These technologies are used to develop machines that can substitute portable caterpillar b30 humans and replicate human actions.
The concept of creating machines that can operate autonomously dates back to classical times, but research into the functionality and potential uses of robots did not grow substantially until the 20th century. Robotics is a branch of engineering that involves the conception, design, manufacture, and operation of robots. This field overlaps with electronics, computer science, artificial intelligence, mechatronics, nanotechnology and bioengineering. The word robotics was derived from the word robot, which was introduced to the public by Czech writer Karel Čapek in his play R. According to the Oxford English Dictionary, the word robotics was first used in print by Isaac Asimov, in his science fiction short story “Liar! In 1948, Norbert Wiener formulated the principles of cybernetics, the basis of practical robotics. Fully autonomous only appeared in the second half of the 20th century.
The first digitally operated and programmable robot, the Unimate, was installed in 1961 to lift hot pieces of metal from a die casting machine and stack them. The latter allegedly presented the king with a life-size, human-shaped figure of his mechanical handiwork. Nikola Tesla demonstrates first radio-controlled vessel. First fictional automatons called “robots” appear in the play R. First full-scale humanoid intelligent robot, and first android. Its limb control system allowed it to walk with the lower limbs, and to grip and transport objects with hands, using tactile sensors. The world’s first microcomputer controlled electric industrial robot, IRB 6 from ASEA, was delivered to a small mechanical engineering company in southern Sweden.

The design of this robot had been patented already 1972. First object-level robot programming language, allowing robots to handle variations in object position, shape, and sensor noise. Robots all have some kind of mechanical construction, a frame, form or shape designed to achieve a particular task. For example, a robot designed to travel across heavy dirt or mud, might use caterpillar tracks. The mechanical aspect is mostly the creator’s solution to completing the assigned task and dealing with the physics of the environment around it. Robots have electrical components which power and control the machinery.
For example, the robot with caterpillar tracks would need some kind of power to move the tracker treads. That power comes in the form of electricity, which will have to travel through a wire and originate from a battery, a basic electrical circuit. All robots contain some level of computer programming code. A program is how a robot decides when or how to do something. In the caterpillar track example, a robot that needs to move across a muddy road may have the correct mechanical construction and receive the correct amount of power from its battery, but would not go anywhere without a program telling it to move. As more and more robots are designed for specific tasks this method of classification becomes more relevant. For example, many robots are designed for assembly work, which may not be readily adaptable for other applications.
They are termed as “assembly robots”. For seam welding, some suppliers provide complete welding systems with the robot i. Caterpillar plans to develop remote controlled machines and expects to develop fully autonomous heavy robots by 2021. Some cranes already are remote controlled. It was demonstrated that a robot can perform a herding task. In the auto industry, they can amount for more than half of the “labor”.
Other hospital tasks performed by robots are receptionists, guides and porters helpers. Robots can serve as waiters and cooks, also at home. This has developed from a hobby in the 1990s to several TV series worldwide. Cleanup of contaminated areas, such as toxic waste or nuclear facilities. Many different types of batteries can be used as a power source for robots. Actuators are the “muscles” of a robot, the parts which convert stored energy into movement.
By far the most popular actuators are electric motors that rotate a wheel or gear, and linear actuators that control industrial robots in factories. There are some recent advances in alternative types of actuators, powered by electricity, chemicals, or compressed air. The vast majority of robots use electric motors, often brushed and brushless DC motors in portable robots or AC motors in industrial robots and CNC machines. These motors are often preferred in systems with lighter loads, and where the predominant form of motion is rotational. Various types of linear actuators move in and out instead of by spinning, and often have quicker direction changes, particularly when very large forces are needed such as with industrial robotics. The resultant lower reflected inertia can improve safety when a robot is interacting with humans or during collisions.
They are used in some robot applications. They have been used for some small robot applications. Recent alternatives to DC motors are piezo motors or ultrasonic motors. These work on a fundamentally different principle, whereby tiny piezoceramic elements, vibrating many thousands of times per second, cause linear or rotary motion. Elastic nanotubes are a promising artificial muscle technology in early-stage experimental development.
