1 00:00:00,080 --> 00:00:05,600 I might only be a man. Small, small man. 2 00:00:03,360 --> 00:00:11,120 But with one full day of professional lawnmowing experience, I think I can 3 00:00:07,919 --> 00:00:12,719 kick the ass of that robotic lawnmowing 4 00:00:11,120 --> 00:00:16,440 machine. Yeah, like you can even find its ass, you virgin. 5 00:00:16,880 --> 00:00:23,039 The Luba 2 all-wheel drive 5000X from our sponsor, Mimotion, will turn you to 6 00:00:20,800 --> 00:00:27,920 mulch. Is that a challenge? You bet it is. And here's your first one. Oh, 7 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 8 00:00:30,720 --> 00:00:37,559 the LT logo. Why yes, I think I can. 9 00:00:34,160 --> 00:00:37,559 Let's go. 10 00:00:43,760 --> 00:00:50,719 Lionus is competing against the Motion Aluba 2 5000X all-wheel drive, a 11 00:00:48,239 --> 00:00:56,320 top-of-the-line robotic lawn mower. It's equipped with two powerful cutting discs 12 00:00:52,320 --> 00:00:58,800 that provide a 15.7 in cut width and 165 13 00:00:56,320 --> 00:01:03,600 watts of cutting power. The 12 A battery allows this machine to mow for 13,000 14 00:01:01,280 --> 00:01:07,360 square ft in a single charge. All of these features that Lionus just doesn't 15 00:01:05,519 --> 00:01:10,880 have. The first challenge is all about precision. Lionus will be using his push 16 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 17 00:01:12,720 --> 00:01:17,840 day, but the name of the game here is precision. So, to help him, we provided 18 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 19 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, 20 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 21 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 22 00:01:30,799 --> 00:01:35,600 something refreshing to drink. 23 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 24 00:01:40,720 --> 00:01:46,640 steps. Okay, I've calibrated my steps. 25 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 26 00:01:49,920 --> 00:01:57,200 child. Have fun. Your team has the flag. 27 00:01:53,520 --> 00:01:59,920 Flag dropped. Your team has the flag. 28 00:01:57,200 --> 00:02:03,840 Flag dropped. Oh, I didn't even know this was here. 29 00:02:02,640 --> 00:02:08,720 That would have been helpful, but whatever. I'm doing paces now. The plan 30 00:02:06,240 --> 00:02:14,239 is to map out my landmarks. So, that there is this corner of the circle. Shut 31 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 32 00:02:15,840 --> 00:02:21,200 start with the robot, but I'm worried that once Lionus gets going, he's going 33 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 34 00:02:23,920 --> 00:02:28,959 have something with like a big blade that you're pushing. 35 00:02:27,680 --> 00:02:32,800 I mean, at least I'm not breaking a sweat out here. 36 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 37 00:02:34,959 --> 00:02:40,640 flags marking the eight corners of a 38 00:02:38,319 --> 00:02:44,800 circle. Let's see if I can pull this off. 39 00:02:42,160 --> 00:02:51,280 I mean, if the flag fits, I must have quits, right? 40 00:02:47,920 --> 00:02:56,480 What's he doing? Is he not mowing? Okay, 41 00:02:51,280 --> 00:02:59,599 so then straight, then gentle curve into 42 00:02:56,480 --> 00:03:03,599 this flag, 43 00:02:59,599 --> 00:03:06,159 then steeper curve. What? 44 00:03:03,599 --> 00:03:11,360 How does that make any sense? Oh my god, this is way off. 45 00:03:09,519 --> 00:03:16,480 This isn't even close. Oh crap. How's it going, chief? Great. 46 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 47 00:03:18,000 --> 00:03:23,760 that. I'm just going to relax real quick. 48 00:03:21,680 --> 00:03:28,959 How do you relax quick? It's not really relaxing if you're doing it quickly. 49 00:03:25,599 --> 00:03:31,959 Boom. Power naps. Boom. 50 00:03:28,959 --> 00:03:31,959 Boom. 51 00:03:33,280 --> 00:03:38,680 Oh, shoot. It's not even close. 52 00:03:41,840 --> 00:04:02,739 Oh no. 53 00:04:04,480 --> 00:04:10,560 Definitely getting in my steps. Um, I had this idea where I was going to have 54 00:04:08,560 --> 00:04:14,000 like the whole grid mapped out and everything. I think I give up on that. I 55 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 56 00:04:15,760 --> 00:04:23,600 taking all your flags out. Look, I'm I 57 00:04:19,840 --> 00:04:26,400 tried precision. Now I'm going freeball. 58 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 59 00:04:28,400 --> 00:04:34,320 to wear underwear, so why would it have to freeball? 