Awesome Open Source Robots
$20
This is the motor used in every jjRobots Project. You liked the motors which came with your kit and want another pack of two? Did you like its sturdiness / easy plug-in connector (forget to solder every time you have to change the cable length) ? This is the perfect stepper motor for MAKERs and Robots enthusiasts.

A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil. Here are some of the driver’s key features:
This product ships with all surface-mount components—including the A4988 driver IC—installed as shown in the product picture.
This product ships individually packaged with 0.1″ male header pins included soldered in.
The Arduino Leonardo is a microcontroller board based on the ATmega32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

JJrobots´s Brain SHIELD. Created to simplify the set up and integration of all the different devices involved in the jjrobots projects.
This SHIELD has:
OPEN robots you can create with this Brain Shield:
NOTE: There are FULL ROBOT KITS ready to be sent to you in the SHOP . Save the hassle of getting all the components from different sources and support jjRobots getting a KIT!
Create very different OPEN SOURCE robots using the same electronics and ancillary elements. Everything can be modified, Hacked and customised!
STEM education robotic KIT: In addition to being fun, the MOST AWESOME ROBOTIC STEM KIT engage beginners and advanced students and incorporate many of the fundamental STEM concepts providing a learning platform that everyone enjoys
Fight battles with your remotely controlled B-robot, play with your torch from 50 meters away, send messages to your friend using the Iboardbot!, paint balls/eggs using your own pens or…create your new awesome robot from scratch!
Do you think you can improve or hack any of these robots? Do it! They are OPEN SOURCE robots, so all the info,know how and code is available for everyone. Share the knowledge! (and take a look at the JJrobots FORUM)
This is a remotely controlled torch pointer (can be changed for a Laser pointer). Can be moved from your smartphone using the JJrobots FREE app available in Google Play or using OSCtouch (or equivalent OSC software).
NEW: control your robot using the FREE JJrobots google APP (android devices)!
This KIT includes:
Optional:
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.
*The above WebApp link does not belong to any real iBoarbot. Play with it as much as you want
The kit is easy to assemble in an hour or so, and only requires a couple of basic tools like screwdrivers plus internet access to control the iBoardbot
All you need to create your own IBoardbot. Just follow the assembly instructions in order to set it up (the glass of your choice can be added to the KIT as an option.See below). With this KIT you won´t have problems getting the right cables, power supply, belts, bushings, bolts…It is just assembling
OTHERS:
NOTE: There is an almost-fully assembled iBoardbot version. Your customised iBoadbot, with a coloured glass of your choice (Orange, green, white or yellow) Including cloud service. You will get what you see, a “Plug and Draw” robot!

The Sphere-O-bot is a friendly art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to a large duck egg (4-9 cm).
The robot is based on the original design of Evil Mad Scientist
The Sphere-O-Bot is a simple 2 axis drawing machine that can draw on most spherical surfaces. You can use it to decorate balls or eggs. This design also features the regular JJrobots electronics (the same we have used in all our robots). So you can create this robot or any other just simply printing new 3D printed parts and uploading the appropriate code.
The original idea belongs to Evil Mad Scientist
The frame was designed by Attila Nagy
The Sphere-O-bot is adjustable, and is designed to draw on all kinds of things that are normally “impossible” to print on. Not just eggs but ping pong balls, Christmas ornaments, light bulbs, and (yes) eggs (duck, goose, hens…).
The Sphere-O-bot frame was designed by Attila Nagy and slightly modified by JJrobots. The pen and egg motors are high-torque precision stepping motors, and the pen lift mechanism is a quiet and reliable servo (SG90) motor.
All you need to create your own Sphere-O-bot. Just follow the assembly instructions in order to set it up . With this KIT you won´t have problems getting the right cables, power supply, bolts…It is just assembling
