For comparison, a decently trained human male can hold approximately 80kg (175lb) per hand (350lb total) fairly easily without any assists such as straps, and without using hook grip. With hook grip or straps, the strength of your back is the limiting factor.
That said, as a first step this is very impressive and very lifelike, too.
The main issue with this is going to be proprioception more than anything - it doesn't seem like you'd be able to do what robots do: rely on position encoders. To make this do something for real it's going to need a way to know its own position, and feel pressure.

- animal531 5y agoI have a really bad back and as a result I can't really exercise. So let's say I can carry 8kg max per hand (1/10th). And yet I'm a fully functional adult human being and can get by perfectly fine in life. So for me from a robotics point of view a much smaller starting range is perfect, once you've built it into a platform you can start optimizing and increasing potential.
- harperlee 5y agoI always joke that if I build a robot I will first target a very old person that can ask for help in a lot of situations. Weak muscles, slow moving, and yet the world will adapt to it, seeing that it is fragile and it needs our help for some things.
- jjk166 5y agoA trained human might be able to deadlift 350lbs under ideal circumstances like being in a gym. No one is capable of lifting and holding that sort of weight for an extended period of time. For an average human under realistic circumstances, lifting 100lbs over your head is a difficult task. Lifting much more than 50 lbs unassisted frequently in a work environment is likely to lead to injury.
