The Parallax Scribbler S3 is one of the most overlooked and underrated robots on the market.  It comes fully assembled with line sensors for following lines, proximity sensors for detecting objects, light sensors capable of isolating the brightest light in a room, and wheel encoders that make accurate movements possible.  Now, RobotBASIC makes the S3 even better and much easier to use.  Downloading and installing the FREE RobotBASIC Robot Operating System for the Scribbler (RROSS) and adding a Bluetooth adapter through the S3’s hacker port allows RobotBASIC programs to immediately (no downloading required) control the robot’s movements and access its sensor data.  You can even develop your algorithms using RobotBASIC’s integrated simulator as discussed in the new book RobotBASIC Projects for the Parallax Scribbler S3, available on Amazon.com.  Those wanting more power than the S3’s native sensors can expand the robot with a custom 3-Ping mount and a beacon detector from RobotBASIC (no soldering required).  Complete information is available from www.RobotBASIC.org.

$29      Ping Mount Kit

This package includes a 3D-Printed mount for 3 Ping sensors (Pings not included), 3 Ping cables, cable ties, a protoboard, and a small weight (shown on the back of the S3).  The weight is not required but it makes the S3 more stable after adding the Ping sensors.
