Early years: hands-on tools first

Robotics can begin before children read. Writing in Early Childhood Research & Practice, Marina Bers describes the TangibleK programme, in which kindergarten children build robots and program their behaviour, and argues that with age-appropriate technologies, curriculum and teaching, young children can take part in programming and robotics in ways consistent with developmentally appropriate practice. She notes research showing that children as young as 4 can understand basic programming concepts. In practice that means physical blocks, cards or buttons rather than screens, short sessions and plenty of talk. Bee-Bot, Cubetto and Kibo 21 are among the early-years robots on this site worth comparing.

Ages 5 to 7: sequences before conditions

Order the concepts carefully. In Computers & Education, Bers and colleagues followed three kindergarten classes, analysing 53 children aged 4.9 to 6.5 years. Many scored highly when programs used only action instructions, but achievement was comparatively lower once control flow instructions or sensors came in, and an 'If' instruction proved easier than 'If Not'. For infant classes, spend time on sequencing and debugging simple routes before adding repeats, sensors and decisions. Choose a robot that lets a child see each step run, and plan activities where pupils predict what a program will do, test it and fix it in pairs, so the teacher can hear their reasoning.

Ages 7 to 11: blocks, sensors and teams

Junior pupils are ready to connect code to sensors and to work in small teams. Block-based programming suits this stage because children can build loops and conditions without wrestling with syntax. On this site, the Micro:bit, Makeblock mBot2, Sphero BOLT, VEX GO and LEGO Spike Prime are among the kits to compare for junior classes; check each maker's own age guidance. Look for activities where the robot must react to light, distance or touch, since that is where earlier work on sequences pays off. Plan for groups of two or three per robot, give each pupil a role such as builder, coder or tester, and rotate roles.

Secondary school and university

Teenagers can move from blocks to text-based languages such as Python, and many enjoy the pressure of a competition or a design brief. Clubs can compare VEX IQ, the DJI RoboMaster EP Core and the Robotis Darwin Mini on this site, while sixth-form and undergraduate students may be ready for research platforms such as TurtleBot 3, TurtleBot 4 or NVIDIA JetBot. Match the platform to the qualification or course outcomes you must deliver, not to what looks most impressive at an open evening. Keep a simpler robot in reserve for students who join late, return after a break or need to rebuild confidence before tackling harder projects.

Common questions

Can a three-year-old use a coding robot?

Some early-years robots are designed for preschool use, but check the maker's age guidance and toy safety markings first. At three, keep sessions short and led by an adult, focusing on moving the robot forwards and turning, and expect play and talk rather than independent programming.

What robot should a teenager start with if they have never coded?

Start with a kit that offers both block and text programming, so early success comes quickly and the move to Python feels natural. A clear set of projects and an active user community matter more than advanced sensors at the beginning.
