WEBVTT 00:00:00.080 --> 00:00:05.600 I might only be a man. Small, small man. 00:00:03.360 --> 00:00:11.120 But with one full day of professional lawnmowing experience, I think I can 00:00:07.919 --> 00:00:12.719 kick the ass of that robotic lawnmowing 00:00:11.120 --> 00:00:16.440 machine. Yeah, like you can even find its ass, you virgin. 00:00:16.880 --> 00:00:23.039 The Luba 2 all-wheel drive 5000X from our sponsor, Mimotion, will turn you to 00:00:20.800 --> 00:00:27.920 mulch. Is that a challenge? You bet it is. And here's your first one. Oh, 00:00:25.279 --> 00:00:34.160 great. You can mow a lawn, but can you mow a picture? and a scale drawing of 00:00:30.720 --> 00:00:37.559 the LT logo. Why yes, I think I can. 00:00:34.160 --> 00:00:37.559 Let's go. 00:00:43.760 --> 00:00:50.719 Lionus is competing against the Motion Aluba 2 5000X all-wheel drive, a 00:00:48.239 --> 00:00:56.320 top-of-the-line robotic lawn mower. It's equipped with two powerful cutting discs 00:00:52.320 --> 00:00:58.800 that provide a 15.7 in cut width and 165 00:00:56.320 --> 00:01:03.600 watts of cutting power. The 12 A battery allows this machine to mow for 13,000 00:01:01.280 --> 00:01:07.360 square ft in a single charge. All of these features that Lionus just doesn't 00:01:05.519 --> 00:01:10.880 have. The first challenge is all about precision. Lionus will be using his push 00:01:09.040 --> 00:01:14.560 mower to mow the LT logo into this random dude's lawn. He doesn't have all 00:01:12.720 --> 00:01:17.840 day, but the name of the game here is precision. So, to help him, we provided 00:01:16.159 --> 00:01:20.479 him with these flags and tape. And we've already set a flag in the middle and at 00:01:19.200 --> 00:01:23.840 the edge of the mowing area, so he has an idea of what the radius is. For me, 00:01:22.240 --> 00:01:28.720 this is easy. I just load up the app where I can change all sorts of settings like the cut height, pattern, and mower 00:01:26.880 --> 00:01:34.000 speed. Then I hit this button and we're off to the races. Now I'm going to find 00:01:30.799 --> 00:01:35.600 something refreshing to drink. 00:01:34.000 --> 00:01:44.240 He doesn't even know that we gave him a little measure thing. I just didn't tell him about it. Damn it. Take longer 00:01:40.720 --> 00:01:46.640 steps. Okay, I've calibrated my steps. 00:01:44.240 --> 00:01:53.520 Every step like this is a meter. This is going to be child's play. The play of a 00:01:49.920 --> 00:01:57.200 child. Have fun. Your team has the flag. 00:01:53.520 --> 00:01:59.920 Flag dropped. Your team has the flag. 00:01:57.200 --> 00:02:03.840 Flag dropped. Oh, I didn't even know this was here. 00:02:02.640 --> 00:02:08.720 That would have been helpful, but whatever. I'm doing paces now. The plan 00:02:06.240 --> 00:02:14.239 is to map out my landmarks. So, that there is this corner of the circle. Shut 00:02:11.760 --> 00:02:17.599 up. Circles can have corners. So far, it looks like we're off to a pretty winning 00:02:15.840 --> 00:02:21.200 start with the robot, but I'm worried that once Lionus gets going, he's going 00:02:19.520 --> 00:02:25.120 to have a lot of speed because look at how fast that thing goes versus if you 00:02:23.920 --> 00:02:28.959 have something with like a big blade that you're pushing. 00:02:27.680 --> 00:02:32.800 I mean, at least I'm not breaking a sweat out here. 00:02:31.360 --> 00:02:38.319 Might not look like much, but I've got the concept of a plan here with eight 00:02:34.959 --> 00:02:40.640 flags marking the eight corners of a 00:02:38.319 --> 00:02:44.800 circle. Let's see if I can pull this off. 00:02:42.160 --> 00:02:51.280 I mean, if the flag fits, I must have quits, right? 00:02:47.920 --> 00:02:56.480 What's he doing? Is he not mowing? Okay, 00:02:51.280 --> 00:02:59.599 so then straight, then gentle curve into 00:02:56.480 --> 00:03:03.599 this flag, 00:02:59.599 --> 00:03:06.159 then steeper curve. What? 00:03:03.599 --> 00:03:11.360 How does that make any sense? Oh my god, this is way off. 00:03:09.519 --> 00:03:16.480 This isn't even close. Oh crap. How's it going, chief? Great. 