60 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. 61 00:04:36,160 --> 00:04:42,680 I'm just going for it. 62 00:04:39,680 --> 00:04:42,680 Seriously. 63 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 64 00:04:48,960 --> 00:04:52,199 cut height. 65 00:05:00,320 --> 00:05:07,280 Hey, Sean. How's my circle? Uh, it's um 66 00:05:04,240 --> 00:05:09,520 Shut up. It's very circularly um there's 67 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? 68 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 69 00:05:24,240 --> 00:05:29,840 view. Yeah, that's Hey, there's the part of the circle right there. What the 70 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. 71 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. 72 00:05:35,039 --> 00:05:39,000 Yeah. No. 73 00:05:40,560 --> 00:05:45,360 Also, what might be is that your cut height's not super even. You The blade 74 00:05:43,840 --> 00:05:49,479 might be a little dull. I did bring a file if you want to sharpen it. 75 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. 76 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 77 00:06:10,560 --> 00:06:15,160 side. So, it's going to be kind of eggshaped. 78 00:06:15,199 --> 00:06:23,520 1 2 3 4 5 6 boom. Lionus, it's almost 79 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 80 00:06:25,840 --> 00:06:32,639 both. And I think it's more precise than you as well. 81 00:06:30,319 --> 00:06:36,240 Two and a bit. One of the advantages that the Luba has over Linus' all-wheel 82 00:06:34,720 --> 00:06:39,280 drive. The wheels on this thing can spin across two axis, allowing the mower to 83 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 84 00:06:41,360 --> 00:06:47,919 birectional mower. And the wheels have enough power that this thing can handle 85 00:06:45,520 --> 00:06:51,680 an 80% slope. That's a steep freaking hill. Meanwhile, the design that the 86 00:06:49,680 --> 00:06:55,680 Luba is mowing is shaping up really well thanks to the three key technologies 87 00:06:53,280 --> 00:07:00,000 that work together to deliver centimeter level precision. The first one is GPS. 88 00:06:58,160 --> 00:07:05,280 By using satellites, the lawn mower is able to cover up to 1.25 89 00:07:02,639 --> 00:07:08,479 acres. But you're probably thinking, how is that precise enough to be able to 90 00:07:06,639 --> 00:07:13,199 handle the complex curves of a well manicured lawn? It's not, which is where 91 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 92 00:07:14,479 --> 00:07:20,639 at the side of the road looking like this, then you've seen the godly power 93 00:07:18,240 --> 00:07:24,479 of real-time kinematics or RTK. Basically, by putting a base station in 94 00:07:22,400 --> 00:07:27,680 a known consistent position, we can use it as a means to correct positioning 95 00:07:26,240 --> 00:07:32,000 errors from the satellites that are thousands of meters away. But this 96 00:07:29,759 --> 00:07:35,039 system still requires both the mower and the base station to have a GPS signal. 97 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 98 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 99 00:07:42,319 --> 00:07:48,560 pair of cameras, the Luba 2 gets 3D vision, allowing it to navigate even 100 00:07:46,080 --> 00:07:52,960 more accurately. And it can mow in areas without satellite signals without 101 00:07:50,080 --> 00:07:56,240 getting lost up to 300 m. When the signal is restored, it can use its 102 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 103 00:07:57,919 --> 00:08:03,199 visual fences with no need to lay out magnetic wires or lines for the robot to 104 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 105 00:08:06,479 --> 00:08:12,800 lawn is whose. All of this, plus smart obstacle avoidance, allow the Lubatu to 106 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 107 00:08:14,960 --> 00:08:20,240 that may be on your lawn. At this point, the Lubetu has finished the entire 108 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 109 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 110 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 111 00:08:29,360 --> 00:08:37,839 are. This should give me enough landmarks that I can kind of eyeball the 112 00:08:34,159 --> 00:08:39,519 rest of it, I think. Okay, his robot 113 00:08:37,839 --> 00:08:44,919 might have been done 10 minutes ago, and that might not look like much, but wait 114 00:08:41,279 --> 00:08:44,919 till you see the result. 