Delta with 4 degrees of freedom: developed by the company Adept, which has 4 parallelogram directly connected to the end-platform instead of having a fourth leg coming in the middle of the end-effector.

This allows for very high speed and high accelerations.
As a result of this, the moving parts of the delta robot have a small inertia. Since the actuators are all located in the base, the arms can be made of a light composite material. Actuation can be done with linear or rotational actuators, with or without reductions ( direct drive). Actuation of the input links will move the triangular platform along the X, Y or Z direction. The ends of these arms are connected to a small triangular platform. From the base, three middle jointed arms extend. The robot's base is mounted above the workspace and all the actuators are located on it.
only movement in the X, Y or Z direction with no rotation. 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. The robot can also be seen as a spatial generalisation of a four-bar linkage. it consists of multiple kinematic chains connecting the base with the end-effector. The delta robot is a parallel robot, i.e. In 2017 Harvard's Microrobotics Lab researcher Hayley McClintock miniaturized it with piezoelectric actuators to 0.43 grams for 15 mm x 15 mm x 20 mm, capable of moving a 1.3g payload around a 7 cubic millimeter workspace with a 5 micrometers precision, reaching 0.45 m/s speeds with 215 m/s² accelerations and repeating patterns at 75 Hz. By the end of 1999 delta robots were also sold by Sigpack Systems. Also in 1999, ABB Flexible Automation started selling its delta robot, the FlexPicker. In 1991 Reymond Clavel presented his doctoral thesis 'Conception d'un robot parallèle rapide à 4 degrés de liberté', and received the golden robot award in 1999 for his work and development of the delta robot.

In 1987, the Swiss company Demaurex purchased a license for the delta robot and started the production of delta robots for the packaging industry.
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. After a visit to a chocolate maker, a team member wanted to develop a robot to place pralines in their packages. The delta robot (a parallel arm robot) was invented in the early 1980s by a research team led by professor Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland).
