LEGO MINDSTORMS Sorter Arm
Just two motors?
Build, play, and learn with our LEGO MINDSTORMS Robot Inventor Sorter Arm! This clever robot can sort colorful balls (14mm) all by itself—just like magic! Thanks to a special design of the grabber, I could make it work using just two motors.
By getting this product, you’ll get step-by-step instructions (super easy to follow!) to create this amazing machine using your LEGO MINDSTORMS 51515 kit. Plus, you’ll discover three fun programs in Scratch:
- Basic Program: Watch it sort balls by color automatically.
- Intermediate Program: Choose the color to sort on the fly!
- Advanced Program: Give the robot up to three orders and watch it go to work.
The programs are documented using detailed screenshots and are available for download only with the business license. It’s so satisfying to watch the arm sort with precision! This is a perfect mix of fun and learning for curious builders of all ages.
