Description :
LEGO Mindstorms Robotics Invention System 1.5 (Set 9747), a foundational robotics kit designed for ages 12+ and featuring 717 pieces. This system includes the RCX programmable brick, sensors, motors, and assorted Technic elements used to build and program a wide range of functional robots. The set was part of LEGO’s early consumer robotics line, allowing users to create autonomous builds using the included software and hardware components. Box artwork features the classic blue lightning design associated with the Mindstorms 1.x era. PLEASE NOTE: I did not count the pieces, therefore I have no idea if it is complete.
