5. Flexibility and Scalability
Modern robotic systems offer significant flexibility, enabling manufacturers to quickly adapt to changes in product design or production processes. Robots can be reprogrammed or reconfigured to handle different tasks, which makes it easier for companies to diversify their product lines or respond to changing customer demands.
For instance, collaborative robots (cobots) can be integrated into existing production lines with minimal disruption. These robots can work alongside human operators and handle tasks such as material handling, assembly, or quality inspection, all while adapting to different tasks without requiring a complete overhaul of the system.
Types of Robotics Systems in Automated Manufacturing
1. Industrial Robots
Industrial robots are the backbone of automation in manufacturing. These robots are designed to perform a wide range of tasks such as welding, assembly, painting, packaging, and material handling. They typically consist of a robotic arm with multiple joints, which can move in a variety of directions and execute complex movements with high precision.
There are various types of industrial robots, including:
- Articulated Robots: These robots feature multiple joints and can move in a range of axes, providing high flexibility for complex tasks.
