The Scribbler S3 the perfect place for students and teachers to begin their STEM/STEAM journey.

The robust, easy-to-use S3 robot is simple enough to set up in minutes, and is powerful enough to teach engaging activities throughout the school year. Programming, robotics, and even integrating math and art are all possible with the S3.


The BlocklyProp online tool is the S3 robot’s primary programming environment. Its interlocking blocks with readable text let beginners build programs in an intuitive, visually logical way. The BlocklyProp tool exposes the S3’s encoders to provide control over distance and speed for all possible types of movement.

Pre-made blocks support all of the S3 robot’s sensors, motors. In addition, blocks are included for select accessories that plug into the S3’s Hacker Port. Customize your S3 by connecting a Parallax Standard Servo, PING))) Ultrasonic Distance Sensor, or even an XBee RF module if you are an adventurous hacker willing to open the case.
