Educational toy made in plastic versions. In the mid-1950s, more explicitly engineering-themed construction toys appeared, including plastic girders, columns, and panels that could be assembled into a model curtain wall skyscraper. Later, this Girder and Panel structural system was extended to a Hydro-Dynamic setup by adding pipes, valves, tanks, nozzles, and pumps to allow construction of model plumbing, HVAC, and chemical engineering systems like a simulated distillation column. Other extensions of the system supported suburban-style housing developments (Build-A-Home), or monorail transportation systems (Skyrail). The building toy Lego was originally developed by Ole Kirk Christiansen in Billund, Denmark, in the 1930s. The name

Lego Mindstorms' programming is command box programming, rather than code programming. Lego-supplied languages: Popular third-party languages: The Lego camera on its own is technically not a robotic toy; rather, it is a normal webcam (a Logitech QuickCam Web) packaged into a Lego shell. Being a normal webcam, the Lego camera is, unlike most Mindstorms products, not programmable and is only usable connected to a PC or some other device that supports USB webcams.
