Screen-free AI coding toy for kindergarten 4-6 years

　　1. Core Specifications and 4-6-Year-Old Adaptability

　　This screen-free AI coding toy is engineered for kindergarteners aged 4-6, blending tangible coding modules with AI guidance to introduce foundational programming logic—no screens, no text, and optimized for this age group’s developing fine motor skills and logical reasoning:

　　Key Performance Indicators

　　AI Coding Logic: Teaches age-aligned programming concepts—sequence (step-by-step order), simple loop (repeat 2-3 times), and basic condition (if obstacle, then turn)—adapting difficulty: e.g., 4-year-olds start with 2-step sequences; 6-year-olds progress to "loop + condition" combinations

　　Safety & Durability: Food-grade ABS plastic (modules), BPA-free silicone (toy body), ASTM F963-23/EN 71-3 compliant (no toxic chemicals/choking hazards: modules ≥3cm diameter), drop-tested from 1.5m (classroom daily use), rechargeable via USB-C (5-hour battery life)

　　Usability for 4-6-Year-Olds: Large, easy-grip modules (non-slip surface), 12+ detachable coding blocks (color-coded by logic type: blue=sequence, yellow=loop), and AI "help prompt" button (kids press to ask for guidance—no adult assistance needed)

　　Structural & Kid-Centric Design

　　Features a robot-shaped main unit (14×9×6cm, lightweight 240g) with a top "coding tray" (magnetic, holds modules in order) and AI sensors that instantly recognize module placement. No screens—all feedback is via voice and LEDs, avoiding eye strain and keeping focus on hands-on logic building. Comes with 5+ "mission cards" (e.g., "Find the toy car," "Avoid the block obstacle") that sync with AI: kids pick a mission, and AI guides them to code a path to complete it. The rounded design has no sharp edges, and modules are labeled with kid-friendly icons (no text) to support pre-literate learners.

　　2. Core Advantages for 4-6-Year-Old Coding Learning

　　Screen-Free Design Turns Abstract Coding into Tangible Play

　　Unlike tablet-based tools, it uses physical modules to make programming logic concrete: 4-6-year-olds arrange "forward + loop (2x) + turn" modules on the tray, and the toy robot executes the path—AI explains, "You told me to walk twice, then turn! Great sequence!" This bridges abstract "logic" to real action, matching the age group’s "learn-by-doing" style.

　　AI Guides (Don’t Dictate) to Build Problem-Solving Skills

　　The toy’s AI avoids direct answers, instead asking guiding questions to foster critical thinking: if a child’s "obstacle + forward" code fails, AI prompts, "Oops! We hit something—what if we turn first, then go forward?" For 6-year-olds, it adds complexity: "You used a loop! Do you want to repeat 2 or 3 times to reach the goal faster?" This aligns with 4-6-year-olds’ growing ability to analyze and adjust their actions.

　　Age-Aligned Logic Prepares for Future Learning

　　It targets logic skills 4-6-year-olds can master: sequences (3-4 steps), loops (repeat 2-3 times), and simple "if-then" conditions (e.g., "if red light, then stop"). These build a foundation for later coding while avoiding frustration—no complex syntax or text, just hands-on arrangement and immediate feedback.

　　Supports Both Independent Play and Group Collaboration

　　Modules are easy for 4-6-year-olds to use alone (building independence) or share in groups of 2-3 (fostering teamwork): kids take turns adding modules to code a shared mission (e.g., "Help the robot find the teddy bear"), and AI encourages turn-taking: "Now it’s Leo’s turn to add a module—what do we do next?"

　　3. Practical Kindergarten Application Scenarios

　　Classroom Group Missions: A teacher gives a "treasure hunt" mission—3 kids work together to arrange modules ("forward 2x + turn + forward") to guide the robot to a hidden block. AI comments on their teamwork: "You all picked different modules—together you made a great path!"

　　Individual Skill Building: A 5-year-old practices loops independently: they add a "loop (3x) + forward" module, and the robot walks 3 steps repeatedly. AI asks, "Do you want to make it walk 2 times instead? Let’s change the loop!"—helping them experiment with logic.

　　Home Parent-Child Play: Parents and kids co-create a "obstacle course" (using books as barriers). The 6-year-old codes "forward + if obstacle, then turn," and the parent helps adjust module order—AI says, "You and your grown-up made me avoid the books! Teamwork works!"

　　Outdoor Exploration: During playground time, kids code the robot to "walk to the slide"—they arrange "forward + turn + forward" modules, and the robot moves across the grass. AI links to real-world logic: "You used directions to help me get to the slide—just like how we follow maps!"

　　4. Usage Recommendations for Kindergarten & Home

　　Age-Specific Skill Progression:

　　4-5-year-olds: Start with 2-3 step sequences (e.g., "forward + turn") and simple loops (repeat 2x); use mission cards with clear visuals (no text)

　　5-6-year-olds: Introduce "if-then" conditions (e.g., "if obstacle, then stop") and longer sequences (4-5 steps); encourage them to create their own missions (e.g., "Code the robot to my chair")

　　Classroom Group Tips: Assign 15-minute rotation times (4 kids per toy) to avoid waiting; use the toy’s "group mode" (AI prompts each child to add one module) to ensure equal participation

　　Safety & Maintenance: Clean modules with baby-safe wipes (plastic/silicone resists stains); store modules in the toy’s built-in compartment to prevent loss; charge the toy overnight (USB-C connector is kid-safe—no exposed pins)

　　Curriculum Integration: Pair with kindergarten math (count loop repetitions: "We repeated forward 3 times!") and spatial skills (discuss "left/right turns" while coding) to link coding to existing learning goals
