Scientists of University of Birjand have designed and created Delta Robot for the first time in East part of the country.

According to an ISCA report, the project of Delta Robot has been carried out by Reza Payan, MS student of electrical engineering in cooperation with Reza Zare, faculty member of University of Birjand and Seyed Hossein Mousavi, educational expert in this university.

Based on the report, a delta robot is a type of parallel robot that consists of three arms connected to universal joints at the base. It moves at high speeds and perform repetitive tasks quickly and consistently. They have advantages for many applications in the fields of robotics, such as rigidity, speed, low mobile mass and superior accuracy.

Delta robots are mainly used in applications where the robot is picking products in groups and placing them in a container or in an assembly pattern. They are being used to not only improve consistency and quality of processes where repetitive movements ultimately lead to employee mental fatigue, but they also remove the issue of repetitive motion injuries.

The parallelogram formation guarantees parallelism between the fixed base and a moving platform, enforcing the necessary mechanical constraints to confine the motion within a certain three-dimensional (3D) space. The end-effector is secured to the moving platform and connected to a fourth actuator secured on the mobile platform.

The main benefit of delta robots is that the heavy motors are fixed on the frame, allowing the moving parts of the robot to be very light. In contrast, each motor of an articulated arm robot carries the weight of all the successive motors.
