What is the working principle of the mechanical block of a robot?

The working principle of the mechanical block of a robot is based on the following aspects:

• Rigid body structure: The rigid body structure of the robot provides the framework and support for its components and determines its overall shape and stability.
• Linkages and joints: The mechanical block of a robot consists of a series of interconnected links and joints, which are able to move independently. Joints allow links to rotate and move.
• Actuators: Actuators are used to trigger joints and links. Commonly used actuators are motors, which provide force to links and joints to move or rotate.
• Controller: The block is controlled by a controller. The task of a controller is to receive sensory information and generate control signals for actuators and other components.
• End-effectors: The mechanical block consists of various end-effectors and manipulators, such as grippers, suction cups, tools for cutting, or specialised tools that help a robot to perform a particular task.
