TinkerBlocks: Code, build, and drive!

Abstract

Tinker Blocks is an educational tool designed to introduce children to programming concepts in an engaging and interactive way. By placing coding blocks (MOV, IF, LOOP) on a grid board, children create sequences that control a programmable car. A camera captures the grid’s layout, and a Raspberry Pi processes the image, interprets the program, and executes the commands— allowing the car to move, turn, or draw. This hands-on approach helps children understand programming concepts like branches and loops while improving problem-solving skills. The project includes three game modes: Race Mode, where children program the car to navigate a path efficiently; Shape Drawer, where they use a pen-equipped car to draw shapes and receive accuracy scores via machine learning; and Free Mode, which allows open-ended exploration. The car is equipped with sensors, encoders, and a servo-controlled pen for precise movement. An LCD screen provides real-time feedback and controls. The development process combines hardware and software integration. Image processing detects block positions, microcontrollers handle motion, and machine learning assesses shape accuracy. Unlike Scratch or LEGO-based tools, which rely on digital interfaces or structured kits, Tinker Blocks provides a fully physical coding experience, bridging the gap between abstract programming and real-world execution. Children see their code directly translated into movement, offering a more intuitive and engaging way to learn programming. Tinker Blocks makes coding accessible and fun by turning programming into a game, helping young learners develop logical thinking through interactive challenges.
