Parallel kinematics refers to a type of mechanical system where multiple arms or links connect a platform to a fixed base. This configuration allows for precise movement and positioning of the platform, making it ideal for applications like robotics and CNC machines. The design enhances stability and reduces the effects of inertia, leading to improved performance. In parallel kinematics, the motion of the platform is controlled by the simultaneous movement of the arms. This contrasts with serial kinematics, where joints are connected in a single chain. Systems like the Stewart platform exemplify parallel kinematics, showcasing its advantages in tasks requiring high accuracy and speed.
