What Are Parallel Robots?
Parallel robots, also known as parallel manipulators, represent a unique class within advanced robotics. These machines feature multiple kinematic branches that connect a moving platform to a fixed base, forming a closed-loop structure. Unlike serial robots, which use a single chain of joints, parallel robots rely on several independent chains. This design gives them superior rigidity and precision, making them valuable in custom manufacturing and production environments.
Key Features
Parallel robots stand out in robotics due to their specialized components and mechanisms. Their structure includes:
Actuators (Linear and Rotary): These parts drive movement, allowing the robot to perform tasks with speed and accuracy.
Linkages and Degrees of Freedom (DOF): Multiple rigid links and joints provide the ability to move in three-dimensional space.
End Effector: The platform that interacts with products, ensuring precise handling.
Kinematics: Both inverse and forward kinematics play a role in controlling the robot’s motion.
Parallel manipulators use several arms connected to a single platform, which increases rigidity and improves motion control. This configuration supports high productivity and consistent quality in industrial robots.
Parallel robots excel in tasks requiring extreme precision, ideal for electronics manufacturing.
