How Sphero Works

Sphero products have always had more magic than meets the eye. Our robots are approachable and simple to use, yet are packed with incredibly complex tech. Here’s the gist of the magic inside your ball, starting with the circuit board, then the motor and charging functions. Pretty much a Sphero 101 as to the “what does what and why”.

The printed circuit board (or PCB) is
what houses all of the electronics in your Sphero that process commands into actions. A Bluetooth chip within that board connects to your device, receives your commands, and sends them to the IMU, or Sphero’s brain, to process. Also built into the circuit board are the gyroscope and accelerometer, which detect your Sphero’s movements, acceleration, and turning, helping to keep it oriented and driving where you tell it to drive.

An electric motor turns the wheels that move your Sphero while the pressure
from a stabilizer on top allow the wheels
to move your robot, keeping it from going
in circles inside the ball. To keep Sphero’s tech sealed inside its shell, it uses inductive charging rather than wiring to the batteries inside. Place it on the base and it’ll charge right through the polycarbonate. Easy peasy.


The SPRK+ robot is your vehicle to discovery – just add imagination. Connect to the Sphero Edu app to learn programming, complete activities, and get inspiretod through connected play and coding. This app-enabled ball is just the start.

SPRK+ brings students together to engage in STEAM concepts, regardless of skill level, gender, interests, culture, language, or socioeconomic status. They are empowered across all grade and ability levels, from elementary to high school and special education. Students can work collaboratively or at their own pace thanks to the Sphero Edu app, and track their progress on individual or group work.

The robot and app teach K-12 students foundational programming by enhancing cross-curricular STEAM projects, but they also lay the foundation for problem solving, design thinking, creativity, and engagement.

Sphero robots are being integrated into all subject areas including STEAM. Young students are grasping early concepts of programming while fostering 21st century skills, whether they’re replicating the solar system, programming characters in a story, or painting geometric shapes with the robot. Students learn to think and act like engineers, exposing them to real world problems and the 4C’s (collaboration, communication, creativity, and critical thinking).
