LEGO SPIKE PRIME Out OF Order Delivery Cart Debugging Program

hi guys welcome to save our honey so we

build a delivery card which is out of

order

[Music]

happy Father's Day guys so my dad is

gonna show you how she all right so what

do we got here so we got up out of otter

Kart and you want to fix it so let's

look at the program all right so let's

start from the first block so the first

block says when you press the left

button on the hub which is this button

something should happen and let's see

what is that something the first thing

the see there is a sensor here either a

motor or probably a motor which is on

sensors see the speed for that murder is

will be set to 100% and the C will go at

the the motors motor directions or more

motor movement will change to the zero

position and then we'll set the movement

on motors a and E a and E are connectors

where two motors will be connected and

then it will basically set the movement

speed to 50% and then it will start

moving until it finds a a sensor which

is which we have connected to the V

connector on the hub and if a distance

is closer than zero centimeter which

technically means that it will it won't

stop it will keep on moving it will

never detect the zero centimeter and

will keep on moving and we won't be able

to stop it so first thing let's get

let's hit the initialize the program and

now we'll hit the left button and see

what happens alright nothing is

happening so we're gonna start debugging

it right now if you see the the section

here the group of blocks here are

highlighted in yellow which means that

the command the left command is picked

up by the first block here so now let's

see why the C speed is not set to 100%

so I'll click on the C here and I see

that there's nothing connected here on

the C however I have motors connected on

B D and F so I should be using one of

these motors so now we will see which

one

is actually the motor that you're gonna

replace at position C so I want this

this motor which is going to be our

directional motor with and that's the

one I want to first set the position for

the rotation for so I'll try to track

this cable and see what connector this

cable is connected to and in this case

it's the D so we'll change it from C to

D which is this guy alright I will

change the connector from C to D here as

well we will set the position to zero

which make sure that the cart will go

straight the next I'm gonna set the

positions

sorry movement on motor a and E which I

believe is also not accurate so we need

to select motor F and B so there's two

motor than F and B DB already selected

so F and B I'll quickly show this one is

the left side motor and it's connected

to the F and this is a right side motor

and the wire is connected to B so we'll

select F and B next we'll set the speed

to 50% I will start moving straight so

we'll know it straight there you go

alright and wait until B let's see what

is B B should be our distance sensor

which is this guy here and it's

connected to all the way towards a so

it's not connected to B it's connect to

a so we do change it so change it to a

and then we also need to give them

distance if you don't give any distance

it will basically keep on moving so I'll

say distance of 9 centimeters as soon as

oops sorry not 99 9 centimeters as soon

as it sees an object at night sent in 9

centimeters it should stop moving

so we'll start see if we debug the

program and fix the issue so this is my

stopper as soon as the modern age is 19

it should stop so let's press the left

button the left button is the one that's

going to trigger the the motors so here

we go one two three all right

oh all right let's do it one more time

as soon as this reaches ninths

centimetres distance it should

automatically stop all right next we

gonna fix the block which is responsible

for movement when we click the right

button this is this guy all right so

let's read it it's got a pretty

straightforward so we already know that

the motor for the directional motor

which is the back motor the bigger one

is on D so I'll move it to D and keep on

changing these two D as well the set

movement motors so if I wanna set these

models I know that en a and E does not

have any Morris I know F and B have the

motors from our left button program

we'll change it start moving straight a

wait for the sensor that B will check it

sensor is not at the B at B we got a

motor sensors on a so select a here

closer then we'll change it from 0 to 9

centimeters because we do want the car

to stop and after that I want it to stop

moving

now we set C shortest path C is same as

D this is our directional motor will set

it to D and then we are going to look at

the moment the moment it says this will

go forward 50 centimeters I will stop

then we also need to go back to D here

and it will set the position to zero and

then I want to make sure that it goes

back and then goes forward so I want to

change the direction from backward to

forward 50 centimeters 50 centimeters is

a lot of space on our you know

workstation or what desk here so I want

to make sure that doesn't fall off or

works what this so will make it go at

least 30 centimeters

so we make sure it won't fall off our

work table all right

I'm hoping this is gonna work let's hit

the start button all right it's

initialized we'll put our block here so

that it can detect the stop block I hit

the right button goes straight stops at

nine centimeters wait for one second

goes back and then stops again wait for

one second and goes forward and stops

again thank you guys
