hi everyone is miss monica and welcome back to construct and stem today we're actually going to start a robotic section which is interesting because we're using something it's a kit that i purchased for my kids spider robot which is a really introduction to bought it and i think it's fun and it's a lot for a lot for the kids to learn and it's a nice project so we're going to want to see work on that i know i've been to a law electronics which you know i love because there's so many great things you can a plus i actually have done this with kids gardeners up to high schoolers because when i work with my kids it's more hands on and i'm working with them so they're not by themselves doing projects and one of the things as a parent and also as an instructor it's you have to be wary of is that there's a lot of things you want your kids to do and there's a lot of fun things out there for you to buy for them to do but getting them to do it if you don't have that little technical background to help them they may not they may start to make it they stop and get frustrated and you don't want that to happen because it turns them off of these type of things so in my class we start with this is one of the things i always do introduction robotics is the spider robot and i feel like trying to do a lot of different things but it's all those with them working with me to make sure they actually achieve something and they complete the project and they have something to show at the end of the class and i think instead i'm in the science technology engineering math when you're going through k through a new working with kids that young is that you really need to have something that they can take home because you want them to be able to look at it to be proud of what they've done and to work on it if they have to make changes to it or if something happens it's a continue education and i see that with the kids who i've been with who've been with me for years i have one gentleman which is funny he's in second grade now  was me in kindergarten and he is now in this group of kids which is second to fifth graders so my class that i was teaching i had ham bone second grader and also the rest of them were fourth and fifth graders in my class  was interesting blend and i forgot he was in second grade and i said oh i was surprised to see him at the school so we were doing another project which is a nice year box which i'll probably do too but we're doing that project of all the kids well i have another girl who was there with me for years to and she did excellent so i guess i should say that a few of my kids have been with me but he actually has been with me longer so even though he's in second grade he was able to help a fifth grader out with the design was completing the project because he understood it and what i'm telling him things to do he knew what to do because he's been with me so it's great to see that and i like that and the the girl i was talking about was good too because she actually is going on to and i'm kind of sad to say that will even some of my workshops and gone on to robotics team which i'm very proud of and i was sure was so we're going to start them and stop talking so this again is the spider robot you can actually get him on bond with me through some of it not to the whole building of it and so i've done that on my own that maybe sixteen seventeen kids would build in of it and it's that i've been doing these for years now and i've done over three hundred of these things  are like i said they're excellent for kids it's just introduction of robotics so i'm going to this is going to take a couple of my t v shows a complete this but we're going to start so the first thing you want to take at the back which is very nice i like it because  senate it's easier to teach the kids what to do because everything's like missile panels that you can do so and i have to say if you have young kids the first thing you have to tell them is how to open up a box which isn't directed because skill that they're going to need in life and actually if they're in a stem environment they need organization skills too so when you get them in kindergarten you get them young you keep working with them to keep them organized an organization maybe a couple of things what i do is i keep everything in the bag in the box  when my kids are working on me on a kit because i want them to stay organized and also they lose parts and i like to tell them that i don't have replacement so you shouldn't lose it so let's go through what's in it for us on the spot of robot and i said this is a nice robot make sure i bring with me when i have classes these low cutters to cut these pieces out so we don't have those pieces on the and pliers because you never know when you need them scissors because scissors always come in handy and also you really need to for the when you get to the end of the robot one of the things i bring with me is my trusty and always my saturn ion because the fact is with this there this is excellent kit and i love the kit but sometimes you have to tell your kids to be very gentle with it because they pull the wires out and you have to solder apec together so when you're teaching this or your work will be kids you want to make sure that they're very careful with that so first thing th so this is something you should always have just a little kit that have extra stuff for you to fix things so one is a father and i was daughter i also have a lot of a lot of stuff here staples whatever i need just to run into problems i can solve it and also as isis scissors cutter and wires and of course over here i have extra pieces because as i said i've done over three hundred on them and i find out is that as i go through my building there tends to be issues and issues involved doing something correctly or losing pieces so i like to have extra so no one you know doesn't complete their their their project so you don't have to do that so if you ordered some for a group of kids you have sixteen kids i suggest you were eighteen because then you had two extra