Mini Robots

Mini Robots (40413) is a small LEGO® Mindstorms set with 366 pieces built around compact robot figures rather than one large model. Its 145 unique parts lean heavily on technic-style connectors and joints, and there are no minifigures, since the built robots are the focus.

Description

Several builds, not one big model

Instead of one large finished model, the 366 pieces here are meant to be built into several small, independent robot figures. That structure suits builders who like trying out different design ideas within a single box, such as different leg or arm mechanisms, more than a single long build. Anyone who enjoys starting fresh a few times over rather than finishing one long project will get more variety out of this set than out of a typical single-model box. Once the first robot is taken apart, the same pieces go straight into a second or third design.

145 technic-style parts

The 145 unique elements lean towards connectors, axles and joint pieces rather than plain bricks, giving far more articulation than a standard set of similar size. Those parts are what allow the small robots to have moving arms and legs. Builders already familiar with LEGO Technic or Mindstorms will recognise many of the shapes, even though this particular set has no motors or electronics of its own. That part variety also makes it a useful top-up for an existing Technic collection.

A restrained colour scheme

Black, white, light bluish grey and dark turquoise make up the palette, giving the robots a clean, technical look rather than a bright toy aesthetic. The parts list on this page breaks down exactly which of the 145 parts come in which colour and quantity, which is useful both for rebuilding a specific model and for sourcing extra pieces in a particular shade.

Who this set suits

With no motors, sensors or minifigures, Mini Robots is built for anyone who enjoys the construction side of Mindstorms without needing to programme anything. At 366 pieces the focus stays entirely on the robot figures themselves rather than on any surrounding scene. It also works as a lead-in to Technic-style building before moving on to larger, motorised models, once motors and sensors from a full core set are added.
