WHAT IS HUMANOID ROBOT
A humanoid robot is basically a robot shaped like a human.
Humanoid robot is an autonomous robot, because it can adapt to changes in its environment or itself and continue to reach its goal
The difference between Humanoid and other kinds of robot is
Self maintenance
Autonomous learning
Avoid harmful situations to people
property, itself.
Safe interacting with human beings
and environment.
Components of HUMANOID ROBOT
Structure
Power source
Actuation
Sensing
Vision
Manipulation
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.
Power Supply
Pneumatic (compressed gases)
Hydraulics (compressed liquids)
Flywheel energy storage
Organic garbage (through anaerobic
digestion
Nuclear fission is proven (although there are not many robots using it as a power source apart from the Chinese rover tests)
Radio active source
ACTUATION
Actuators are the "muscles" of a robot, the parts which convert stored energy into movement.
The most popular actuators are electric motors and linear actuators.
VISION
Vision refers to processing data from any modality which uses the electromagnetic spectrum to produce an image.
In humanoid robots it is used to recognize objects and determine their properties.
. Most humanoid robots use CCD cameras as vision sensors
MANIPULATION
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
DISADVANTAGES
Robotics and Artificial Intelligence rely one
in same poses many potential hazards.
Due to superior strength, speed and lack of morals
inherent with . They are self-replicate which makes
them nearly impossible to stop..
They have made all the works right from small clerical works to space works easier, which resulted in lack of employment.
They require a power source (batteries, solar panels, wall outlet, etc).
CONCLUSION
Each new innovation brings new hopes and possibilities but also potential dangers and risks are possible
This technology is a boon if we are always awake
confidently controlling the robots from over
coming us.