first of all you should always build it on your own something something's going to happen and you need this extra pieces so the first thing i would do is these is the gear box let's talk about the gear box it's the the nice thing about this is that you don't have to build the gear box and there are some gear boxes that you you have your motor and you have this axle here and your wires from your motor that we're going to attach to a battery so and also your switch so if you think about everything we've done in the electronics class where we had wires and we had to switch it all out and we had the l e d but all this is very similar it just teaches them basically electricity which you need to know in any type of stand i think if you're if you're if you're more towards the i guess engineering component of it but i think electricity just a basic thing everybody should know anyway so you should always make sure your kid understands the basic component first thing gearbox love it it's a nice like it is very nice so when i start that with this so this take up to gearbox and make sure all the pieces together and as i said my kids usually have issues and usually issues around the switch where the extra wire if they pull it out and i have to solder it back together which is like i said ok so this is of the small blue panel and this is the first thing when in use we use that because the body of the spider is here and this is actually where you attach your box to so it's very easy to get out and that's one of things i like about this is even for my kids even though i have the cutters i don't really need them for this one there are some of my kids i do need it for one of them so that's a good thing so let me use this first this is actually the body of the spider and also this is what the gearbox is connected to so it's really nice take that out and we want to take out the pieces that you attach to it and the pieces that you don't need are this piece right here because this piece actually allows you to clip the gearbox in place so that piece is and if you are going through with the type of the panel this small panel which is this blue panel here this one is a big blue panel and the piece i just really took out was b three so you tell me three if you want to do it that way and that is a good way of doing it too because when you have your kids stay organized and not take pieces out because actually when you get to the legs you don't want to take those out ahead of time because then that becomes a really big issue so and this panel is which is a nice one which is  a make sure because i thought i saw a i'm always looking around for to make sure i have the right panel ok so we want to take out here this piece right here which is the number four so you want to go here and you know take this piece out so this is a four so you have of the three a four and then we have to take out the cover for the switch so we go back to the small blue panel and we take out this little piece here which is number two it was a b two  would take that out too so now your kids they should have everything they need to build that year bought the put it together so this piece this piece and all everything else you want them to put it right in the back of their bags because if you don't on here and you want to have this facing down so this is kind of going down to the round part of the spider so you just attach it it's a very simple attachment was very simple right and again if you have students you're working what you should always assume nothing is very simple i say that but it isn't one of the things i do now is i actually now i have this attack i want to flip this these pieces together and i use this piece remember this piece i took out so you take this and this is two little holes on the side if you look you see one hole here and one hole here it's at very close to the motor and the motor is the great part if i didn't mention that i'm just assuming you know i'm sorry this is the motor and the zero greenish in here so we want to put this out what i do is i actually put the wires a little bit closer i put i take the black wire out and i put the red wire up close to the body the gearbox to self and i slide this over the red wire because a red wife a little bit longer in the kind of puts it in keeps them place so i slide it over and it's actually the thing about this is everything's really snap and you don't have to you know use screws or anything like that although there are some nice projects out there that if you want to introduce that there out there you can do that so i just snapped this on and you have this for this piece together so your kids won't lose it so s taking little bit longer because i'm on t v and i'm showing you guys and that's always something that happens when i do that but not in my classes ok so we got to snap together and we're going to move on to the next piece so what you want to do now not like i just did ok i'm going to start over i think i'm a little nervous because i haven't done this in a wound i'm going to put this on again like i said going to put this down with snap these two pieces together you put this on the prom and then you come after that's done you put the black wire i'm going to put it down the whole sort out the way now if you notice one thing that doesn't why i was having this and i didn't want to do this because this would cause difficulties but i did i am just like my students i broke the pieces and i always do this and that because again that's why i have my father i and that's one thing about this so what we're going to take five minutes to just fix it shouldn't take long i'm going to try to fix without following because i'm not sure i have enough time to do it online so i'm going to try to see if i can get it fixed so what i do is  o scrape off you know the plastic because again if you're teaching basic literacy you want tell the kids about the fact that electricity actually flows through the metal and the plastic is insulated metal is a conductor and the conductor is where electricity is flowing electrons