla "Disney" ride. The bots with their behind the curtain operators, the cyber cabs on their loops, it's all very controlled and basically showed only the surface of the actual developments. That said, it was a fantastic peek at their coming innovations and anyone who doubts that Tesla will deliver on all these innovations are ignoring Tesla's brilliant engineering and production talent, and its deep deep AI infrastructure. I'm just happy that Wall Street still doesn't get it which allows me to continue to scoop up Tesla's stock at ridiculously low valuations. 😊❤

Finally someone noticed and talked about that hand!

[bznsfo]

Should have had the Lex Fridman clip where Musk said 1/2 of engineering is in the hand.

[BrianBellia]

Optimus Gen2's hands seemed perfectly adequate to me.
At this point, Gen3's hand does more than my hands are capable of.

[bluepeed]

The most impressive thing for me was how many of them they had to show off. You can see they are really serious about manufacturing them at scale, I wonder how many they have made in total they could have hundreds already.

[fathom]

Really love you guys. This stuff is so fascinating and you bring it so much to life.

[IntoTheFray.]

Soldiers that use robots get attached to them, just imagine how much more we will be attached to a robot that talks to us, interacts with us, teaches and informs us. Especially if they do it from childhood or even infancy.

[subthousandoaks]

You guys are classic. Two peas in a pod. Love it

[williamwoo]

Thanks Scott Walker and Dr. Know it All

[teslabot]

I cant even do the Clingon thing with my real hands lol

[DThrills]

On October 2nd McDonalds sent a 10.10 tweet. Elon laughed.
I responded to Elon with;
_Will Optimi mingle with the crowd, spewing wit and compliments?_
_(remotely piloted by employees in a back room)_

Here is how I would have handled it differently;
3 people remotely operating each Optimus
Transcriptionist types responses into AI voice replicator speaking in the voice of Morgan Freeman, switching later to Brent Spiner.
2nd person is a hired comedian who crafts witty responses to audience in the area of his bot.
3rd person is accessing Grok, ready to feed answers to any audience questions to the transcriptionist.
High quality audio speaker is incorporated into Optimus.
A simple animated white line appears as his mouth when Optimus speaks
Much more impressive than dancing and handing out little bags
And someday Optimus will do all that independently

Thanks John for sharing. I wonder if they have considered using Muscle Wire or Nitinol? Maybe not a smooth control range or some other reason. The advantage would have been that the wrists would have been far narrower with only an electric harness passing through the carpal tunnel.

[malkum]

Wasn't it said some time ago that the closer you get to human movement, the easier the training becomes. That would explain why more complexity now saves a massive amount of training in the future. Pain now for lots of gain down the road?

[darwinboor]

Rotational actuators can easily compensate for cable stretch and contraction.

[JMeyer-qjpv]

The long tendon approach seems more complex than having the actuators in the hand itself like Figure 02. I guess it will make the hand lighter, but lots of things could go wrong with a bad cable or failed actuator, and then you can't just swap on a new hand. Maybe they really wanted the splayed finger movement and that pushed them to the tendon approach. I'm curious how the grip strength of Figure 02 will compare with the Tesla approach. When the robot uprising comes the grip strength could be decisive!

In England we used to call bike brake cables "Bendix cables".

[stevennelson]

Having had two hand surgeries I now know that the hand is by far the most complex part of the human body; stuffed with tendons, muscles, joints, nerves and blood vessels.

[rwhirsch]

kevlar cord...i had it as emergency spokes for my bike...doesn't stretch.

[PeterTerren]

This microcomplexity does not bode well for lifting 50 pound covered in mud. The attrition due to wear even in optimal circumstances does not fit with being able to do the dirty/dangerous/repetitive requirement.
I work by the keep it simple, stupid.
Have the hand removable at mid forearm level and replaceable with a robust power gripper. Then use body movements to provide more power just like a weight lifter.
Use the power gripper when the hand is in for service or replacement. Make the join at mid forearm level with the least tendon action across it.

[carl-Sp]

The crossover means cable tension isn’t affected by wrist movement. Imagine they were straight, it would tend to lock wrist movement. Apologies if you mentioned this.
