A 32-bit color-screen controller, motors with built-in encoders, plug-and-play high-precision sensors, and brand-new structural parts for building 3D mechanisms — an advanced robot design and programming kit for elementary students aged 7–10.
Screws and nuts replace the traditional snap-fit blocks, so kids "screw together" every robot like real mechanical assembly. Graphical programming plus AI model training makes robots that can see, hear, and interact. Four stages and 80 regular lessons run through a complete story line — from tightening the first screw to independently designing a full game.
From the first tightened screw to gears turning and the program running — one video shows the full experience.
ShengTong Roborobo AI MCU 5.0 is a graphical programming robot course designed for ages 7–10. Students use structural parts, screws and nuts, gears, and electronic components to assemble movable, sensing, programmable robots from scratch, understanding mechanics and logic through hands-on building and debugging.
The hardware is fully upgraded: the controller is upgraded to a 32-bit color-screen processor; motors with built-in encoders support stepless speed control and precise position control; sensors are fully iterated; structural parts have multiplied, with new five-sided beams, building beams, and other 3D components enabling complex mechanical structures such as gear drives and linkages.
The course runs through a complete story line, with a six-step closed-loop teaching method paired with AI interactive courseware. Programming knowledge spirals upward with smoothly increasing difficulty, while the 3STC three-dimensional nine-element framework runs throughout — students learn not only programming, but engineering thinking and comprehensive literacy.
The controller is the brain, motors and servos are the muscles, sensors are the senses, and the lithium battery is the heart. Anti-reverse ports make plugging in foolproof.
High-performance 32-bit processor at 168 MHz with 8 MB RAM for efficient and stable operation; 2.4-inch full-view HD touch screen with built-in Chinese font library, so program status is visible at a glance.
Rechargeable lithium battery solution replaces frequent dry-cell replacement. It keeps running lesson after lesson, ensuring battery life and a worry-free classroom.
Metal-gear high-torque motor supports forward, reverse, and braking. Built-in encoder closed-loop control supports -100 to 100 stepless speed regulation and precise position positioning, resisting damage from stall and reverse.
An integrated servo unit combining motor control, servo drive, and bus communication for robot joints, steering, and angle control, with more precise angles and better durability.
A line-following sensor that distinguishes light and dark colors, with anti-sunlight interference design and automatic threshold calibration through field scanning — a reliable sensing unit for line-tracking tasks.
Pairs with the 2.4G wireless module with one click for long-distance real-time control of your own robot, so competitive and racing games can start anytime.
Lets robots "see." Supports color recognition, QR code recognition, and other vision tasks. Students can collect samples and train their own recognition models, bringing real large-model AI applications into the classroom.
Lets robots "understand" sound: supports voice classification and command recognition, so a single spoken command can trigger an action, making human-robot interaction more natural.
Ten AI function modules covering visual recognition, voice recognition, and QR code recognition — all hands-on in the classroom.
The course provides more than 10 AI function modules covering visual recognition, voice recognition, and QR code recognition. Students do not just "watch the teacher demo AI"; they collect samples, train models, and test recognition effects themselves, understanding firsthand how AI learns.
Train 4 gesture samples and use different gestures to control the fan at low, medium, high speed, or stop.
Collect faces, train a model, and make the door "know" you — a real large-model AI case study brought into the classroom.
Posture recognition, voice classification, text classification… more AI functions and robot projects are continuously updated.
Screwdriver and socket wrench work together to lock structural plates, five-sided beams, motors, and servos step by step into a whole.
Aligning holes, holding the nut steady, and controlling force — the very act of tightening screws trains hand-eye coordination and fine motor skills.

Additional 10 / 15 / 20 / 35 / 55mm bracket screws, nuts, lock nuts, and washers meet fastening needs for plates of different thicknesses.
A 3D structural system of five-sided beams, building beams, corner connectors, and gear sets turns projects from square frames into real machines that can drive, walk, and grab.
Spur gears and double bevel gears combine to achieve acceleration, deceleration, and direction change.
Single / double accelerationConvert rotation into reciprocating and swinging motion — the basis of bipedal walking and robotic arms.
Rotation → ReciprocationTurns uniform rotation into regular up-and-down bouncing.
Rotation → LiftTires, caster wheels, and track pieces support both wheeled and tracked chassis.
Wheeled · TrackedMulti-directional holes on five-sided and building beams form a stable 3D skeleton.
3D · StableMultiple shaft sizes, bushings, and bearing sleeves cover every joint in the drive chain.
Drive precisionFixed and movable pulleys change force direction and magnitude — the secret of crane force saving.
Force saving · RedirectRubber bands store elastic potential energy and release it instantly — how ejection mechanisms fire.
Elastic potentialDrag blocks to build programs, compare with Python code side-by-side, and verify ideas with virtual simulation.
The Scratch-style graphical programming interface is more accessible for elementary students: start from effect analysis, then go through step decomposition, instruction combination, and download-debugging in a complete closed loop. Python code is displayed side-by-side to lay the foundation for future code learning; virtual programming and simulation allow verifying ideas before deploying to hardware.
Stage 1 and Stage 2 kits together contain more than 590 parts in 119 specifications, from a single screw to a five-sided beam.
The full course has 4 stages and 80 regular lessons, with 4 lessons per unit and one theme story per unit. The first stage has 5 units and 20 lessons with full outlines below — each lesson clearly states what to build, what to program, and what knowledge is learned. Stages 2–4 are coming soon.
"Jumping Elf" brought cheers. In class, students assembled cams and linkages and used touch to make it jump on press, seeing uniform rotation turned into up-and-down motion by a cam.
The rotor must spin and the signal light must flash — one program cannot handle both. Students assembled blades and gear sets, used multi-tasking to run both at once, and understood rotor spin creates lift.
Same motor, why is someone else’s car faster? Students challenged multi-stage gear acceleration box meshing, used conditional loops and motor speed control to transfer power to wheels, experiencing gear acceleration and torque trade-off.
Whipping egg whites is tiring and delicate. In class, students used gear acceleration to increase speed, reinforced the body, and used nested dual branches to switch between stirring and whipping, understanding the basis of high-speed whipping and low-speed stirring.
Crossing asteroid belts, locking targets, and shooting accurately — a fighter must do three things at once. Students built the body, turret, and wheel set, used a game main loop with multi-branch logic, and mastered encoder distance control.
