Drag-and-Drop Programming
Build programs visually by connecting colorful blocks — just like building with LEGO
Shape-Based Logic
Blocks only connect when they make sense — preventing syntax errors and teaching proper program structure naturally.
Instant Execution
Click run and watch your robot respond immediately. See the connection between your blocks and robot actions in real-time.
Blocks-to-Code View
Toggle to see your block program as Python or C++ code. Learn text-based coding naturally while using blocks.
Color-Coded Categories
Motion blocks are blue, sensor blocks are green, logic blocks are orange — find what you need at a glance.
Unlimited Undo/Redo
Experiment freely! Every action can be undone. Students learn best when they're not afraid to try new things.
Perfect for Young Learners
Designed with developmental stages in mind
