What Is The Industrial Robot Called?
Key Takeaway
The industrial robot is commonly called a robotic arm or manipulator arm. The most prevalent type is the articulated robot, which resembles a human arm with multiple joints allowing for a wide range of movements. Other types include Cartesian robots, known for their accuracy and simplicity, and SCARA robots, which stand for Selective Compliance Articulated Robot Arm. Polar robots have a long reach and simple control systems, while Delta robots are the fastest but most expensive. These names reflect the specific design and function of each robot type, widely used across industries like manufacturing, logistics, and agriculture.
Articulated Robots: Robotic Arms
Articulated robots, commonly known as robotic arms, are among the most versatile and widely used industrial robots.

Polar and Spherical Robots
Polar and spherical robots, also known as spherical coordinate robots, operate within a spherical coordinate system, offering unique movement capabilities. These robots are characterized by their rotary base and linear arm, which allows them to cover a wide range of motion within a spherical area. This design is particularly beneficial for tasks requiring the ability to reach around objects or navigate confined spaces.
In practical applications, polar robots are commonly used for material handling and welding tasks. Their ability to maneuver around obstacles and into tight spaces makes them ideal for environments where space is limited and precision is crucial. For instance, in material handling, polar robots can efficiently move items from one location to another, navigating complex pathways without the risk of collision. In welding, their flexible reach allows for precise welds in difficult-to-access areas, enhancing the quality and strength of the final product.
Understanding the mechanics of polar and spherical robots is essential for engineers who aim to optimize their use in various industrial scenarios. These robots’ versatility and adaptability enable them to perform tasks that might be challenging for other types of robots. By leveraging the unique capabilities of polar and spherical robots, engineers can improve operational efficiency and tackle complex tasks with greater ease. For newly joined engineers, mastering these robots means being able to deploy them effectively in situations that demand flexible and precise movement, ultimately driving innovation and productivity in industrial processes.
Delta Robots: High-Speed Applications
Delta robots, renowned for their high-speed capabilities, are uniquely designed with a triangular structure. This design is not just for aesthetics but serves a critical functional purpose. Delta robots are ideal for tasks requiring rapid and precise movements, making them perfect for high-speed applications such as packaging, sorting, and assembly. Their lightweight arms and parallel kinematic design significantly reduce inertia, enabling faster acceleration and deceleration compared to other robotic designs.
In industries where speed and accuracy are paramount, such as food processing and pharmaceuticals, delta robots excel. For example, in food processing, these robots can quickly sort and package products with minimal error, ensuring that production lines move swiftly and efficiently. In pharmaceuticals, the precision of delta robots is crucial for tasks like sorting pills or assembling delicate components, where even the slightest mistake can be costly.
The parallel kinematic design of delta robots provides a stable and repeatable motion, which is essential for maintaining high quality and consistency in production. For engineers, mastering the use of delta robots can lead to significant improvements in throughput and efficiency. Understanding the mechanics and capabilities of these robots allows engineers to optimize their deployment, ensuring that they can meet the high demands of fast-paced manufacturing environments.
