I understand the argument but its honestly ridiculous in my eyes. How about a set of arms that can reach into dishwasher and stack dishes and a washer/dryer to fold laundry... Except even without solving the bipedal movement, that doesn't exist at a consumer price point.
Why are we pretending the hardest version of this is close to existing?
- Schiendelman 3mo agoIt doesn't need to be at a consumer price point first, it needs to replace a human at an existing warehouse or manufacturing role first, and that's achievable in the next two years at this point. When you have arms that can reach into the dishwasher, you're also going to want them to put away your dishes. And so suddenly they need to get up high. And you're not going to have a SECOND set of arms at your washer/dryer to fold laundry, you're just going to buy a second DLC for your existing robot. And it needs to get between those places, so if you have stairs, wheels don't cut it. You need a bipedal robot very quickly.
- jayd16 3mo agoWhy not buy a second set of arms instead of legs or just a set a wheels?
- Schiendelman 3mo agoI feel like if I write two paragraphs, nobody reads the second one...
- rkomorn 3mo agoMaybe they're asking what your argument against buying a second set of arms is, rather than suggesting it as a solution?
- Schiendelman 3mo agoTotally, and they ask why not wheels... I think the key is that none of our actual home use cases can be done with just arms. You don't need your folded clothes sitting in front of your washer and dryer, and a set of arms can't handle folding sheets.
- jayd16 3mo agoWhy not? I would love to have a set of arms that could flip the laundry from the washer to the dryer and then take it out of the dryer and fold it and put it in the basket.
- Schiendelman 3mo agoI understand that particular use case sounds cool! I really do. And then you want them to put away your dishes, and they can't, even though it's just a software update, because they're across the house. And they're BIG, so you don't have room to store two anyway. And they were $20,000, so...
- stickfigure 3mo agoBack around the turn of the (20th) century, electric motors were expensive. It was not uncommon to buy one motor that could do multiple things, like this vacuum/grinder/buffer/blower/pulley: https://www.youtube.com/watch?v=rw_8FWJuSho https://www.youtube.com/watch?v=rw_8FWJuSho If we start making robot arms at scale, they're going to get cheap. I'm also not sure people are really going to want bipedal robots walking around their home, blocking the hallways, recording you in your underwear, etc.
- Schiendelman 3mo agoSure, an electric motor is like 10cm on a side. A set of robot arms that can fold laundry are like a 100cm cube. Most people aren't going to have space for two of them. And the arms need cameras too...
- jayd16 3mo agoUse wheels and buy two if you have to...the Roomba solution. Besides, why do you need to solve stairs the hardest way possible, a fully bipedal robot, before it moves past vapor?
- scheme271 3mo agoStair climbing systems that work using wheels exist. Google stair climbing wheelchairs for a few examples.
- Schiendelman 3mo agoI am familiar, I'm a big fan of Dean Kamen's work. So far, we haven't seen a single wheeled stair climbing vacuum cleaner, even though the original iBOT is 23 years old. That solves the horizontal mobility problem. And then you have cabinets - and wheels don't solve the vertical mobility problem. So then you need a scissor lift on those wheels, or a hydraulic lift. The robotics nerds always end up back at bipedal because it's vastly simpler once you're already solving arms.
- scheme271 3mo agoA scissor lift or some other thing seems a lot simpler than trying to allow for a bipedal robot to knee to reach things close to the ground. Or if legs are the best option, why not a quadruped? Much more stability with a lot of the same advantages.
- Schiendelman 3mo agoI'm curious - have you done any robotics work?
- imtringued 3mo agoOk, so your idea is to sell a machine without software and then hand wave the software part away by saying it will be released at a later date? Sounds like a scam to me. You'll just end up with another AMD situation where the company is only interested in selling the hardware and has zero interest in developing the software, because it costs money and can only ever generate revenue by selling more hardware, which will make the hardware focused company feel vindicated in deciding to not put effort into the software.
- Schiendelman 3mo agoMy idea? No. I'm pointing out that if you release something capable of loading a dishwasher and putting away dishes, it could be as little as a future software improvement to make it do something else.
