1. Sensors
The sensor is the perception system of the service robot, which can monitor the surrounding environment in real time through the information in the perception environment. Sensors include vision, hearing, touch, and environmental sensors, among others, which can provide external information and data to service robots.
Second, the control system
The control system is the brain of the service robot, including electronic components such as computers, microcontrollers, and processors. It is able to analyze the information collected by the sensors through algorithms and control and adjust the robot's behavior through a decision-making system. The control system also includes the robot's self-learning ability, so that the robot can develop and improve itself.
3. Executive Agency
The actuator is the power system of the service robot, including motors, pneumatic devices, hydraulic systems, etc. They are able to translate the instructions given by the control system into specific actions to realize the actions and tasks of the robot. The type and number of actuators vary depending on the task of the service robot.
Fourth, human-computer interaction interface
The human-computer interaction interface is the interface between the service robot and the human user, which can be divided into voice, vision and touch and other ways. They are able to provide a good user experience for people, allowing robots to better understand and meet human needs.
