  1. Hello my mbot ranger dont work with tablet app and with mblock program .how i can reset my mbot ranger factory setings?

    1. Hi Vaidas,
      I have added a FAQ about how to restore factory settings – Q18. You can check the Q18 in FAQs.

  2. I got mBot Range Kit and assembled it. It runs ok. I would like to start some programming to change its behavior. I wonder how to start first. Will the pre-loaded programe be erased? If there is something wrong, how can I restore back the pre-loaded program.

    1. Hi Hammer Chui,

      The pre-loaded program will be erased after you uploaded your own program.
      While you can restore back to the factory default program refer to Q18 in the FAQs part on this page when there is something wrong.

  3. I got the mBot Ranger kit. The quality is good. The packing of components are well organised. However, I would suggest the bags of component to be well labelled corresponding to the user manual, e.g. M4*8 screws….. It will be much user friendly for those non-technical parents and children.

  4. I just bought a set of eBot Ranger kit. The quality is good and the packing of components are well organised. However, I suggest some bags of component should have proper labels in accordance to the user manual, e.g. screw M4x12…… It is very useful for those non technical parent and children.

    1. Hi Hammerck,

      Thanks for your valued advice, we will add it into customer advice list and take it into consider.
      We are glad to hear more suggestion for you to make improvement.

  5. I love this kit but I use it in a classroom setting and the parts get some abuse. Some of the motors have stopped working. Where can I buy replacement motors?

  6. I can’t get mBlock 3.3.7 to start on my Mac running 10.11.6 as it is not signed or from a known developer. How do I run the application without compromising my security settings?

    1. Hi Roger

      The mBlock is safe, please do not worry about that.
      Is it possible for you to ignore the warning message and install the software.
      Normally, when the software is installed successfully, you do not need to modify the security settings.

  7. Why not have the battery compartment with a flip down opening in the back ?
    That way you can slide the batteries in and out without having to remove screws etc ..

  8. I am trying to drive steadily with my ranger, but it will not do this. If i say it should run forward at 100 rpm for 5 seconds, it stops after approximately 3-4 seconds, beep, and do nothing afterwards. At higher speeds it won’t even run for a second (250 rpm it will only do for 0.2 seconds!) why is this?? It is on a flat surface, nothing is nearby, so I don’t understand. Please help!

    1. Hi Jessica,

      Please change the battery for the ranger robot have a try.
      According to our test and research, it is suggested to use rechargeable Li-ion battery or rechargeable nickel-metal hydride, nickel-cadmium which can be bought from amazon or local shop. Or Alkaline battery with good quality like Energizer, DURACELL.
      If still the same issue, you may upgrade firmware for ranger and see if it works ok with factory default program.

      1. Okay, I will try with different batteries, but I doubt that this is the problem, since the robot did this right from the start with fresh batteries.
        I’m now also having the trouble of resetting the default mBot Ranger firmware… It constantly says upload failed.

        What is wrong with the robot? 🙁

      2. Alright, resetting is done, but no effect, neither do new good quality batteries.. It still errors when moving: moves a very small bit, then stops and beeps. How can I solve this (i need this robot for a project next week… :S)
        Thanks!

        1. Hi Jessica,

          I will send you a simple program for test to your email address, please check it

          1. Hi Fabian,

            Do you mind to describe details with the issue on your ranger. It doesn’t move when you set the motor speed large?
            I will also send you the instruction to upgrade firmware for it have a check. Kindly check the email and refer to it.

  9. i tried to upload blink example from arduino software. It was not working.
    But after that my phone is not getting connected to makeblock device and i cant control the device using mbot ranger application.
    What to do next.

    1. Hi Prajesh,

      Please upgrade firmware for the Ranger have a try.
      I will send you the intructions to your email address, please check.

    1. Hi Sergio,

      Please upgrade firmware for Ranger have a try.
      Once still the same thing, it is strongly suggest to change the battery for the robot. According to our test and research, it is suggested to use rechargeable Li-ion battery or rechargeable nickel-metal hydride, nickel-cadmium which can be bought from amazon or local shop. Or Alkaline battery with good quality like Energizer, DURACELL.

