so this is all assistance for you if you're working on the third item on the list of basketball I'll ask you to repeat something over and over again and to use a when started block so or repeat block so under control you'll find a braid a loop knot Loop is going to go through the code bounce back up and it's going to repeat for the number of times that stayed here what I'm saying is is that they are out of piece of code and have it go 10 times but how's the drill as asking us to go increasing distances away from each each time we come back so I wasn't about to pull drill you run touch the line come back and you go to the next line further away further away we needed somewhere to make the robot a little bit smarter in terms of politics okay so the variables are set at the very beginning of a program and they allow you to make an adjustment or set something so you can call it out a different places during the program and that variable is something that you can then manipulate at different places in the program also so we are going to create variable by going to make adorable and I will call the variable basketball okay and you'll see that will get a basketball here and now basketball appears over here also okay so we're going to stop the variable and we're going to bring that in so they started the program to Congress so now the variable at the 200 anytime you call I basketball it's going to know that that is 200 mm so part of the cow remember says build an algorithm to move through all 1 to 8 grade squares in sequential order you should move to one go back to the start move go back to the store continue the platform all the way through the squares so we know it has to return. 8 * 2 now we want to tell it what to do so we're going back into our drivetrain and we're going to deal with what we wanted it to do before which to drive forward for 200 except we are not telling us drive forward for 200 we're telling it to drive forward to basketball cuz if they are variables and we dry over the basketball on the truck back to that location basketball 200 m m okay so once it reaches between MMR can wanted to rotate right so we told it to turn the number of ways to do this evening say turn heading so so it knows it's turning around and then it needs to drive forward again to drive back to run back to the line where it started this is where we're using basketball the variable so there's basketball is variable go back to my drivetrain and then when I get to the end I need to do the turn right so then I can do at turn of any kind of go ahead and you can do a turn last turn here spins around 180 degrees it's going to set the variable to basketball it's going to drive forward turn hundred eighty drive forward again repeat that over and over again it's not going to move off the 200-mark it's going to stay at 200 because it doesn't do anything to go back to my very able to see that I can change the variable by a certain amount of numbers so that whenever if I can adjust the distance it goes I'm going to sell it to increase buy 200 so now and I'm going to increase it to I could have said increase it by basketball by the way but 200 works and then after looks around it's going to stop somewhere to tell her to stop driving I just make sure it goes to the right place so once I have that in play there's a bill before this to run its course so if I go ahead and do start a load and play and what's wrong with that you'll see there it does its first 200 m m it's rotating around heading back out doing another 200 plus you take any further turn and come back I had two hundred more to this and it's going to keep repeating this until it's done that 80 times so you can see at working across the floor and completing the course so all I run is for Melanie Moore I'm exhausted just watching this floor sprinting sway back heading out for the last time there it is so well done Little Robot round the course fall Dakota gray nicely so obviously I like that I would say scare and you'll see that pop up in the corner right here that's in my downloads so now I can take that and I can upload that on to the Vex teams okay so I hope that makes sense to you that's an induction of a variable again variable set a program and then to change account which is using the variable to an anniversary edition and repeat function okay
