In spite of the demonstration videos of robots running and jumping and carrying boxes and slowly sorting packages, none of them are anywhere close to being ready to handle construction jobs, or most manufacturing jobs. And, they can't design or make the machines that automate the processes.
It's a billionaire's dream that this is happening now, it's not. One of the major hurdles is power consumption, as we're all seeing while they build out these "data centers". Robots and computers cannot match the efficiency and self-sufficiency of a human. In a picture:
Yep. I work in prosthetics, people tend to overestimate current battery technology and underestimate how much energy it takes to move around a couple hundred pounds.
Even with batteries that cost a small fortune, we haven't been able to create a lower limb powered prosthetic that can keep up with the human body for more than a couple hours.
There's a lot of hype about the humanoid robotics coming out of China, but most everything is just marketing science fiction. Once you factor in the initial cost, power consumption for processing data, multiple batteries per unit, and the massive amount of general maintenance...... It becomes pretty apparent that things aren't going to pan out anytime soon.
I build limbs out of reinforced carbon fiber and titanium and even those acquire a ton of wear in a relatively small amount of time. Any bipedal robot with plastic parts, made to do intensive labour is going to start falling apart almost immediately. The human body takes a ton of damage throughout the day as well, but it's self repairing.
Interesting take. I guess I just realized every video we've ever seen of humanoid robots had been them doing something for a few minutes. But you never hear of one doing anything for days, months or years outside of science fiction.
Bipedal robots are kinda stuck in between a design flaw of what we want robots to look like, what we want robots to do, and what our technology is currently able to do.
Bipedal locomotion is just not the most efficient or simple mode of mobility for things like a flat factory floor, it's really only efficient when you are factoring unleveled ground. We just currently don't have the technology that allows bipedal efficiency across all terrain. That would require a synergistic system of optics and something that mimic propeoception. That's a ton of information being sent from a vast network of sensory input being sorted out by your spine and brain in real time.
Imo robots for a factory floor should be on tracks or wheels. Attempting to design a robot that's good for everything is just going to lead to a robot that is good for nothing. In engineering design should be made to fit a solution, designing for form and then trying to find a solution that form can solve is backwards and typically leads to terrible outcomes.