the flow of the bat so you need that nice connection now the only thing is this actually has a lot on it so and one of two things i can stop right now and fix it or we're going to try to we're going to actually go on i'm going to go through this we're going to go to another piece so i can actually sort of this later but we're going to do all this i'm going to solve this not only mine actually have them i was the web site the solder how you do that but we have everything ready so i put this in here but you switch here you take this wire which should be actually attached to this you take this wire and you actually put it through here who end up doing that and we end up having to solder together those no big deal that's why i have a soldering iron and that's why i love these because it's always nice to stop and show them how that works i don't let them do it because my kids are too young but if i had high schoolers and i was doing th schooled i did actually do in high school we didn't have that problem with a little bit gentle but if i was working in high schools i would actually have solders have a great experience for them to do so you take the switch and you put this  it actually lives up with the other side we're says on and off and the on off the on will be the point you have to make sure the switch the wire is on the side for the on because everything in need and i was going by action when cases were cases happen but of course i didn't think i would do that so that just tells you that i am not perfect even though i've done three hundred these or more ok so this may or may not work i put a battery because i have this initial that's ok with him to keep on going so i take this and there's a hole right here right by the switch you know take this wire that you are really actually twisted together you can actually wait to pull it through if you want to which is ok but you want to pull this through because the purpose of this wire and the black the red in the black wire is to attach it to the battery because we're given our power our energy is going to be from the batter so i pull that through now the black one is actually for negative and the black what is got to go on the other side now they have actually instructions with this and i use some time with my kids the thing is that when i first did it there's some issues with the instructions and i can't remember what it was but i didn't work as well but i always keep them and if i have some of my kids who are really fast builders and they let them go ahead i tell them to they can go ahead if they want to follow instructions you have to go back and you have to check and make sure everything's ok that they're not too far ahead and not making too many mistakes but it's good to use instructions so i like to keep you know with me i built so out need them but i think it's a great thing to follow instructions because it also teaches your kids how to follow those drugs gins some of the younger kids you probably will not use instructions with and i actually don't use it but most of my kids but the kids who are  this man may not work because remember i pulled that wire weight on the switch and the way this circuit works is a very very simple it's actually going from your positive to the switch and from the slit the the wire from the switch out to the battery springs in your case one looks i have to say like a christmas tree which i've been told by my students so this is why i'm you see this and this is one that's a flat more of a flat spring and the spring is the way you see for the positive and this spring is mainly for the negative so you want to take the one that looks like a christmas tree and you want to tack it to the black wire now the way you do that is the same thing you did earlier that i did earlier where i took this and i twisted it since i haven't taken off the wire here the plastic component the wire i can we can do it now so i'll just hold it because if you just wish that you can pull it out you'll pull it out from the motor you don't want to do that so just touch it gently twist it together because there's multiple strands of wire and multiple strands of wire need to be twisted together to make one strand which you know when the things they do with the brooklyn bridge which i thought was always interesting that i read about that is that the when they built the brooklyn bridge there were multiple strands of that you know the the the stays that's coming down and what they did the rolling they took the wires and they actually made one big one stronger by actually taking multiple wires strong steel wires and twist them together so that how i guess whether a reasonable bridge is still standing but that it's a whole nother class that i'm not going to go through now but i would think it's interesting to think about so you twist this up and now take your spring that looks like a christmas tree and if you notice on the tip of it there is a circle that circles got a allow you to do the connection between the wire and the spring so you take this and you just slip it on the wire you just twist it which is like one big one big wire now really not big but there are a lot of strands of small one so you want one solid one so it's one solid wire you just slip on the circle and very simple and then you bend it over and then you take it's very simple right then the nice thing about this design and that's why i use them all of time because i like a lot of things about it is that you just take the spring and there's a little i'm alone not here that you probably can't see but when you look at this a little do it on during the show but this is all it is this is the first piece is actually the gearbox attached batter's the to the bottom to the body this takes about it depends on how many kids you have this takes about i think three hours maybe so if you have fewer kids doesn't take as many you have more kids might take more but i'm going to wrap this this show up because my time is almost out and we're going to move on i think it's going to take maybe three to three shows
