  • Open Robot project: code and 3D design files are open and shared. You could personalize your robot as much as you want.
  • DIY & Hackeable: BROBOT is not a closed final product, BROBOT is an open, modifiable and hackable platform, perfect to learn and play as much as you want!
  • Develop your own apps: You could modify the source code of BROBOT to perform new tasks but the communication protocol is also open, so you can develop your own IOS, Android, PC remote apps to control your BROBOT!
  • Learn: BROBOT is a JJROBOTS product and this mean that you will receive a well documented project (source code and external documentation). We want you to know all that is happening inside your Robot! This is ideal for learning and teaching technology. We will provide very good documentation. How we are controlling the motors, how we read and integrate the information from gyros and accelerometers, how we are controlling de stability of the robot, how we communicate with the control apps, etc…

– Build with your kids, at school, for yourself… this is a unique gadget. A perfect STEM education robot

– This self balancing robot has a medium size, perfect to carry your own beer (or mineral water ;-))

– There is a community behind BROBOT so you will have a forum to ask questions, share your experiences, MODs/ Hacks and contact other users…

You can use these self balancing robot parts to create more robots or gadgets, keep in mind all the devices used in a BROBOT are standard electronic devices with a lot of potential. In the JJROBOTS community we want to show you how! You are now buying a self balancing robot, you are buying a versatile set of electronics and ancillary devices.

    Very impressive robot. I have bought 3 units and me and my students love it. The Arduino CODE is both simple but powerful. And the PCB is very customizable. We have been using the wifi connection to control the blinds with the motors included in this KIT 🙂
    5 stars!

    Perfect to teach my students about the PID controls. They have been playing with the B-robot PID parameters and seeing how they affect its behaviour. I have been looking for something like this months. Btw: great design

    Great robot, very easy to follow video on how to build it.
    Love the whole idea around it .
    i like building things but i am not that good in electronics and programming.
    This way its easy and very educational.
    The robot has a high fun factor like all the projects here.

    I can easily customize the robot

    Added my customised bumper!. Great feature jjrobots 😉

    Fun for students and educatorsThis is a good project to teach something about robotics and 3d printing. Instructions are easy to follow and fun to build. You can create your own accessories for these cute robots.

    Great robot to generate buzz for our makerspace!We ordered the B-Robot Evo 2 because we had a request to spotlight Arduino Controlled Robots at our makerspace for a television interview. Parts are easy to print and build instructions are easy to follow, especially with the build video available. The Android app is simple and easy to use. This little guy gets a lot of attention and generates a ton of buzz around our makerspace booth. Definitely a fun, open source, hackable project that’s well worth the asking price.

    First finished 3D-Printing projectA really nice Robot project for Beginnes of Electronic and Arduino. I printed the parts by my own. This was also a nice work for beginners. The parts are very exact the holes sometimes are to small, baut this is a good result for me because I can drill the holes to the needed diameter. The Evo-kid includes all you Need if you Print by your own. Till not there are Mann add ons and I hope they never end with new one. The. Shipping was very fast. Thanks for this robot. I hab a really positive first project. Sorry for the not complete finished robot on the image. I am still working on it. Printed with Anet A8.

    Almost perfectI have ordered he 3D Parts too. Good printed, but the wheels were too big. I could not put the rubber rings on it. In the video you write ‘It can be done’. For me it couldn’t be done. I have printed another set of wheels with my Ender3 and PLA. They where about 0.5 mm smaller in diameter. Now i could mount the rubber rings. They fit perfectly. Anyway i give you 5 Stars. Good product.

    Fun and Fast!

    I never though a robot like this would be this stable and …fast!

  21. Avatar of Ooops


    Great project!Had fun to print the parts and mount it with the electronic components together. I would highly recommend to create new building instructions. It was difficult to build it just from the video clip: No description what bolts we have to use, an old arduino board, just a dark scene when it comes to mount the servo… So I give 5 stars for the robot, but only 3 stars for the instructions. However: Great project!

    Too big!

    I thought it would be smaller than It is. Its size make it too big to run under the lower shelf of my office. This is not a problem actually but I wanted to mention it

    The packet got here late

    I was expecting the order to get here within 2-4 days but I have to wait a whole week for it.

    I really like what you have done with 2 NEMA

    The design is good. the control : superb. They are 2 stepper motors! You feel them like brushless motors controlled with an ESC

    I got 2 units to race. No regrets

    jjRobots created the custom KIT for me (I did not need the motors as I have some of them around) and I got two customized kits. The balance of the robot is shocking. Even kicking it, it will not fall.
