Delta(Spider Like Robot)

In 3D printers, there's the Rostock.

In lightweight, high-speed applications, there's ABB's FlexPicker.

For high-accuracy, high-rigidity work, there's the Tricept/Exechon.

aslo Motoman have this type of articulate robot.

That's not a question with a good answer. Delta robots are so specialized there are seldom any normal articulated robot the directly competes with them. The ABB FlexPicket, for example, has a tiny payload capacity (1-2kg, IIRC), but can move that payload at very high speed. On the other hand, it has a very limited envelope and is limited to palletizing-style operations. So it is difficult to make a direct comparison.

The Tricept/Exechon robot is, I believe, quite expensive, but it tries to provide (some of) the envelope and flexibility of an articulated robot with (most of) the rigidity and accuracy of a CNC machine.

Basically, in the market so far, most Delta robots are made for highly specialized applications where there's no direct competition from articulated robots.
