Have a look at the video above for an amazing example of what a commercial delta robot can do. Asurofilmchen has decided to build a DIY version of one of these. Obviously it won’t have the same speed or dexterity but it is still a challenging undertaking! My favorite delta robot example is still the Croissant Picker Robot though.

"A Delta robot is a type of parallel robot. It consists of three arms connected to universal joints at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector. The Delta robot (a parallel arm robot) was invented in the early 1980s by Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland). The purpose of this new type of robot was to manipulate light and small objects at a very high speed, an industrial need at that time. In 1987, the company Demaurex purchased a license for the Delta robot and started the production of Delta robots for the packaging industry. In 1991 Reymond Clavel presents his doctoral thesis ‘Conception d’un robot parallèle rapide à 4 degrés de liberté’ and receives the golden robot award in 1999 for his work and development of the Delta robot. Also in 1999, ABB Flexible Automation starts selling its Delta robot, the FlexPicker. By the end of 1999 the Delta robots are also sold by Sigpack Systems."
