“Create hundreds of your own droids with three levels of challenge: Jedi apprentice, Jedi Knight, or Jedi Master. Use the "Micro Scout" Lego microcomputer for the brain of your droids. Use the built-in light sensor, motor and sound to bring your droids to life. Create... More familiar Star Wars droids like R2-D2 or use the Force to create droids of your own.”
Brickset
“It was a great idea for LEGO to use their new Star Wars license with the robot, or droid building of Mindstorms. And it was also a good way to introduce younger builders to LEGO Mindstorms. Though for older builders, it's best as an expansion for the Robotics Invention... More System. Getting it now isn't necessary, but for younger builders who want to build robots and likes Star Wars, it's perfect.”

About Mindstorms Star Wars

LEGO Mindstorms Star Wars, specifically known as the "Droid Developer Kit," was released in 1999 and combined the programmable robotics of LEGO Mindstorms with the beloved Star Wars universe. Set number 9748, the Droid Developer Kit, allowed users to build and program Star Wars droids. One of the most iconic builds from this set was a version of R2-D2. The kit used the RCX programmable brick (similar to other early Mindstorms sets) as the "brain" to control the droids and came with specific building instructions and programming tasks tailored to the Star Wars theme. It provided fans a unique blend of LEGO robotics and Star Wars creativity.
