For as long as we can remember, we've wanted our own robot army.
Now, with Mod Robotics' MOSS system, we can assemble our own legion of brightly-coloured, blocky Terminators.
Move over, Lego
The bricks themselves are little cubes in 1x1 or 2x1 configurations, with indentations in the corner to accommodate magnetic balls that hold them together.
They're colour-coded according to function; green bricks are the power source, red bricks contain sensors, black bricks are motors and blue bricks are pass-through connectors. Although the bright plastic bricks seem very kid-friendly, the magnets could easily be swallowed by a small child – so this is definitely a plaything for older children.
Once you've joined a power source, a sensor and a motor together, you've built your first robot. Ours was a feeble effort – a hinge that's manipulated with a rotary knob – but you quickly graduate to more advanced constructions with light sensors, rotors and wheels.
There's even a Bluetooth module that lets you control your creation with an iOS or Android app – Mod Robotics were demonstrating a remote-controlled car, but you can set the app up to direct pretty much anything your fevered imagination can conjure up.
