Mindstorm Lego brick manufacture. Technician assembling Mindstorm programmable Lego bricks. Each unit will contain a computer which can interact with its environment allowing its use to build robots. The Mindstorm has the traditional Lego protrusions on its surface so conventional Lego bricks may be built on it. Each Mindstorm has an LCD display, light and touch sensors (not seen) and an output port (black) for electric motors. Mindstorm bricks can be used to create autonomous toys with behavioural traits. Such traits would be the ability to follow a trail, move around objects and seek out light or dark areas. Photographed in Baar, Switzerland.
