Unitree G1 Humanoid Robot: Overview & Upcoming Teardown

[00:00:00] Speaker 1: Hello everyone it's Armin Foschinovsky with Monro and Associates and today I'm bringing you a humanoid robot. This is a Unitary G1. This is the base version of it. It has about 23 degrees of freedom. All right so these are the actuators you see here that he can move with. It's about a half kilowatt hour battery in its chest, sensor suite in the top, LiDAR, RGB cameras. This model has dummy hands but we have also independently of this teardown purchased some dexterous hands and this is a finger from one of those hands. Maybe you've seen this video on YouTube already. Walking speed of this model is about two meters per second. So you can kind of get a sense of the speed here from walking around. I am remote controlling him right now for this demo but he has some autonomous features as well. So with the LiDAR you can scan the room, set them on patrols. The other versions of this robot that are out there you might have seen them. They do backflips, acrobatics, they run. This is largely the same except for the processor and the hands etc. But to summarize why we have this one here from a sort of broader perspective. Humanoid robotics in some sense are reconfigured electric vehicles. Right, so you have everything in these guys that you find in an electric vehicle. You have actuators, battery system, you have to keep the actuators cool, you have to be ready for scale manufacturing, you have to have the same or similar cost pressures and so with that we're uniquely suited with our 36 years of tear down and costing experience to take a good look at this and really learn how these function from sort of a first principles perspective. And then as we go through we will create a report and also think about how could you construct these systems more cost effectively. Right, so a little bit of overview of this guy like I said it's 23 degrees of freedom. This guy obviously a little bit shorter. I'm on the taller side he's about four foot four, 132 centimeters, 35 kilograms, 75 pounds and actually you know that's nice for developers it's a little bit easier to handle and also less risk if this is going to fall on your, you know, your foot steps on you or you know you have some type of glitch as you're developing your software systems. The battery in here is 9000 milliamp hours. It's a 46, 48 volt system so that translates about to half a kilowatt hour. If you think in EVs right, that might be a little bit more representative or for you to contextualize the battery in there. We haven't torn it off so we don't know what kind of cells are in there yet. We'll find out for you and yeah we'll move them around a little bit. Walking speed of this guy is of this version is about two meters per second. If you go on YouTube, look at Unity G1. This is the model that you see doing backflips, acrobatics, right, running. I think it even participated in the Beijing Humanoid marathon. Certainly the larger version of this has. All right, you probably have seen different people push different robots around and this guy can do it as well. Right, so he has a pretty good balance in there built in. Right, so if you give him a little push, not too hard, but about this, he'll balance. Right, so this robot has position sensors via encoders on all the motors so he knows the state of the entire system at all times and also of course there's accelerometers, g-meters on the robot and it calculates how to recover. Right, so he does it pretty well. We have managed to push him too hard. He doesn't like it. He falls on his face or back or whatever but if you just go like this it works pretty well and it's very fun if you ever come across a robot just give him a push. But yeah, it's a real humanoid robot that has all the core systems of anything you know that that's leading the market and we're tailored down and we'll bring you a series and if you stay tuned you'll learn everything that's in there along with us. Thank you everyone and please like and subscribe. [00:05:28] Speaker ?: so you
