Understanding Robotics: Sensors, Actuators, and Control Systems

Robotics: Sensors, Controllers, and Actuators

A temperature controller-sensor measures the environment’s temperature. Based on this information, the driver activates or deactivates the actuator, which in this case is a radiator.

Sensor input → Driver → Actuator output

A control system is a group of elements that automates a process:

  • Entry: Gathers information.
  • Output: Responds to this information.

Types of Control Systems

Open Loop

Activated regardless of the output.

Wide Area Networks: Characteristics, Technologies, and Protocols

Wide Area Networks

5: Wide Area Networks. Characteristics:

  • Circuit Switching (CC): Involves the existence of a path between two stations, which is a sequence of links connected between the network nodes (switches) to allow information transfer.
  • Packet Switching (CP): The information is chopped into small blocks of information.

Different Technologies: CC and CP. They differ in that switch nodes link the information between communication points.
