Several "linear delta" arrangements have been developed where the motors drive linear actuators rather than rotating an arm. Such linear delta arrangements can have much larger working volumes than rotational delta

The key concept of the delta robot is the use of parallelograms which restrict the movement of the end platform to pure translation, i.e. only movement in the X, Y or Z direction with no rotation.

Industries that take advantage of the high speed of delta robots are the food, pharmaceutical and electronics industry. For its stiffness it is also used for surgery, in particular, the
