Articulated robot

Definition

An articulated robot is a type of robotic arm that consists of joints and links, allowing it to perform a wide range of motions similar to a human arm. This flexibility makes articulated robots highly suitable for various tasks in automation, such as assembly, welding, and painting. Their design typically features multiple rotational joints, which enable them to achieve complex movements and orientations in three-dimensional space.

Review Questions

• How does the design of an articulated robot influence its applications in different industries?
  • The design of an articulated robot, characterized by its multiple joints and flexible range of motion, allows it to perform a variety of tasks across different industries. For instance, in automotive manufacturing, these robots can easily manipulate parts and tools due to their high degrees of freedom. This versatility means they can adapt to various assembly processes, painting applications, and even handling delicate components in electronics manufacturing.
• Discuss the significance of degrees of freedom in the functionality of articulated robots.
  • Degrees of freedom (DOF) are crucial for articulated robots as they determine the range and complexity of movement the robot can achieve. Each joint adds one or more DOF, enabling the robot to position itself accurately in three-dimensional space. Higher DOF allows for more intricate tasks such as reaching around obstacles or working in confined spaces, making these robots more efficient and versatile in their applications.
• Evaluate the impact of sensor integration on the performance and capabilities of articulated robots.
  • Sensor integration significantly enhances the performance and capabilities of articulated robots by providing real-time feedback about their environment. With sensors like cameras and force/torque sensors, these robots can adapt their actions based on external conditions, improving their accuracy and safety during operations. This capability not only allows for more complex interactions but also enables them to work alongside humans in collaborative environments, increasing productivity and efficiency in various tasks.
