B-Robot EVO KIT (Plug+Play version)

I give it 1 star for the transport, the package arrived broken and some materials were missing, but I spoke with the technical service and everything was solved.

The order arrived later than expected, the shipment was delayed on the way, but the performance of the robot is good.

I ordered it without 3D parts and I printed the 3D parts, but they did not fit perfectly, when the kit arrived I modified the tolerances of my printer so that they fit. everything was finally fine

I ordered this robot and I thought it was sent already assembled and ready to use, I am not very skilled but it was not difficult to assemble it, in the end I am happy and I can say that I have learned something new.

Perfect for disconnecting from work and having fun with my family, looking forward to ordering another robot soon.

Pleasantly surprised with the experience from the beginning, with the assembly and the result. I have assembled the B-robots with all the kit and it works great.

With this robot I start to learn electronics and programming, sure to be the first robot of many, I will follow

This is the 3rd robot I have bought from jjrobots and I think they are great, they are a team that has always helped me with any problem.

Nothing more to add. it’s the robot I was looking for to ride and play with my kids.

Perfect! Working flawlessly

Good robot alternative. Good support and easy to print and set up

Small and nice robot!

I think it’s great, nothing to add

I bought 2 units, no 3D printed parts, printed them myself and everything went well. The support team is quick to respond and always helpful.

Fantastic robot and fast shipping I give it 5 stars

I bought the robot with no previous experience. It was fun to assemble, quite easy and I learned all the details. very well the option to connect to the board with USB and Wifi, can give a lot of play

Meets all my expectations, free and intuitive App, open source and modifiable, reliable and trouble free.

Very configurable robot, both in electronics and 3D parts, I printed my parts combining the colors to my liking, I have been great.

Robot to play with the cat, fun when you run after the cat in the house 🙂

We assembled the robot and modified the Arduino code a little bit, it was easy and it is ready to go.

I didn’t know I could use my smartphone to control it, I enjoyed it.

The robot for a MAKER like me. My kids really like it. Easy entry and modification robot, not your typical battle robot you can get. This is something else.Thank you

Using a 3D printer to create the robot’s body makes it very interesting.

A good robotics kit for fun!!

I found it by chance in a forum, I think it is a great robot, entertaining assembly and very funny the

Good kit, I prefer to buy one of these kits rather than one designed in China.

Not bad at all. The control APP works fine. Good overall kit

I have done races with my friend’s robot. Not easy to stand up once it is flipped. But that is part of the challenge!

My nephew loved the robot.

I have learned more about electronics. Not too much, but enough to modify the racing parameters 🙂

I finally put my 3D printer to good use

I had a great time with my daughter setting it up.

The B-Robot is great and make many fun

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.

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

B-Robot is a nice toy.
But with my shipment is something going wrong.
The shipment takes more then 10 days, okay, its Corona time.
The rubber ring for the wheels are to O-Ring shown on the picture are shown flat rings. So I had to print new wheels.
On the control board the pins for the motor cabel are sold flat on the board. This is very unfirm. I was a little awkward and have to resold the two plugs. Please use holes for the pins in the future. Parts of the conducting path are going away with the connector pins and it was very tricky to find positions for solding.
Finaly the servo is total junk. It do nothing but vibrate. I open it an found that there is no connection between gear and potentiometer. I use an other one out of my spare box.
The robot with the android app works fine now. I would like to have more information for the use of additional sensors and autonomical steering.

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

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

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!

Thanks for the feedback! please contact us at info@jjrobots.com for a servo replacement. Regarding the motor headers, we have improved the PCB with wider contact pads. They are now capable of sustaining way more stress than before.
 We have changed to rubber (nitrile) O-rings as they provide way more grit to the wheels than the previous material. Assembly guide updated ;-)

Keep doing what you do, jjRobots

I had a few problems getting the b-robot to balance properly, and they were sorted in 2 ways: first, ordinary general-purpose AA batteries don\’t have the power reserve to make this work properly (I ended up with a 3-cell LiFe battery pack), and one motor connector fell off the Devia board (immediately replaced by jjrobots with no quibbling at all). Now it runs well!

Nice little projekt, it works fine. I had a lot of fun with building and playing.

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

I 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.

Great Product. Received in time and a superb after support by jjrobots

A 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.

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.

Added my customised bumper!. Great feature jjrobots 😉

I have modified the frame by myself as this robot make it possible. Great OPEN SOURCE robot guys!

100% OPEN ROBOT, 200% fun. I thought it will be hard to set it up but I actually enjoyed it

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.

Thank you very much for this awesome Robot!!!

Very fast shipment!
Very nice App for Android!
The Code is very good!
Everything is perfect!

Thanks

Very good product the quality. thank you very much! quickly reached!

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

We are having some fun racing with two of these robots. 😉 Great product

Thank you for this. Everything perfect *****

Extremely funny robot. I have added some custom parts to it and keeps the balance. Thanks

I love your OPEN SOURCE robots (and the way they are designed).
I have been using this Robot without any issue so far. 5 stars!

Excellent product, complete, easy to assemble and open to firmware and software upgrade / customization. Very fun and educational! A++++

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!