      1. What is the voltage rating for the rechargeable batteries that you recommend? The usual AA batteries are rated 1.5v but a lof of the rechargeable AA batteries are rated 3.7v, arent’ these going to damage the main board?

  10. Hello,

    I have mRanger with Bluetooth , I can connect well and use mblock to control it, but when I do some code and RUN the code, the robot doesn’t do anything, could you send me instruction to my email how to update de firmware o mBot ranger 3 in 1 version, as well how to code from tablet and execute in the robot. I try to find but only found videos about mBot normal board, not the board of Ranger.

    Regards

    1. Hi Maiquel,

      Will send you the document guide upgrade firmware for ranger robot. Please check later.

  11. Sorry,

    I forgot to say, I have Windows 10 and mBot Ranger 3 in 1 Bluetooth version with latest mblock application for Windows installed, to update the firmware need to be using USB cable and in connect menu which option I use? COM or Bluetooth ?

    Regards

  12. Help! Just built my mbot ranger and isn’t working, the lights are on, but It doesn’t move, and I can’t even turn it off. I’ve updated the firmware as suggested from the pop up on the app (unrecognizable firmware), but still doesn’t work. Please can you help?

    1. Hi Gethine,

      The Ranger robot is different with mBot, please make sure you have chosen correct board while upgrade firmware.
      Please upgrade firmware for the Ranger robot with mBlock software again, please refer to the FAQ 18 in this link:http://learn.makeblock.com/en/ranger/#FAQ
      Besides, if the robot doesn’t move after upgrade firmware, please change the battery for it have a check.

Or Alkaline battery with good quality like Energizer, DURACELL.

      As for the issue you can’t turn it off, please keep holding the power button for several seconds.

      For further feedback,please send email to tec-support@makeblock.com

  13. I bought my mbot ranger yesterday. I connected it to my tablet via blutooth. Everything was working ok. Then, I started to do some programming via usb on my PC (wondpws 7). I have the latest version of mblock. I upgraded firmware at the end. Then I tried to connect it again via bluetoth with my tablet and it can’t connect. It does not work. The communicate ‘wrong firmaware’ is appearing on my tablet. What is wrong? Hiw can I get the right firmware? (tablet with Android 4.4)

    1. Hi Magda,

      For this issue, please reset defult program for the Ranger robot with mBlock first.
      I will send you the instruction to your email address, please check.

    1. Hi, Lance,
      Brass stud M4 * 30+6 is not available at Makeblock’s online store. Please kindly check other store.

  14. Hi. I have just updated the firmware of my Ranger and now when using the Makeblock android app obstacle avoidance mode, the bot avoids some obstacles but then when tries to go backwards it starts sulking forward and backwards. I have tried to test the ultrasound module by placing my hand infront of it and reproducing the problem. At an more or less close distance from the ultrasound sensors the motors start the sulking behaviour until the hand gets closer or further away.

    Can you please help?

    1. Solved it!

      It tried once again to upgrade the firmware but this time i turned the Ranger off.
      Now the obstacle avoidance mode works well.

      On a side note, the app mBlock does not seem work with the Ranger robot. Is there any fix for it?

      Also, on your website there are at least two dead links for programming instructions (scratch for example). It is confusing all the teaching materials and they are not very well organized. I am not able to find the Mars project for the ranger and this page gives me the feeling that it is not up to date. It would also be good to have the adventures of Mike ( or whatever his name is) in one single document instead of having it divided in several documents.

      Feedback is appreciated.

      1. Hi, Pedro,
        Glad to hear that you have solved it!
        mBlock app V0.8.1-EN could work with Ranger. Could you double check with your mBlock app please?
        Thanks for bring us the attention to update the links, and we will report this issue to related personnel to fix those links.
        Feel free to e-mail to tec-support@makeblock.com if you have any further questions and concerns.
