Mechanism collection of TU Delft, Netherlands Images, films, descriptions                                                               

“White Board” models (1 – 35): The white board and the coloured parts are made of plastic (perspex).

Models 36 - 61 are made of metal (mainly aluminium alloy).

The 3D-video animations (models 11, 13, 36 and 40) are created with 3D-CAD software