00:03:14.000 --> 00:03:19.360 Never better. That's good. Oh my god. Oh god. Oh, okay. I'm not going to look at 00:03:18.000 --> 00:03:23.760 that. I'm just going to relax real quick. 00:03:21.680 --> 00:03:28.959 How do you relax quick? It's not really relaxing if you're doing it quickly. 00:03:25.599 --> 00:03:31.959 Boom. Power naps. Boom. 00:03:28.959 --> 00:03:31.959 Boom. 00:03:33.280 --> 00:03:38.680 Oh, shoot. It's not even close. 00:03:41.840 --> 00:04:02.739 Oh no. 00:04:04.480 --> 00:04:10.560 Definitely getting in my steps. Um, I had this idea where I was going to have 00:04:08.560 --> 00:04:14.000 like the whole grid mapped out and everything. I think I give up on that. I 00:04:12.480 --> 00:04:19.840 just need to get the edges of my circle marked. What? What are you doing? You're 00:04:15.760 --> 00:04:23.600 taking all your flags out. Look, I'm I 00:04:19.840 --> 00:04:26.400 tried precision. Now I'm going freeball. 00:04:23.600 --> 00:04:29.759 See, that's what a robot can't do. Creativity. I mean, a robot doesn't need 00:04:28.400 --> 00:04:34.320 to wear underwear, so why would it have to freeball? 00:04:32.800 --> 00:04:39.680 That's when you don't wear underwear so your balls. This is how confident I am. 00:04:36.160 --> 00:04:42.680 I'm just going for it. 00:04:39.680 --> 00:04:42.680 Seriously. 00:04:43.840 --> 00:04:52.199 You might have to lift it up. You might have to lift it up a little bit. Lift it up. No, no, no, no, no, no, no. Oh, the 00:04:48.960 --> 00:04:52.199 cut height. 00:05:00.320 --> 00:05:07.280 Hey, Sean. How's my circle? Uh, it's um 00:05:04.240 --> 00:05:09.520 Shut up. It's very circularly um there's 00:05:07.280 --> 00:05:14.360 Wait, is it I don't get it. Is it in there? Wait, no. Is it there? 00:05:19.600 --> 00:05:25.840 There. Can you see it now? Uh, it's uh You got to be kidding me. That's a live 00:05:24.240 --> 00:05:29.840 view. Yeah, that's Hey, there's the part of the circle right there. What the 00:05:27.440 --> 00:05:32.800 hell? Yeah, I can see it. You can see it and they can you see it's right there. 00:05:31.600 --> 00:05:39.000 You're doing great. We'll fix it in post. Yeah. Yeah. Don't worry. Oh, yeah. Maybe bring them close to your screen. 00:05:35.039 --> 00:05:39.000 Yeah. No. 00:05:40.560 --> 00:05:45.360 Also, what might be is that your cut height's not super even. You The blade 00:05:43.840 --> 00:05:49.479 might be a little dull. I did bring a file if you want to sharpen it. 00:05:50.320 --> 00:05:57.000 I I didn't know it was dull. James told me that when I picked it up from him. 00:06:06.639 --> 00:06:12.160 I don't know how it happened, but I'm off by a whole meter from center on this 00:06:10.560 --> 00:06:15.160 side. So, it's going to be kind of eggshaped. 00:06:15.199 --> 00:06:23.520 1 2 3 4 5 6 boom. Lionus, it's almost 00:06:21.120 --> 00:06:27.840 done. It's not about speed, Adam. It's about precision. It's a little bit of 00:06:25.840 --> 00:06:32.639 both. And I think it's more precise than you as well. 00:06:30.319 --> 00:06:36.240 Two and a bit. One of the advantages that the Luba has over Linus' all-wheel 00:06:34.720 --> 00:06:39.280 drive. The wheels on this thing can spin across two axis, allowing the mower to 00:06:38.160 --> 00:06:43.919 turn in place instead of doing that stupid little like wiggle lance that you have to do when you don't have a 00:06:41.360 --> 00:06:47.919 birectional mower. And the wheels have enough power that this thing can handle 00:06:45.520 --> 00:06:51.680 an 80% slope. That's a steep freaking hill. Meanwhile, the design that the 00:06:49.680 --> 00:06:55.680 Luba is mowing is shaping up really well thanks to the three key technologies 00:06:53.280 --> 00:07:00.000 that work together to deliver centimeter level precision. The first one is GPS. 00:06:58.160 --> 00:07:05.280 By using satellites, the lawn mower is able to cover up to 1.25 