Robots Word Search

Build-a-robot, in one grid

Robots fascinate just about everyone, and this word search gathers the parts and ideas that make them tick. You'll be finding the robots themselves — ROBOT, ANDROID and CYBORG — the parts inside, from the MOTOR and SERVO to the CIRCUIT and SENSOR, and the science that brings them to life, from the ACTUATOR to a clever MECHANISM.

Each puzzle pulls a fresh selection from the list, so the build changes every time you play — gentle on Easy, and a longer-word challenge once the diagonals and backwards words appear on Hard.

Nuts, bolts and circuits in the grid

The grid gathers everything that goes into building a robot. There are the robots themselves — the ROBOT, ANDROID, CYBORG, HUMANOID and old-fashioned AUTOMATON — and the moving parts that make them go: the MOTOR, SERVO, GEARS, JOINT, ACTUATOR and the whole MECHANISM. There's the electronics inside — the CIRCUIT, SENSOR, WIRES, ANTENNA and BATTERY — plus the words of building and brains: METAL and WELDING, a guiding PROGRAM, the CONTROL system, a BIONIC limb, a LASER and a humming MACHINE.

How a robot senses and moves

A robot works in a loop that's a bit like the way you do: sense, think, act. First a SENSOR gathers information — measuring light, distance, heat or touch, the robot's version of eyes and skin. Then a PROGRAM running on a tiny computer decides what to do. Finally an ACTUATOR — often a MOTOR or SERVO turning GEARS and JOINTS — actually moves the arms, wheels or legs. Take away any one of those three and the robot just sits there.

The word 'robot' is surprisingly young: it was coined in a 1920 Czech play by Karel Čapek, from a word meaning 'forced labour'. Today real robots do the jobs we'd rather not — exploring Mars, welding cars, or going where it's too dangerous for people — and most look nothing like the HUMANOID robots of films; many are just a single clever arm. Robotics blends engineering, coding and design, which makes this puzzle a brilliant fit for a robotics club, a 'how machines work' topic or a design-and-technology project.

Great for a STEM topic

It's a great fit for a robotics club or 'how machines work' topic — many words are short, and Easy mode uses a small grid with no diagonals or reverse words. Play online, print a PDF pack, or use Make Your Own to build a grid from your own robotics words.

Frequently asked questions

What's in the robots word search?

Robotics words — robot, android, cyborg, sensor, motor, circuit and more. Each puzzle uses a fresh selection.

Does it cover the parts inside a robot?

It does — the robots themselves (the ROBOT, ANDROID and CYBORG), the parts inside like the MOTOR, SERVO, CIRCUIT and SENSOR, and the science that brings them to life, from the ACTUATOR to a clever MECHANISM.

Is it good for a STEM topic?

Great fit for a robotics club or 'how machines work' topic. Many words are short, and Easy mode uses a small grid with no diagonals or reverse words.