115 00:08:49,519 --> 00:08:57,920 Is this the L? No, he's putting it upside down. It's 116 00:08:54,720 --> 00:09:02,200 okay. We'll fix it in post. No L's here, 117 00:08:57,920 --> 00:09:02,200 boys. Only W's. 118 00:09:04,480 --> 00:09:09,360 I'm just going to fluff up this area a bit. 119 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 120 00:09:11,680 --> 00:09:14,680 right. 121 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 122 00:09:24,560 --> 00:09:31,760 bad. Took you about an extra 30 minutes, but from here it looks really good. 123 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 124 00:09:33,920 --> 00:09:41,200 also a stupid competition. Who would do this? Uh, you aliens. 125 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 126 00:09:42,959 --> 00:09:49,360 lawn, right? Okay, this could say SOS. I 127 00:09:46,640 --> 00:09:52,800 want a rematch. Just mowing the lawn. Fine. You got a second challenge. Let's 128 00:09:50,959 --> 00:09:58,560 do it. Wow. I really have to be on my tiptoes to Okay, fine. 129 00:09:55,839 --> 00:10:03,680 Oh, man. The camera really doesn't capture it, but it's it's not bad. 130 00:10:01,680 --> 00:10:06,320 It's really not bad. So, you got absolutely destroyed in that first 131 00:10:04,880 --> 00:10:11,839 challenge, but you have a chance to make it up with challenge number two. This is 132 00:10:08,399 --> 00:10:13,279 just a full mo. Okay. Time is what's 133 00:10:11,839 --> 00:10:18,320 most important, but precision also matters. I want to see good lines. Okay. 134 00:10:15,200 --> 00:10:21,200 Oh, yeah. Sweet. 3 2 1 go. No, that's 135 00:10:18,320 --> 00:10:25,480 not I do it. 3 2 1 go. 136 00:10:28,399 --> 00:10:34,560 Go, go, go faster. Dude, all I'm missing 137 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 138 00:10:37,200 --> 00:10:43,279 faster. I've already done as wide a path 139 00:10:41,279 --> 00:10:47,600 here. Except I've done the entire perimeter that wide and it's still just 140 00:10:45,040 --> 00:10:53,440 on the first couple passes. Take that machines making Skynet my Suck 141 00:10:51,680 --> 00:10:58,079 it, Adam. Yeah. Okay. I'm playing Bellatro right now. Admittedly, the 142 00:10:55,760 --> 00:11:03,279 concentric square dio that I have going on here is a little unconventional, 143 00:11:01,519 --> 00:11:07,800 but I think I'm going to lean into it rather than reverse course at this 144 00:11:04,800 --> 00:11:07,800 point. 145 00:11:20,000 --> 00:11:25,200 Oi, do we have another battery for this 146 00:11:23,120 --> 00:11:29,600 thing? Did you run out? Oh, we should have charged that on our break. He 147 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. 148 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 149 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 150 00:11:41,040 --> 00:11:45,360 back to its dock to recharge itself. You 151 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 152 00:11:48,880 --> 00:11:53,680 got something a little bit more, well, normal size, you could always consider 153 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 154 00:11:56,240 --> 00:12:02,480 love eating grass. But Motion promises that this one won't vomit it up on my 155 00:12:00,079 --> 00:12:05,600 carpet after it's done. And they also promise that they're going 156 00:12:04,000 --> 00:12:08,160 to be giving away five of these if you just follow the instructions down in the 157 00:12:07,040 --> 00:12:15,700 description. That's right. You have a chance to win one of five of them. 158 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 159 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 160 00:12:27,600 --> 00:12:36,920 think. Right. Probably less. And I get 161 00:12:31,200 --> 00:12:36,920 to just play Batro Flush five, baby. 162 00:12:45,680 --> 00:12:52,560 Let's go. No way. Yeah. What's up now? 163 00:12:49,519 --> 00:12:54,320 No. But I put in so little effort. I'm 164 00:12:52,560 --> 00:12:59,600 just upset I didn't get to finish Batro in time. Looks good. Good job, Lionus. 165 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? 166 00:13:03,760 --> 00:13:10,320 Cuz we didn't have a tie breaking competition. Here, I have an idea. 167 00:13:07,600 --> 00:13:15,600 Whoever paid for this video is the winner. And that's our sponsor, Motion. 168 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 169 00:13:19,200 --> 00:13:25,680 in a last minute upset. It turns out that Lionus Sebastian is the winner. Way 170 00:13:22,800 --> 00:13:30,000 to go, Lionus Sebastian. Motion paid me. In a last minute last minute upset 171 00:13:27,680 --> 00:13:32,800 upset, it turns out that Motion is again the winner.