00:07:02.639 --> 00:07:08.479 acres. But you're probably thinking, how is that precise enough to be able to 00:07:06.639 --> 00:07:13.199 handle the complex curves of a well manicured lawn? It's not, which is where 00:07:11.120 --> 00:07:15.680 the real time kinematics comes in. If you've ever seen a guy in a yellow vest 00:07:14.479 --> 00:07:20.639 at the side of the road looking like this, then you've seen the godly power 00:07:18.240 --> 00:07:24.479 of real-time kinematics or RTK. Basically, by putting a base station in 00:07:22.400 --> 00:07:27.680 a known consistent position, we can use it as a means to correct positioning 00:07:26.240 --> 00:07:32.000 errors from the satellites that are thousands of meters away. But this 00:07:29.759 --> 00:07:35.039 system still requires both the mower and the base station to have a GPS signal. 00:07:33.759 --> 00:07:40.080 So, what happens if the mower goes somewhere where a GPS signal is compromised, like under dense tree 00:07:38.160 --> 00:07:44.319 cover? That's where the Luba 2's Ultra Sense AI vision system comes in. Using a 00:07:42.319 --> 00:07:48.560 pair of cameras, the Luba 2 gets 3D vision, allowing it to navigate even 00:07:46.080 --> 00:07:52.960 more accurately. And it can mow in areas without satellite signals without 00:07:50.080 --> 00:07:56.240 getting lost up to 300 m. When the signal is restored, it can use its 00:07:54.400 --> 00:07:59.599 stored map data to get back on track. And it also allows the robot to set up 00:07:57.919 --> 00:08:03.199 visual fences with no need to lay out magnetic wires or lines for the robot to 00:08:01.759 --> 00:08:08.560 know where it should be. The only reason we set this out was just so that you could see from the sky whose half of the 00:08:06.479 --> 00:08:12.800 lawn is whose. All of this, plus smart obstacle avoidance, allow the Lubatu to 00:08:10.319 --> 00:08:17.120 cut right up to edges within 5 cm of walls and to dodge any sort of obstacles 00:08:14.960 --> 00:08:20.240 that may be on your lawn. At this point, the Lubetu has finished the entire 00:08:18.639 --> 00:08:23.280 design and is now going to go back and forth trying to mow the rest of the 00:08:21.840 --> 00:08:27.919 lawn. I guess we'll let it get a head start on the next challenge. I finalized 00:08:25.360 --> 00:08:31.039 my plan. I'm going around with flags and then I'm marking where all the flags 00:08:29.360 --> 00:08:37.839 are. This should give me enough landmarks that I can kind of eyeball the 00:08:34.159 --> 00:08:39.519 rest of it, I think. Okay, his robot 00:08:37.839 --> 00:08:44.919 might have been done 10 minutes ago, and that might not look like much, but wait 00:08:41.279 --> 00:08:44.919 till you see the result. 00:08:49.519 --> 00:08:57.920 Is this the L? No, he's putting it upside down. It's 00:08:54.720 --> 00:09:02.200 okay. We'll fix it in post. No L's here, 00:08:57.920 --> 00:09:02.200 boys. Only W's. 00:09:04.480 --> 00:09:09.360 I'm just going to fluff up this area a bit. 00:09:07.839 --> 00:09:14.680 Did you accidentally mow too far? That's why uh it's why Jesus made erasers. All 00:09:11.680 --> 00:09:14.680 right. 00:09:19.680 --> 00:09:27.279 I'm actually pretty proud of this. It's not bad. It's not perfect, but it's not 00:09:24.560 --> 00:09:31.760 bad. Took you about an extra 30 minutes, but from here it looks really good. 00:09:29.360 --> 00:09:36.399 Honestly, I'm pretty impressed. It's not like as good as the robots, but it's 00:09:33.920 --> 00:09:41.200 also a stupid competition. Who would do this? Uh, you aliens. 