Your dream partner:
- is faithful,
- doesn't complain,
- is always efficient,
- is always in the mood for sex,
- is never tired,
- fulfills all the desires (sexual as well),
- is discreet and will tell nothing to anyone about it?
Slowly these fantasies turn into reality.
Already, there are android robots on sale. The androids any beings whose body structure resembles that of a human. Currently, robots aren't enough natural. Despite increasingly sophisticated, leather-like material, they still lack naturality in their movements. The driving systems are being to improved, so in the near future we can expect a naturally moving android robot. The initial aim of humanoid research was to build better orthosis and prosthesis for human beings. A few examples are: powered leg prosthesis for neuromuscularly impaired, ankle-foot orthosis, biological realistic leg prosthesis and forearm prosthesis.
Currently, robots are able to speak and to recognize its
owner's face. What do the current android robots lack? - Character. Each
of us is different and expects different partner's behaviour. Soon, you
will be able to choose between a dominant brunette and submissive
blonde. The solution to obtain the maximum of human behaviour for robots
will be software. The coupling of sensors, propulsion systems and
software allow for the analysis ambient environment and the appropriate
response. An artificial intelligence (cognitive science, linguistics
combination) will help in the analysis. Engeeniers' task for the robot
is that it will be able to understand human intelligence, reason and act
like humans.
What will the people's reaction to the android robots
be like? People often call their cars or iPods affectionately. The man
attributes human traits to the machines, that are used everyday.
An android robot is an autonomous robot. Androids are built basing on humanoids. They can adapt to changes in its environment or in itself and continue to reach its task. Some of the abilities of a humanoid robot may include:
- self-maintenance (i.e. recharging itself)
- autonomous learning
- avoiding harmful situations to people, property, and itself
- safe interacting with human beings and the environment
Androids lack emotions in speech.
The imitation of natural movements and facial expressions are getting better. Engineers can teach a robot human behavior, movements and reactions. It is possible to simulate emotions in the voice of the robot.
Various humanoid and android robots and their possible applications in daily life are featured in an independent documentary film called Plug & Pray, which was released in 2010.
A sensor is a device that measures some attribute of the world.
Sensing plays an important role in robotic paradigms. Sensors can be
classified according to the physical process with which they work or
according to the type of measureable information that they give as an
output.
Human inner ears are used to maintain balance and
orientation. Android robots use proprioceptive sensors, which sense the
position, the orientation and the speed of the android's body and
joints.
- accelerometers to measure the acceleration (velocity can be calculated by integration)
- tilt sensors to measure inclination
- force sensors placed in robot's hands and feet to measure contact force with the environment
- position sensors, that indicate the actual position of the robot (velocity can be calculated by derivation).
Exteroceptive
sensors (categorized as a proximity sensors) determine the measurements
of objects relative to a robot's frame of reference. They allow the
detection of an object near the robot, and they measure the distance
from the object.
Contact Sensors are used to detect the positive
contact between two mating parts and/or to measure the interaction
forces and torques which appear while the robot manipulator conducts
part mating operations. Another type of contact sensors are tactile
sensors. These measure a multitude of parameters of the touched object
surface.
Vision Sensors: Robot vision is a complex sensing process.
It involves extracting, characterizing and interpreting information from
images in order to identify or describe objects in environment.
Actuators are responsible for motion of the robot.
Android
robots are constructed in such a way that they mimic the human body, so
they use actuators that act like muscles and joints, having different
structure though. To achieve the same effect as human motion, android
robots use mainly rotary actuators, which can be either electric,
pneumatic, hydraulic, piezoelectric or ultrasonic.
Maybe in the future we're going to use Electroactive Polymer Artificial Muscle:
Planning and control
In planning and control, the essential
difference between androids and other kinds of robots (like industrial
ones) is that the movement of the robot has to be human-like (biped
gait). The ideal planning for humanoid movements during walking should
result in minimum energy consumption, like it does in the human body. To
maintain dynamic balance during the walk, a robot needs information
about the contact force and its current and desired motion.
