Our verdict
A robot that follows a line is pure magic to a curious kid — and the fact that they soldered it themselves makes it stick. It is a step more involved than a buzzing bug, so it suits slightly older children, but the payoff in engagement and learning is hard to beat.

Getting started with the MiOYOOW Line-Following Robot Car Kit
Solder the sensor components carefully and at the specified height — sensors that sit too far from the floor read the line poorly, which looks like a circuit fault but is a mechanical one. Test the motors before fitting the wheels, and if the car veers off the line, check sensor spacing and the line width before suspecting your joints. Draw the first track with a thick black marker on white paper.

MiOYOOW Line-Following Robot Car Kit: common questions
How does a line-following robot work?
Infrared sensors underneath look for the contrast between a dark line and a light surface, and the circuit steers the motors to keep the line centred. Building one is a tidy introduction to sensors and motor control.
What age is this kit for?
Around ten and up with supervision, or younger alongside an adult. It is a step up from a buzzing-bug kit in both joint count and assembly.
Why does the car not follow the line?
Usually the surface or the line itself: a thin, faint or glossy line confuses the sensors. Use a wide matte black line on white paper, then check sensor height and motor wiring before reworking joints.
