I need to be watered and fed regularly too. 383 00:21:02,887 --> 00:21:04,431 That sounded better in my head. 384 00:21:04,514 --> 00:21:08,059 My mum doesn’t have time for that. Remember what she said? 385 00:21:08,143 --> 00:21:12,314 Oh yeah. Okay. Well, now that we know how to keep a garden healthy, 386 00:21:12,397 --> 00:21:15,608 we need to find a way to help her take care of it that’s easy. 387 00:21:15,692 --> 00:21:16,985 Let’s brainstorm. 388 00:21:17,068 --> 00:21:24,034 What if we create a new type of plant that never needs food, water, or sunshine? 389 00:21:24,117 --> 00:21:26,161 She wouldn’t have to do anything. 390 00:21:26,244 --> 00:21:29,456 But what if we accidentally make zombie plants? 391 00:21:29,539 --> 00:21:33,918 I’d love that, but Iggy’s mum might not. 392 00:21:34,002 --> 00:21:36,880 Neither would Iggy’s mum’s son, me! 393 00:21:36,963 --> 00:21:40,467 Is there maybe a less zombie-ish idea? 394 00:21:40,550 --> 00:21:44,262 I’ve got one. We could ask garden gnomes to take care of the plants. 395 00:21:44,346 --> 00:21:46,097 They eat a lot though. 396 00:21:46,181 --> 00:21:50,101 And my mum has enough cooking to do for the café and me 397 00:21:50,185 --> 00:21:51,936 without also having to feed gnomes. 398 00:21:52,020 --> 00:21:54,397 She needs something really easy. 399 00:21:54,481 --> 00:21:55,774 Like a magic word? 400 00:21:55,857 --> 00:21:56,900 Or a button? 401 00:21:56,983 --> 00:22:01,946 Wait. Iggy’s mum said she wishes she could press a button to take care of her garden. 402 00:22:02,030 --> 00:22:06,534 So maybe we could build something that waters and fertilises the plants, 403 00:22:06,618 --> 00:22:08,703 with a button that controls it all. 404 00:22:08,787 --> 00:22:10,163 Okay, it’s ready. 405 00:22:10,246 --> 00:22:12,999 Iggy, that’s a plant-astic design. I’ll build it. 406 00:22:24,928 --> 00:22:26,805 And done. 407 00:22:26,888 --> 00:22:29,391 Whoa! What is that thingamyjig? 408 00:22:29,474 --> 00:22:31,601 It’s called the Green Thumbinator. 409 00:22:31,684 --> 00:22:34,270 It waters and fertilises the plants for you. 410 00:22:34,354 --> 00:22:37,357 And to turn it on, you just have to press this button. 411 00:22:43,238 --> 00:22:45,031 Now that I have time for. 412 00:22:45,115 --> 00:22:47,826 Thanks to you three, I finally have green fingers 413 00:22:47,909 --> 00:22:49,119 and a green garden. 414 00:22:49,202 --> 00:22:50,829 Fantastic! 415 00:22:51,913 --> 00:22:55,041 This is the best garden party I’ve ever been to. 416 00:22:55,917 --> 00:22:58,795 And this is the best strawberry smoothie I’ve ever had. 417 00:22:58,878 --> 00:23:02,257 Made with fresh strawberries from my beautiful, healthy garden. 418 00:23:02,340 --> 00:23:06,928 And I’m working on a new dessert menu. Maybe strawberry shortcake? 419 00:23:07,011 --> 00:23:08,179 -Yum! -Yes! 420 00:23:08,263 --> 00:23:09,264 -Hey, kiddo. -Dad! 421 00:23:09,347 --> 00:23:12,475 Just dropping off your sketchbook.

Maybe I need gardening tips from you three. 424 00:23:19,732 --> 00:23:22,986 I’ve got the best tip. You’ve just gotta make the plants laugh. 425 00:23:23,069 --> 00:23:25,947 What do you get when Bigfoot walks through your garden? 426 00:23:26,781 --> 00:23:28,908 Stumped? Get it? Like “stomped”? 427 00:23:28,992 --> 00:23:30,034 Good guess. 428 00:23:30,118 --> 00:23:31,202 Squash! 429 00:23:31,286 --> 00:23:36,332 You know, ’cause Bigfoot’s big feet would squash everything. 430 00:23:37,625 --> 00:23:38,877 -Nice! -I get it. 431 00:23:42,630 --> 00:23:46,759 I have an idea. Let’s meet another scientist. Come on. 432 00:23:52,015 --> 00:23:55,685 Hey, my name is Rory Aronson and I’m a robotics engineer, 433 00:23:55,768 --> 00:23:59,772 and today I’m gonna show you how I take care of my garden with my farming robot. 434 00:24:04,819 --> 00:24:06,279 This is the FarmBot. 435 00:24:06,362 --> 00:24:08,156 FarmBot plants seeds, 436 00:24:08,239 --> 00:24:10,575 waters, takes photos, 437 00:24:10,658 --> 00:24:11,993 and removes weeds, 438 00:24:12,076 --> 00:24:14,829 to take care of your garden and grow plants 439 00:24:14,913 --> 00:24:17,790 so you can have fresh veggies in your backyard. 440 00:24:17,874 --> 00:24:20,793 So one of our FarmBots is at NASA. 441 00:24:20,877 --> 00:24:23,129 They’re using it to do research to figure out 442 00:24:23,213 --> 00:24:25,882 how are we gonna grow food in space? 443 00:24:25,965 --> 00:24:29,511 What they wanna do is be able to send astronauts to Mars 444 00:24:29,594 --> 00:24:33,223 and then grow food for them so that they can eat and survive 445 00:24:33,306 --> 00:24:36,059 without taking up too much of the astronauts’ time. 446 00:24:36,142 --> 00:24:38,853 In here is the brain of the FarmBot. 447 00:24:38,937 --> 00:24:41,523 That’s a little computer that tells the muscles, 448 00:24:41,606 --> 00:24:43,858 which are the motors, to move around 449 00:24:43,942 --> 00:24:47,403 and go to the right spot in the garden and take care of everything. 450 00:24:47,487 --> 00:24:51,824 You use your phone to tell it where to go, how much to water. 451 00:24:51,908 --> 00:24:54,160 Then you can set it on a schedule and forget it. 452 00:24:54,244 --> 00:24:55,954 Once the tomatoes are ripe, 453 00:24:56,037 --> 00:24:59,040 FarmBot can send you a message and say, “The tomatoes are ready.” 454 00:24:59,123 --> 00:25:00,750 “Time to make a salad.” 455 00:25:00,833 --> 00:25:02,877 Fun fact! 456 00:25:02,961 --> 00:25:07,131 Seeds are really picky about the temperature they’ll start to grow in. 457 00:25:07,215 --> 00:25:10,134 In fact, spinach seeds will only start growing 458 00:25:10,218 --> 00:25:14,180 if the soil is between 60 and 68 degrees Fahrenheit. 459 00:25:16,558 --> 00:25:19,769 Wasn’t that cool? Science is the best!
