1. Key components of Robots:
1.1. Power Supply:
A power supply is an electrical device that supplies electric power to an electrical load. It is like food for us, it supplies the controller and actuators with the needed energy to perform a task.
All power supplies have a power input connection, which receives energy in the form of electric current from a source,
and one or more power output connections that deliver current to the load.
The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power converters, or another power supply.
The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.
1.2. Actuators:
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system. It is like muscle for us. In simple terms, it is a “mover”.
An actuator requires a control signal and a source of energy.
The actuator produces only two types of motion (Linear\Translational Motion or Rotary\Rotational Motion), where the motion is differed according to the degree of freedom and kinematic chain of the mechanism.
Its main energy source may be an electric current, hydraulic pressure, or pneumatic pressure. When it receives a control signal, an actuator responds by converting the source’s energy into mechanical motion. In the electric, hydraulic, and pneumatic sense, it is a form of automation or automatic control.
An actuator is a mechanism by which a control system acts to perform an operation or task. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
1.3. Sensors:
A sensor is a device that detects the change in the environment and responds to some output on the other system. A sensor converts a physical phenomenon into a measurable analog voltage (or sometimes a digital signal) converted into a human-readable display or transmitted for reading or further processing.
The most frequently used different types of sensors are classified based on the quantities such as Electric current or Potential or Magnetic or Radio sensors, Humidity sensor, Fluid velocity or Flow sensors, Pressure sensors, Thermal or Heat or Temperature sensors, Proximity sensors, Optical sensors, Position sensors, Chemical sensor, Environment sensor, Magnetic switch sensor, etc.
