Sparki is an affordable, easy to use, and fun intro to programming, electronics, and robotics. It is geared towards kids elementary-age and above, educators looking for an easy intro to robotics, parents eager to find something affordable but educational and fun, DIY enthusiasts, and more. It is simple enough for beginners, while being feature-packed enough to be a must-have for pro-users. Sparki is your chance to have your very own robot, completely open source and available to do your bidding.

Applications :

Be a toy or present for your children;
An easier way to learn Arduino;
Be a good tool of education for your children ;
Be a good way of education on your class
An amazing secondary development platform for geekers,hackers

Specification :

Completely Arduino-compatible, the controller use the Arduino Leonardo
Low cost, but much to play;
No assembly required;
A lot example codes for test;(Some advanced concepts may not offered,but you may find it in sparki community)
Wireless control through bluetooth;
And So many sensors:
1x Ultrasonic distance sensor (get distance from Sparki to walls/objects)
1x 3-Axis Accelerometer (pick-up detection, fall detection, hill climbing)
1x 3-Axis Magnetometer (sense the magnetic field around Sparki, coordinate with accelerometer to detect compass heading)
3x Light-sensing phototransistors (light following, darkness seeking)
5x Line-following and edge detection sensors (mazes, line follow, sumo)
1x 128×64 Graphic LCD
1x RGB LED (RGB = generate any color!)
1x Buzzer (beeping, booping, and musical tones!)
1x IR Transmitter (like your TV remote control)
1x IR Receiver (like your TV)
1x IR Remote control (lots of buttons to control Sparki with)
1x TTL Serial port for expansion (talk to an Arduino/Raspberry Pi)
1x Port for Bluetooth Serial Module (not in all rewards)
Powered by 4xAA batteries (rechargeable or alkaline)
2x Geared stepper motors (precise, measured movement down to millimeters/ sub-degrees)
Marker holder for drawing
