150-Centimeter Carbon Fiber Arm for Industrial Robots Designed in Iran

“This arm was designed by using lightweight and durable carbon fiber materials to move parts between two presses in production lines, and its prototype has now been successfully tested and evaluated for performance,” said Alireza Karimi, the director of the Manufacturing and Production Technologies Center at Sharif University of Technology’s Academic Center for Education, Culture and Research.

He explained that previously, due to the long length of metal arms available in the market, moving parts required the entire robot to move, which increased depreciation, energy consumption, and maintenance costs.

“However, with this new design, the arm has a more precise function without the need to move the robot body, which has resulted in a significant reduction in friction and significant cost savings,” Karimi said.

In a relevant development in March, a knowledge-based company, stationed at the incubator center of the Islamic Azad University’s Birjand branch, had also designed and manufactured a robotic arm with applications in different industries.

“The main application of this product is generally in the packaging industry. The main task of the Delta robotic arm is to move objects or pick and place operations; for instance, this device can pick up a bottle of juice on the production line and place it in a box. Another important activity is sorting operations. With the help of machine vision and machine learning, this device is able to grade products or identify and remove defective products on the production line. A camera is also connected to the robot, which automatically identifies and processes the parts,” said Hamed Pamorqi, the managing director of Hamoun San’at Pishro Pasargad company.

He added that the robot also enjoys the capability to move in three dimensions and in its workspace, in addition to packaging and separation, it can also perform a unique operation by placing a tool in its final channel and use it as a machine tool.

“The main advantage of this robotic arm is its high speed, which reaches up to three meters per second and is similar to foreign models. Another advantage of these robots is the way they are placed in the production line, which takes up little space,” Pamorqi said.

“The Delta robotic arm system can perform a number of activities in laboratory environments and spaces where toxic gases exist. In general, this product has a great impact on increasing the quality, speed and efficiency of the production line,” he added.
