About JJrobots:
   We love robots, DIY and funny science. JJROBOTS aims to bring Open robotic projects closer to the people by providing hardware, good documentation, building instructions+code, "how it works" info and a lot of fun!

B-ROBOT (a remotely controlled self balancing robot)


B-ROBOT is a remotely controlled self-balancing arduino robot created with 3D printed parts. With only two wheels, B-ROBOT is able to maintain its balance all the time by using his internal sensors and driving the motors. You can control your Robot, making him move or spin,  by sending commands via a Smartphone, Tablet or PC while it maintains its balance.


iBoardBot. The internet controlled drawing robot

The internet controlled drawing robot.

An internet controlled robot capable of writing+drawing (and wiping!) on a glass surface.

The iBoardbot is a robot connected to the internet capable of writing texts and drawing with great precision. Also, it can erase in a quick and effective way.

Send to your iBoardbot your information from any part of the world. As it has a multi-user interface you can also play and challenge your kids, use it as a collaborative notice board or as a twitter wall in your shop window. Have fun and enjoy learning how to assemble your iBoardbot!

Air Hockey Robot (3D printer hack)

Based on the original Air Hockey robot, this new Air Hockey Robot EVO is much easier to set-up and deploy. Controlled by your own smartphone using the freely available APP

A challenging robot, perfect to have fun and learn robotics at the same time

It is faster, easily modifiable and shares the electronics and ancillary elements with others jjRobots like the iBoardbot, B-robot EVO. Sphere-O-Bot (and more to come!)


StarTRACKER (night Sky photography)

The StarTRACKER is an equatorial mounting for night sky photography.


To take long-exposure astrophotos of objects that are too faint to be seen, you will need a polar-aligned equatorial mounting that allows you to track the stars during their exposure to compensate the Earth's rotation.

JJrobots Shipping costs

We do not want to get any profit from shipment. Check it by yourself:

Sending a small packet with some jjROBOTS electronic from, for example, UK to Canada would cost less than 1,9 euros (1,39 pounds!).

Plot Clock: jjrobots version

plot clock jjrobots
We have been adapting the very popular Plot clock (from Johannes and with contributions from Kjetil Egeland) to the current jjRobots electronics (Brain Shield). The idea is to connect this new version of the Plot clock to internet allowing it to read the time from any internet clock (google/microsoft/nasa...any with a ntp service) and other info (local weather forecast, temperature...etc)...


blimpduino 2.0: updates

Hi everyone!

We are now moving the blimpduino project to the next stage: PCB manufacturing (mrobotics.io is working on it now. Thanks Jordi!) The electronics has passed all the tests and the Arduino CODE is 70%-ish done. I have to confess that this "robot" development is being quite exciting. The blimpduino 2.0 has been created with the primary goal of being suitable and capable of controlling as many balloons types as possible. No matter its size or shape.

First version of the blimpduino. And yes... you can control it touching your smartphone´s screen or just using a Bluetooth controller connected to the smartphone.


How many humans do you need to assembly a modern car? and other robotics things

Would you like to bet? How many humans are involved during the assembly process of a modern car? 10 - 100?


Happy 2017!

off road small That´s all we wanted to say. Happy 2017, stay safe this Xmas and have a very happy and very interesting 2017 😉

The "Outrageous Acts of Science" JJrobots episode will be launched on Discovery Science channel on Wednesday 27th July.

Guest Star: Air hockey robot. How it was made and other curiosities.

Hmm…a new project?

What is this? A hackable/ cool/ full of features/affordable 3D display?

Hi there!

We are working in something...cool 😉   Pretty sure you will like it.


New KIT: B-robot EVO

We have received some emails asking for this KIT:

A set that includes EVERYTHING. So, during the nights, we have been working hard in the dungeon finding the best possible stepper motors, servos, buttons... and creating and stocking this new KIT.

Everything is included, previously thoroughly tested so you only need to assemble it. 

Take a look at the video and watch how it behaves now!:                                                       

to the shop!
