Solution Overview
Problem
Current methods for teaching programming to children are challenging due to the abstract nature of programming concepts, requiring literacy and motor skills, and often fail to engage young learners, leading to high dropout rates in programming courses.
Innovation Solution
An interactive system comprising RFID-tagged tiles and an interactive robot that responds to voice commands, allowing children to create paths and solve problems through sequencing and programming, incorporating movement, sound, and question-based interactions, thereby introducing computational thinking concepts in a fun and relatable manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If programming concepts are taught using traditional methods (visual blocks, tangible blocks), then children can learn sequencing and programming, but the abstract nature of programming and requirement for literacy/motor skills makes it difficult and unengaging for young children
Solution Approach 1:
The patent replaces traditional visual block-based programming interfaces (requiring fine motor skills and literacy) with voice command-based interaction. Children speak natural language commands to program the robot, eliminating the need for dragging blocks or reading code, thus substituting mechanical interaction with speech-based interaction that is more accessible to young children.
Solution Approach 2:
The patent introduces RFID tags as intermediaries between the physical environment and the programming system. Each tile contains an RFID tag that automatically identifies the tile's position and function, allowing the robot to understand commands without requiring children to program complex logic. The RFID technology mediates between the simple voice commands and the robot's navigation system.
2Reliability
If programming is introduced to children early, then they have time to develop problem-solving skills and logical thinking, but programming is perceived as too difficult and not interesting enough
Solution Approach 1:
The patent inverts the traditional approach by having the robot follow the child's voice commands rather than the child manipulating programmed blocks. The child speaks natural language instructions like 'move forward' or 'turn right,' and the robot executes them, reversing the control relationship to make programming more intuitive and engaging for young children.
Solution Approach 2:
The patent changes the interaction modality parameter from visual-tactile (block manipulation) to auditory-vocal (voice commands). This parameter change makes programming accessible to children who may not have developed fine motor skills or literacy, while maintaining the ability to teach sequencing and logical thinking through structured voice commands.
3Ease of operation
If visual methods are used to teach programming through blocks and drag-and-drop interfaces, then children can create programs, but it requires literacy and motor skills that young children may not possess
Solution Approach 1:
The patent replaces the mechanical block-manipulation interface with a speech-based interface. Instead of requiring children to physically handle blocks, drag them, and arrange them in sequences, they simply speak their instructions to the robot, which automatically interprets and executes the commands. This substitution eliminates the harmful factor of requiring developed motor skills and literacy.

AI summary
The present disclosure discloses an interactive system for teaching sequencing and programming to children. In some embodiments, the interactive system comprises a plurality of tiles organisable to form a structural pattern, wherein each tile comprises an RFID tag storing at least a pre-defined command corresponding to a first action and an identifier associated with a second set of actions, and an interactive robot. In some embodiments, the interactive robot when placed on the tile is configured for, receiving a voice command from a user, reading at least the pre-defined command and the identifier from the RFID tag associated with the tile, comparing the command received from the user and the pre-defined command, and performing one or more actions from among a third set of actions based on a result of comparison.
