Structure
The structure of a robot is usually mostly mechanical and can be called a kinematic chain.
The chain is formed of links (its bones), actuators (its muscles), and joints which can allow one or more degrees of freedom.
Types of joints
Respectively, a ball joint, which allows rotation around x, y, and z, a hinge joint, which allows rotation around z, and a slider joint, which allows translation along x.
Effectors
Component to accomplish some desired physical function
Examples:
Hands
Wheels
Gripper
A welding torch
A paint spray gun
Actuators
Actuators are the "muscles" of a robot, the parts which convert stored energy into movement.
The most popular actuators are Servomotors, Stepper motors,
Pneumatic cylinders, hydraulic cylinders.
Manipulators
Robots which must work in the real world require some way to manipulate objects; pick up, modify, destroy, or otherwise have an effect.
Thus the 'hands' of a robot are often referred to as end effectors, while the arm is referred to as a manipulator.
Some manipulators are:
Mechanical Grippers
Vacuum Grippers
General purpose effectors
Power Supply
Suitable power supply is needed to run the motors and associated circuitry.
Typical power requirement ranges from 3V to 24V DC
220V AC supply must be modified to suit the needs of our machine
Batteries can also be used to run robots
Robots are driven by different motors :-
DC Motors
Stepper Motors
Servo Motors
