Based on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.

How we estimate times · sources and method

Joints and connections across four sub-builds make checking orientation important before assembling the final robot. The three central durations are model-specific editorial assessments. Planning ranges extend approximately from 65% to 145%, rounded to quarter-hours; they are not measured experience-level averages or guaranteed limits.

Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.

The model, the history, the ideas

Inside the set

Four models become one robot

Separating the mech produces four independent builds: a dragon, jet, car and Zane action figure.

Beyond the set

The stories, places and inventions behind your build.

Two arms in space

Dextre is a two-armed robot installed on the International Space Station in 2008. It can work with Canadarm2 to perform maintenance outside the station.

Canadian Space Agency

Commands can come from Earth

Ground teams at the Canadian Space Agency and NASA control Dextre. Space robotics can therefore carry out external work without requiring an astronaut spacewalk every time.
