The purpose of this series is to create advanced models of working vehicles and machines, compared to the simpler brick-building properties of normal Lego.

The most significant change from normal Lego is that single-stud wide bricks ('beams') have circular holes through their vertical face.

Tension (resulting from the correct number of chain-link parts used), along with the combination of gearwheel-sizes used, is critical to reliable operation.

Initially liftarms were used primarily as styling parts, or to create smaller sub-assemblies which attached to a studded chassis.

This is due to the amount of flex in the clip-based pins which are used to attach studdless parts together, whereas studs provide a more rigid friction fit.

As of 2005, Lego has begun to re-incorporate studded bricks back into the Technic line, which can be seen in sets such as 8421 Mobile Crane.

It comprised a set of motors, two IR receivers, remote control and a battery box, thus resulting in a remote-control model.
