Introduction to Robotics
Robots are complex machines made of many different components, each of which serves a specific purpose. These components can be divided into two broad categories: hardware and software. The hardware consists of the physical components that make up the robot, such as the body (chassis), actuators, sensors, and power source. The software is the programming that controls the robot's behavior, allowing it to move, sense its environment, and perform other tasks. In this lesson, we will focus on the hardware components of a robot.
The body or chassis of a robot is its physical structure, which holds all of its other components. The design of the body can vary widely, depending on the robot's intended use. Some robots have a simple, box-like shape, while others have a more complex, humanoid form. The body also provides protection for the robot's sensitive internal components.
Actuators are the components that allow the robot to move. There are many different types of actuators, including motors, servos, and hydraulics. Motors are typically used for simple, linear movements, such as rotating a wheel, while servos are used for more precise, controlled movements, such as lifting an arm. Hydraulics are used for heavy-duty applications, such as moving large objects.
Sensors are the components that allow the robot to sense its environment. There are many different types of sensors, including cameras, microphones, and pressure sensors. Cameras are used to provide visual feedback to the robot, while microphones are used to detect sound. Pressure sensors can be used to detect changes in the robot's environment, such as changes in temperature or pressure.
The power source is the component that provides energy to the robot's other components. There are many different types of power sources, including batteries, fuel cells, and solar panels. The choice of power source depends on the robot's intended use and the requirements of its other components.
