Thanks for that video and the block download on your website. Could not find the correct ev3 block anywhere else. Import works and the first programm is runnig. But I have a problem with the block. The description is just 'Missing Displayname', so I'm not able to know what the different operating modes are called. At the moment it is just try and error to get an idea of each operation. Have you ever heard of the problem? Thanks in advance
Hi i already try to connect the ir seeker and compass but it doesnt appear in port view .I also update my firmware to latest version but still it doesnt appear. do you know why ? i need help
Are you referring to the HiTechnic sensors? They are not recognized in Port View quite the same way as an EV3 sensor, but you should still see "I2C byte" or something similar appear in the port. If you do see this, no need to worry, as it's working fine, you can then proceed to program the sensor.
Hi, Do you know if we can we use IR sensor of EV3 (31313) instead of Hitechnic IR Seeker for detecting IR signal from Hitechnic IR Ball(IR 1005).. Thanks Dude.
No, the IR ball emits a very specific IR frequency which, as far as I know, cannot be detected by the EV3 IR sensor. You will have to find the specifications for both sensors and the IR ball to verify this though.
Thank you for this video. I'm currently making my soccer Bot using EV3. My bot currently use 3 sensors. compass, IR seeker and the ultrasonic one. Also, I have the HiTechnic Infrared Electronic Ball (IRB1005) & the latest EV3 Seeker, compass block (which is different than yours in this video). However I'm having issues with the IR Seeker. Just like your program, I have my IR Seeker Block in measure mode followed by a switch with all the cases possible. All my cases use a move tank block with the mode : turn on 0 = turns to the right 1-4 = turn left 5 = forward 6-9 = turn right. A simple program nothing else added, but my soccerbot sometimes gets stuck. If the ball is in front, it will turn right then left then right.. over and over it does a constant sweeping move. It switch between my case 0 and 1.. case 0 turn right, case 1 turn left. Also, my robot sometimes go forward when I place the ball behind (range 0 ) I can't seem to find the solution to this problem. My IR ball is in 1200hz mode.
I've used the IR seeker myself and it is a bit tricky to work with. The sensor needs to be placed low (level to the middle of the ball) but still on a place on the robot such that it has an unobstructed line of sight and is at least 5 cm away from the ball at all times. It's difficult to design a robot to these specifications. I recently designed a sample soccer robot, named "Pollux." It's not yet available on my website, but I hope to have it up soon. Look for that as an example.
Yes, power differential always depends on several factors (robot design/purpose, user preference) so I cannot provide a single value. That's up to the builder to experimentally determine.
Thank you so much.Tell me please, in what numerical range does the sensor produce signal strength?
I don't recall, but you can find this info on the HiTechnic website.
How does this sensor work in Python?

If you put a few beams maybe one or two, in front of the sensor by about 5 cm, will that affect the actual readings of the sensor?
If the beam is in the vision path of the sensor, then yes.
@Builderdude35 Thanks
i keep downloading things on hitechnic website but it doesnt show up on my bricks and i look to import them but i just cant find them
Have you seen my video on importing sensor blocks? ruclips.net/video/Jcb6r4KbHo8/видео.html

Ok bro thanks.
mine hi tech ir seeker does not show stable number. always shows different number. ex(120,40,23, ....)
would you know where we can get the one your using? the one at the moment iss an edited version by T2h
Available on the Modern Robotics website: modernroboticsinc.com/product/hitechnic-nxt-irseeker-v2/
How many degrees does the IR Seeker view? I originally thought 270 degrees, but that didn't seem like enough.
You are correct, the HiTechnic IR Seeker sees 270 degrees, which is actually a lot.

Thank you for your answer :) I'll try this and see if it's way better.
How to download the block?
You can find it on the manufacturer's website, hitechnic.com. I have a tutorial for importing these blocks into the EV3 software.
Ya I saw it already, thanks a lot man
Thank you)
Builderdude35 thank you
i had checked the range of the ir seeker and it turns out to be unequal
Hey! I have a question, would the power differential be different depending on the robot, if not would you be able to show what they are? Thanks!
Yes, power differential always depends on several factors (robot design/purpose, user preference) so I cannot provide a single value. That's up to the builder to experimentally determine.
How did you know that?
+ Mazhit Zharaspai Mad hacks. XD
Are dribblers allowed in 2016?
Not sure, I didn't get involved in WRO this year.
