Robotic Arm Classification: Kinematic Structure
The kinematic structure of a robotic arm defines the number and types of joints, as well as the way these joints are connected, allowing the arm to move and manipulate objects in space. Below are some common kinematic structures for robotic arms.
Serial Robots
These robots have a series of links and joints that move in a chain, with each joint controlled by a motor or actuator. They are the most common type of robotic arm and are used in a wide range of industrial applications, from welding and painting to pick-and-place and assembly tasks.
Parallel Robots
Parallel robots have multiple chains of links and joints that are connected to a common base or platform. This design allows them to maintain high precision and stiffness while handling heavy loads. They are often used in applications that require high-speed, high-precision movements, such as pick-and-place operations, 3D printing, and machining.
Anthropomorphic Robots
Anthropomorphic robots have a structure that mimics the human arm, with a shoulder, elbow, wrist, and fingers. They are often used in applications that require high dexterity and flexibility, such as surgery, rehabilitation, and assembly.
