Robot: An Important Roles Of Robots In The Human Society

Superior Essays
Increasingly nowadays, robots have the potential to interact with people daily, and in the not-so-distant future, they will play an essential role in human society.
Defined as a mix of electronics, mechanics and programming, a robot is supposed to “sense” information from its environment through its sensors, analyse and deal with the sensor data, come to a decision and carry out necessary actions or perform something in response, regardless of the robot is autonomous, or guided by a human.
Most of the robots are semi-autonomous, i.e. some decisions are intelligently controlled by the robot, while others are controlled by a human. For example, the case of Mars Rover, which was able to operate with own intelligence while taking high-level

The common control technique is to supply instructions to a robot so that it responds in a specific way for specific situations. For example, for an autonomous robot that avoids objects, the application tells the robot to back off anytime the robot comes into an object: a specific response to a specific condition. This activity does not need any human guidance, it is pre-programmed and does not give intelligence to a robot.
Fuzzy logic, evolutionary computation, hierarchical control, neural networks, etc. are some of the control techniques used for autonomous robots. Neural networks help a robot learn from its experience and environment and act specifically. Research in artificial intelligence is evolving, but for the time being, the robot does what it is set to do.
Rich knowledge in computer science, mathematics, electrical and mechanical engineering, systems engineering, is required to grasp the complexity of robots and their

Considering the three-layer architecture approach, the lowest level of control is the behavioral control (driver). It directly connects sensors and actuators. While these are typically hand-crafted functions written in C or C++, there have been specialized languages developed for behavioral control, including ALFA, Behavioral Language and REX. It is at this level that traditional control theory resides [1].
The second layer is the executive layer (platform). It represents the interface between the numerical behavioral control and the symbolic planning layers and it is responsible for translating high-level plans into low-level behaviors, invoking behaviors at the appropriate times, monitoring execution, and handling

    Algorithmic models of SI behaviour are called computational swarm intelligence (CSI) [2].The application of swarm principles to robots is called swarm robotics. “Swarm Intelligence” refers to the more general set of algorithms. Swarm robotics is the study of how large number of relatively simple physically embodied agents can be designed such that a desired collective behaviour leads to accomplishment of a complex task. II. OBJECTIVES The research of swarm robotics is to study the design of robots, their physical body and their controlling behaviours.…

    Why we need artifial intelligence in robots? The artificial intelligence make the robot have a specific tasks and goal and its job to do it or to solve it as the artificial intelligence works with this goal as a problem and divided it into sub-problems and then put many assumption until the robot solve this problems and save time and effort to the humans. So artificial intelligence helps the robots to act like a people in thinking, learning, talking and moving and also in making tasks and that mean a robots with brains robots with brains can do many things with no risk for human to be harmed in this job, with better accurate and more time as robots don't sleep. artificial intelligence make the robots do something different and unusual in case of changing in any condition and that mean a difference in the routine of doing a job so ordinary machine can't deal with any change while machine with artificial intelligent could deal with this problem and solve it so robots with artificial intelligence is like a human deal with problems with his brain and this is the difference between the automatic artificial intelligent machine and ordinary one which need an person to work on it and take every…

    In addition, the public needs to keep up with technology to stay productive and relevant in the world. It is very simple for a computer to solve problems but its execution is difficult. Firstly the computer or robot gathers facts about a situation via sensors or human input. The computer will compare the information to store data and decides what the information signifies. Thereafter the computer will decide which action it should take that will turn out to be more successful based on the information gathered.…

    4) Behaviour-based control:- It is a method in robotics that focuses on robots that are able to exhibition complex-appearing behaviour regardless of little internal variable state to model its direct environment. Mostly behaviour based control is also a reactive, which means they need no programming of internal representation of what robot looks like or how they move on.it shows more biological actions then their computing counterparts.it makes mistakes, repeats actions and appears confused. Sometimes it is weak artificial intellect, though it is requested as model of intellect. Fields of…

    The force – sensorless method is also applied to rehabilitation applications. Gravity and friction of robots and human arms were estimated by using the relationship between kinematic information and reaction torque of the actuators [8]. Pneumatic is another actuator that is used in rehabilitation application. The force-sensorless method was also applied to the pneumatic actuators by using the relationship between position and pressure of actuators to estimate gravity of the robots and human arm [9]. Nevertheless, using pneumatic to be the actuators made the system more complicated.…
