Mindstorms EV3 Tutorial #7: Use the gyro sensor

[@pyrotection]

Very useful for making a stabilized tank cannon. Lots of fun!

[@kenahoo]

For your first program: I'd suggest that instead of changing the termination condition to a little less than the target, change the speed to still be a small positive number when it reaches the target. For example, if your target is x degrees and the current sensor reading is k degrees, make the speed be something like 30*(x-k+5)/x, to start at speed 35 and end at speed 5, no matter the value of x.

[@smitharayala]

Hi Kevin, I did exactly as you did to move the Robot straight. Unfortunately, my robot does not move back to the intended straightline when I move it off the direction like you did. What I also did not understand is, the reason you are using gyro sensor reading to write into the variable staright angle but read the target angle to calculate the differnce. Please help.

[@trampbuddies2004]

Hey smitharayala, I've done the program as well and found out that it starts spinning out of control. The simple thing to do to the program is to change the math block to addition, instead of subtraction. That should fix it.

[@didierhelliet9591]

The student did the straight line but if they add something after the loop, nothing happened. They want to make the robot go straight with the gyro sensor like you showed on your video but they want to add an other senser the tactil one and an other motor.

[@daveslurz]

Any chance you can help me trouble shoot. my code that I copied from your tutorial is stuck in the loop. it just turns. I checked my ports cables restarted. Still just makes a turn Any thoughts on what to look for all the wires on the math block seem fine too

[@benciruiz6493]

Hello, my robot does not follow the loop instruction for exiting, I have it program to move just 3 rotations and the robot just keeps going. Do you now why?

[@dolevvudinsky587]

Thank you so much. You just saved me and my team. You have no idea what this mean to me.

[@rishishah575]

Sweet video my team is in FLL and this was very useful

[@ihmsstudent7195]

I'm having an issue with the 90 deg turn... it doesn't quite make it to 90 degrees, then kind of pauses and waits and never quite makes it. So it doesn't move onto the next part of the program. Any ideas?

[@kevinbriggs8354]

+Ihms Student Have the exit condition of the loop be a few degrees less than than your turn (in your case 87 degrees) This will guarantee it exits the loop.

[@ihmsstudent7195]

Thanks I'll try it!

[@chainbreaker9079]

I m wrighting -90, 'cause im going left but my robo starts spining, y?? help plz fast, for straigh going

[@kaiserindustries5567]

Why is that Robot blinking green on the left sied at 11:50

[@primestudioandphotoshoot]

Thank for your tutorials, after your tutorials, I built two three different my blocks - if I test the myblock individually it works as expected, but did get the same result all the time if I am trying use these myblocks to move the robot such straight - turn 90 R - straight - turn left 90 L also, I have another myblock with the input of speed and number of rotation all these combination of my blocks. Problem I have is if have 3-5 these types of myblocks, program just stop middle, not sure what wrong with the myblock. Can you help?

[@eugenechoi9146]

i tried the code but my robot keeps on spinning forever. what's going on?

[@shafwananis3991]

the robot did turn 90 degree well, but the programme still running,help

[@XenoBray]

ITS PRONOUNCED YEERRRRROOO NOY GYYYRO YERRROOO

[@ruslanusmanov3514]

In the very last program you forgot to change variable to "straight" on reading. That can cause motor to circle around, unless the sensor pointed to calibrated direction.

[@arnavprasad7594]

change which variable to 'straight'? hello people

[@murraybrown5521]

great video! Are you able to provide the algorithm (robotc) for reducing the speed while turning? many thanks

[@pikaninja2308]

How do you make it turn left

[@mostafahusseini6473]

Hi Kevin! I can not find the gyro sesor in the software. There is not any selection or button in the software for this .

[@veebhushah9667]

you need to dolold the brick

[@THEQQMJ]

where???

[@THEQQMJ]

never mind

download gyro sensor block in ev3 g

[@elsantanax]

Hi, I'm a student at a university, I could make a video LEGO robot solving a labyrinth and also please explaining how is the programming.

[@xuzhiyuan71]

Hey Kevin. I'm a 7 year old boy who is new to ev3.I would like if you could post a video about abundant light intensity.I have already watched many of your videos and like them but I could never find one with abundent light intensity

[@ZebraSlapper]

shoudn't you be 13 to be in youtube

[@xuzhiyuan71]

I did all robot stuff with my son including watching youtube for EV3. thanks,

[@bosssmer]

I have a question, Doesn't matter where whe put the gyro sensor?

[@hamzasaeedmalik8062]

The axis matters

[@vihaanprakash3679]

Yes I need this

[@thillock]

Moving in a straight line. This only works once, when used a second time the program simply exits. I have not traced down just how the variables are not using the current heading on the second use even when reseting to Gyro to 0 before it runs.

[@hamzasaeedmalik8062]

To use that program repeatidly you have to reset the motor values at the start of the program

very useful tutorial! Thanks!

thanks

[@xuzhiyuan71]

please post a video about abundant light intensity

[@brianliu9552]

thanks this is pretty easy to understand

[@chezzyboi3334]

well explained.

[@gaojohn9452]

very good ！thanks！ it's a big help to me！

[@tahachaf1683]

thank you best robot programer

[@valliammaisubbiah1092]

this was useful thank you and I named the same things as you with out knowing no what you did but thanks for the help

[@ayyoubalkhayyat574]

Great channel thumbs up for sure :)

[@Skurk11]

Hello Kevin! Great stuff! I'm a teacher too and just starting to learn the basics. Will there be more tutorials?

[@ParthavGavini]

U better than Ninja

[@tridentgamer9248]

what's with the second voice

[@ajt1992]

fav part of the video is 12:13 🤣

[@liamsuidan6510]

My robot won't turn the other way, any suggestions, thanks, great video!

[@lucasfranck1486]

you need to do -90 degrees en -100 for turning

[@shotzz8660]

bro cant you just do greater than equal to 90

[@gaojohn9452]

why the target value can receive the straight value.is not the same constant！i can't understand.my english is on the way .sorry！

The robot has a slight list, but otherwise your robot straight program is perfect!!
