Free robotics for kids and robotics for beginners in 30 short lessons — the parts of a robot, sense → think → act, wheels and motors, gear ratio for kids, wheel distance, sensors, a line follower robot, grid programs, loops, if / else and debugging, with fresh questions every time. Each lesson has a clear method, a worked example, “Show me how” help, a 20-question test, a badge, printable worksheets with answers and free certificates — and no robot kit is needed.
🦾 Quick check: What is a robot?
Each lesson has the idea, a worked example, unlimited practice with “Show me how”, a 20-question test and worksheets. Pass a lesson’s test to earn its badge; pass every lesson in a part to earn that part’s certificate (sign in to keep badges, certificates and progress).
Ages 8–10 — what a robot is, sense → think → act, the parts of a robot, robot batteries, robots in daily life, factories, space and hospitals, robot safety, robots and people, and a Part 1 test.
Ages 10–13 — wheels, tracks and legs, DC and servo motors, gears, gear ratio sums, wheel distance, robot sensors, the ultrasonic distance sensor, light sensors for line following, the gyro and turning, and a Part 2 test.
Ages 11–16 — moves on a grid, loops and shapes, if / else with sensors, line-follower programs, the state of a robot, debugging, stopping in time, competitions and teamwork, robot and AI ethics, and the final test.
Robotics is the science of machines that sense the world, think with a program and act on their own. In Part 1 children learn what makes a robot different from a simple machine, the sense → think → act loop, the parts of a robot (frame, motors, sensors, controller, battery, wheels and gripper), how long a battery lasts, where robots work — at home, on farms, in factories, in space and in hospitals — how to stay safe around robots, and which jobs suit robots and which suit people. In Part 2 they choose wheels, tracks, legs or propellers for the ground, steer a two-wheeled robot, set servo angles, see how gears trade speed for strength, work out gear ratios with teeth × turns, find how far a wheel rolls (circumference × turns, with π = 22/7), and learn the touch, light, ultrasonic distance and gyro sensors, including the light sensors of a line follower robot. In Part 3 they read and run simple robot programs: moves on a grid, loops that draw squares and other shapes, if / else for obstacle avoiding, line-follower rules, the state of a robot after a program, debugging, stopping in time, robot competitions and teamwork, and the ethics of robots and AI — safety, honesty and privacy. Everything works on paper and screen; no robot kit is needed.

Robotics for kids teaches what robots are and how they work — the parts of a robot, sense → think → act, motors, gears, wheels and sensors — and how to read and write simple robot programs with moves, loops and if / else. This free robotics for beginners course has 30 short lessons with practice, tests and worksheets.
रोज़ 10–15 मिनट एक छोटा पाठ करें। पहले तरीका और उदाहरण साथ पढ़ें, फिर 10 सवाल हल करवाएँ और गलत जवाब पर “Show me how” दबाएँ। रोबोट किट ज़रूरी नहीं है — सवाल, ग्रिड प्रोग्राम और गियर के हिसाब कागज़ और स्क्रीन पर ही होते हैं। अगर घर पर कुछ बनाना हो तो सिर्फ़ छोटे बैटरी वाले किट से, किसी बड़े की निगरानी में।
Ages 8 to 16. Part 1 (what robots are) suits ages 8–10, Part 2 (how robots move and sense) ages 10–13, and Part 3 (programming robots) ages 11–16. Older children can start anywhere and revise with the tests.
No. Every lesson, test and worksheet works without any hardware — children learn the ideas, do the gear and wheel sums and read simple robot programs on screen and paper. For more hands-on style practice, try our free Block Coding for Kids puzzles (talentjr.in/block-coding-for-kids), where children program a robot on a grid, and Electronics for Kids (talentjr.in/electronics-for-kids) for circuits, motors and sensors. A small battery-powered kit is a nice extra with an adult, but it is not needed.
Yes, when done the safe way. This course is learnt on paper and screen. If your child builds a robot, use a low-voltage battery kit with an adult nearby, switch it off before fixing anything, keep fingers and hair away from wheels and gears, and charge batteries on a hard surface.
A line follower robot drives along a black line using light sensors. Black reflects little light and white reflects a lot, so a low reading means the sensor is over the line. With one sensor on each side, the rules are: left sees black → turn left, right sees black → turn right, both white → go forward. Lessons 18 and 24 teach both the sensors and the program.
With teeth × turns: every tooth the driver pushes moves one tooth of the driven gear. A 10-tooth gear turning 6 times pushes 60 teeth, so a 30-tooth gear turns 60 ÷ 30 = 2 times. The gear ratio is driven teeth ÷ driver teeth (30 ÷ 10 = 3), so the big gear turns 3 times slower but stronger.
Sign in and pass the 20-question test of a lesson (16 or more right) to earn its badge. Pass every lesson of a part — Part 1 is lessons 1–10, Part 2 is 11–20, Part 3 is 21–30 — and you get that part’s certificate, with a code anyone can check.
Yes. All 30 lessons, practice, tests, worksheets, badges and certificates are free. Classes with a TalentJR teacher (online or at home) are paid — request a call back for fees.
