Locomotion Device
Human beings use muscles to give movements to their arms,
palms and fingers. For a robot, the power comes from motors.
Three fuels are used in locomotion, depending on the energy
source. There are three widespread types of Locomotive devices
namely Electric, Hydraulic and Pneumatic.
Controller
Human beings and animals sense their surroundings through
their sense organs and then react accordingly based on the
sense organs’ feedback. Robots use the same response system
as human beings-the feedback system. The CPU of a robot does
the same thing based on data collected by its sensors. There are
mainly two types of controllers that determine the robot’s behaviour. They are Simple Controller
and Strong Sensory Controller.
Sensors
Without the data supplied by the sense organs, the
human brain cannot perform intelligently in any
given situation. Similarly, controllers would be unable
to perform if the robot’s sensors do not constantly
feed the controller about their position, force,
temperature, etc. The sensors are the powerhouse of
a robot’s feedback system and act as eyes and ears.
A wide range of sensors is used in a robot system to perform the tasks.
Power Supply
Just like human beings consume food when they need energy, robots need energy too to
function. Electricity is the primary source of energy for most robots. Stationary robots used in
the factories use direct power. Mobile robots use high-capacity batteries. Robotic spacecrafts
and satellites are generally equipped with solar panels.