00:09:39.519 --> 00:09:46.640 I mean, maybe you're stuck on a desert island and all you have is a robot and a 00:09:42.959 --> 00:09:49.360 lawn, right? Okay, this could say SOS. I 00:09:46.640 --> 00:09:52.800 want a rematch. Just mowing the lawn. Fine. You got a second challenge. Let's 00:09:50.959 --> 00:09:58.560 do it. Wow. I really have to be on my tiptoes to Okay, fine. 00:09:55.839 --> 00:10:03.680 Oh, man. The camera really doesn't capture it, but it's it's not bad. 00:10:01.680 --> 00:10:06.320 It's really not bad. So, you got absolutely destroyed in that first 00:10:04.880 --> 00:10:11.839 challenge, but you have a chance to make it up with challenge number two. This is 00:10:08.399 --> 00:10:13.279 just a full mo. Okay. Time is what's 00:10:11.839 --> 00:10:18.320 most important, but precision also matters. I want to see good lines. Okay. 00:10:15.200 --> 00:10:21.200 Oh, yeah. Sweet. 3 2 1 go. No, that's 00:10:18.320 --> 00:10:25.480 not I do it. 3 2 1 go. 00:10:28.399 --> 00:10:34.560 Go, go, go faster. Dude, all I'm missing 00:10:32.240 --> 00:10:41.279 is some cake and then this would be a cakewalk. I'm going to be done so much 00:10:37.200 --> 00:10:43.279 faster. I've already done as wide a path 00:10:41.279 --> 00:10:47.600 here. Except I've done the entire perimeter that wide and it's still just 00:10:45.040 --> 00:10:53.440 on the first couple passes. Take that machines making Skynet my Suck 00:10:51.680 --> 00:10:58.079 it, Adam. Yeah. Okay. I'm playing Bellatro right now. Admittedly, the 00:10:55.760 --> 00:11:03.279 concentric square dio that I have going on here is a little unconventional, 00:11:01.519 --> 00:11:07.800 but I think I'm going to lean into it rather than reverse course at this 00:11:04.800 --> 00:11:07.800 point. 00:11:20.000 --> 00:11:25.200 Oi, do we have another battery for this 00:11:23.120 --> 00:11:29.600 thing? Did you run out? Oh, we should have charged that on our break. He 00:11:26.959 --> 00:11:34.320 hasn't even moved. He's not He's not trying to help at all. Look at Get this. 00:11:31.839 --> 00:11:38.000 No, I'm trying to pause my Robo. It's only fair. So, this bad boy just ran out 00:11:36.720 --> 00:11:44.160 of battery. And that's something you don't have to worry about with the Motion because it will automatically go 00:11:41.040 --> 00:11:45.360 back to its dock to recharge itself. You 00:11:44.160 --> 00:11:50.560 don't have to think about it at all. Now, Mimotion doesn't just make lawnmowers for massive lawns. If you've 00:11:48.880 --> 00:11:53.680 got something a little bit more, well, normal size, you could always consider 00:11:52.000 --> 00:11:58.320 their Yuka lineup. It's got the same name as my cat. And just like him, they 00:11:56.240 --> 00:12:02.480 love eating grass. But Motion promises that this one won't vomit it up on my 00:12:00.079 --> 00:12:05.600 carpet after it's done. And they also promise that they're going 00:12:04.000 --> 00:12:08.160 to be giving away five of these if you just follow the instructions down in the 00:12:07.040 --> 00:12:15.700 description. That's right. You have a chance to win one of five of them. 00:12:19.279 --> 00:12:25.600 I got to say, as much as I'm obviously clowning on it in terms of speed, it's 00:12:23.519 --> 00:12:31.200 not by as much as I thought. Like, that should be done in a couple hours, I 00:12:27.600 --> 00:12:36.920 think. Right. Probably less. And I get 00:12:31.200 --> 00:12:36.920 to just play Batro Flush five, baby. 00:12:45.680 --> 00:12:52.560 Let's go. No way. Yeah. What's up now? 00:12:49.519 --> 00:12:54.320 No. But I put in so little effort. I'm 00:12:52.560 --> 00:12:59.600 just upset I didn't get to finish Batro in time. Looks good. Good job, Lionus. 00:12:56.880 --> 00:13:05.120 Aw, thank you. Yeah, that makes this a tie now. That's a problem. Is it though? 00:13:03.760 --> 00:13:10.320 Cuz we didn't have a tie breaking competition. Here, I have an idea. 00:13:07.600 --> 00:13:15.600 Whoever paid for this video is the winner. And that's our sponsor, Motion. 00:13:13.200 --> 00:13:20.959 Way to go, Motion. You're the winner of today's challenge. Yeah, but I paid you 00:13:19.200 --> 00:13:25.680 in a last minute upset. It turns out that Lionus Sebastian is the winner. Way 00:13:22.800 --> 00:13:30.000 to go, Lionus Sebastian. Motion paid me. In a last minute last minute upset 00:13:27.680 --> 00:13:32.800 upset, it turns out that Motion is again the winner.
