6. Sınıflar Örümcek Robot Yapmayı Öğreniyor

so today we're going to start building the robot so we're going to first watch a video we're gonna watch them all together at once but you and your partner will be watching them at your own pace to help you with the steps so first you're going to desolder the LED light resistor and black wire and when you watch the video again it'll make sense you're going to heat these two dots up and pull out your LED there you go I took out the LED I just dropped the LEDs and you need to strip off about a quarter to a half an inch of insulation on both sides [Music] okay think it over take it all out we kind of stand the motherboard so we have to take the rest yeah we're just gonna throw it away anyway since it's the light bulb and we don't need the light bulb yeah we do okay and now we're gonna watch the rest of the video to see what we should do next um had a bit too much wire we like to [Music] let CPU CPU and a computer let's roll with these vote for those is you always have to have the one because something could go flying at your face and your projection from them to show them and then have them be able to do it give them confidence right um you know and then when they did it they felt very successful and proud of themselves as I said you know this is where I struggle with the most you need to watch the video because this is not your next day would you mind going back and watching the video and seeing how you place your wires I see that the numbers are faced up on this side but face down here what's I do they need to be faced up on it a lot and where do the wires go they go in the yeah and if we bridge that gap what's going to happen yeah so what's I do they need to be facing out perfect and it needs to be how many inches apart yeah it's where the wires go into the motors keep some of them don't loop them right and so they'll fall out because though the wire the loop should have a little bit of a twist in it so it like pushes against the metal tab on the motor but it's a subtlety that's maybe lost on in the video they we watched that part about where how to twist that wire oh and that's when he said he goes oh I know what he did I know what he did and so then he was able to and I saw him twisting the wire to make sure that the wires got pulled out so now at once we ready glued everything together now we have to try and pull the wires back in so but the problem is it's very loose we might actually have to it's too wide for that hole yeah what's a good solution okay show me what you do I do think that it was really exciting to see the kids can go their own way and try it there were a couple of students that hadn't done the wire stripping themselves they had found other students don't know how to strip wires they're like no I was like wow how did you get it done so we gave it to some other it goes both away there the kids like itching to do it let me do it for you well and I would hope that for those kids that are just on this racetrack to finish and then they get to the end and stuff doesn't work that there's a lesson in like I hope they have some time to you know to make the connection of well okay I didn't pay close enough attention or because a lot of them don't get an opportunity to learn like this oh yeah where they're really responsible and someone's over their shoulder every second say no wait that's wrong you need to fix it up so I love the fact that we took a step back today and I saw some stuff that I was like that ID because we were not saying it they were watching the videos yeah I was very happy to see that but I think that was that was a good one they actually watched keep things from electricity for the rook blonko and conductors conductors I thought it would be easier than this yeah I don't go too fast you own these definitely myself plenty so this looks different now what did you guys do before it was facing horizontally and then we made it so it was vertical awesome so and it fits together better now right yeah it lays flat yeah awesome good job it says today we made a circuit okay on our switch what is a circuit we need to take off the insulation so the metal can complete the circuit when we push this switch it closes it hits a piece of metal they want me to close my circuit and then it can open it where do your black wires need to go in your term vo block in the center and the center why because the center these are kind of our negative charges and they're positive those are the power wires and this is gonna tell what the Earth's two already know what to do basically I think you know the outer portions of the wire like the yellow parts insulation are the reason they're basically resistors so that the electrons do not if the wire touches another wire the those the electrons don't flow to that wire it's short out the circuit bring it now sometimes he does that every time I show somebody if you try your switch it should light up right it should light up what does this switch do aside from turning it on and off switch wouldn't work it would just stay on the whole time looking just now well we soldered in the wrong spot where the switch was it was supposed to be right here but that we soldered it right here the switch is working closes a circuit because open it's when it won't work it's a conductor yeah that's perfect okay so a motor controller controls like the speed and direction of the motor so how fast it turns and like what direction it goes and supported backwards and you can always undo that in the program [Music] oh I was working silent right [Music] [Music] No [Music] tonight I have created you see Santa we have to do is we have to please the blinds we basically just finish it today and we have enough activate escaping and that doesn't work very well yeah [Music] [Applause] [Music] [Music] [Applause] [Music] you
