Sense, think, act
Most classroom robots follow the same pattern. Sensors collect information, such as distance, light, colour or touch. A small computer, the controller, runs a program that decides what to do with that information. Motors, lights or speakers then carry out the result.
Explaining robots this way helps pupils see that a floor robot for five-year-olds and a competition machine for teenagers work on the same principle. The difference lies in how many sensors are used, how complex the program is and how precisely the parts are built.
Free activities to download
Ready-to-run EduTrend Contents introductory robotics workshops for primary, middle and high school. Each free download includes a step-by-step session plan, facilitator notes, three student worksheets and an assessment checklist. Full 20-week programmes are available in EduStore.
Human Robot: Sense, Think, Act
Primary · Ages 7–10
Foundation · 45 min
Pupils take the roles of sensor, controller and motor to act out a robot avoiding obstacles, discovering the sense–think–act pattern all robots share.
Robot Shapes
Primary · Ages 8–11
Developing · 50 min
Pupils program a floor robot or on-screen turtle to trace a square, discover the loop inside it, then work out the turn angles for triangles and hexagons.
Which Sensor for the Job?
Middle School · Ages 11–14
Intermediate · 60 min
Students test light, distance and touch sensors, record readings, and choose the right sensor for tasks such as avoiding walls or following a line.
Why Did It Stop Short?
Middle School · Ages 12–14
Intermediate · 60 min
Students discover why a robot stops short of its target, calculate distance per wheel rotation and calibrate their program to hit a target accurately.
Line Follower Logic
High School · Ages 15–18
Advanced · 90 min
Students program a line-following robot, first with simple on–off control, then with proportional control, and compare smoothness, speed and reliability with data.
