ABOUT ROBOTS
Robots are mashines that can move around on their own and do work on their own. That is, they do not have any driver inside or operator just outside that is stearing their behaviour.
Robots can be manually remote controlled by radio signals, controlled wholly authomaticly or partially authomaticly. There is however allways some degree of manual control. As a minimum the robot must be given an initial command to move around and act and to come back and stop.
If a robot is authomatic, it will contain a computer that is conducting its behaviour or the computer is placed centrally and the robot is lead by remote radio controle.
The authomatics in a robot can be more or less intelligent. As a minimum the authomatics is only a fixed program. But more advanced robots can have a degree of artificial intelligense built in. The degree of intelligence can be of 4 stages.
- In stage 1. the robot only does a sequence of strict preprogramed movements.
- In stage 2. the robot still do a strict sequence of preprogrammed operations, but it senses the surroundings and plan each movement in each operation so that it is done optimally.
- In stage 3 there is a purpose or higher command built in. The robot senses the surroundings and compose the sequence of opertations to fullfill these purposes. During each operation it again senses the surroundings and determine the best movements for each operation.
- In stage 4 the robot analyzes the outcome and echonomy af each operation and learns thereby how to behave most efficiently. This learning will then make its bahaviour steadily more efficient.
Robots have gradually been being developed since the nineteen thirties. Only in the recent years robots have been developed that can do any practical work. Still these robots have a very limited use or can move around and act in a very limited types of terrain or environment.
There have all the time been two main types of problems that still are only partly solved. It has been very difficult to construct robots that can move around in a complicated terrain. Such a robot must have some forms of legs. Wheels do not work in a difficult terrain.
It has however been difficult to construct legs flexible enough to be useful. Secondly it has been difficult to make programs and sensor systems to contole the movements of robotic legs in a flexible way and appropriate way.
The way of making such controle will probably be to have a logical controller for each limb. This controller must get input from the controller of the paired limb, and input from the controller of the limbs at front and behind, and even the controllers of any limb at a greater distance. Then there must be a superior controller that gives directions to each of the controllers of the limbs. These controllers can be separaqte hardware units or program units in a common computer.
This is the way that movements in simple animals are coordinated, for example movements of insects. Anatomically these have a brain that works as the common controller. In each section of their body they have a doubled nerve ganglion that controls the two limbs in that section. They have a nerve string that issues commands and information between the brain and all the ganglions. Probably the brain maily issues commands about direction and speed to the other ganglions, and these then controle and coordinate the movements of the limbs.
The other great problem is to construct complicated legs, arms and working equipment that have enough power. This must be some kind of muscular system, but a powerful muscular system is very difficult to make. An solution may be some kind of electric muscles containing powerful electromagnets that not only can extend or shorten the muscle, but also can hold it rigidly at a definite length when great forces pulls or pushes at the muscle.
Another possibility is to construct muscles based on molecular technology (nano-technology) that mimic the principles of muscles in living organisms, or even use living muscles that have been grown in factories.
Robots that move in a easy terrain and are capable of doing simple, or very specialized work are by now in use.
An example is robots used to disarm mines or other explosive objects. Another example is diving robots used to explore subsea areas and fetch up objects from deep sea.
A third example are robots used during laparoscopic surgery (key-hole surgery). The surgeon sits comfortably at a controle station and conducts the work of the robot with handles.
In factories where goods are mass-produced, most of the assambling, fernisment and painting is by now effected by robots. The movements of the robots are preprogrammed, often by guiding the arms of the robots in a programming session. The robot memorizes the movements and repeat them in daily production.
A drone is a robot that can move through the air over a long distance. They are often constructed as an ordinary airplane or helicopter. They can be operated from a bace, but can also make their own decisions according to their probramming. Drones are by now extensively used by the military for surveillance, for bombing and for destroying targets by guns or missiles.
