History Of Robots
Hello friends there sachin a mechanical engineer and presenting a brife history of robots development which helps you definitely to improve your knowledge and strong your robots projects technically

1818 - Mary Shelley wrote "Frankenstein" which was about a frightening artificial lifeform reated by Dr. Frankenstein.
1921 - The term "robot" was first used in a play called "R.U.R." or "Rossum's Universal Robots" by the Czech writer Karel Capek. The plot was simple: man makes robot then robot kills man!
1941 - Science fiction writer Isaac Asimov first used the word"robotics" to describe the
technology of robots and predicted the rise of a powerful robot industry.
1942 - Asimov wrote "Runaround", a story about robots which contained the "Three Laws of Robotics":

A robot may not injure a human, or,through inaction, allow a human being to come to harm.
A robot must obey the orders it by human beings except where such orders would conflicts with the First Law.
A robot must protect its own existence as long as such protection do not conflict withe the First or Second Law.
1948 - "Cybernetics", an influence on artificial intelligence research was published by Norbert Wiener.
1956 - George Devol and Joseph Engelberger formed the world's first robot company.
1959 - Computer-assisted manufacturingg was demonstrated at the Servomechanisms Lab at MIT.
1961 - The first industrial robot was online in a General Motors automobile factory in New Jersey. It was called UNIMATE.
1963 - The first artificial robotic arm to be controlled by a computer was designed. The Rancho Arm was designed as a tool for the handicapped and it's six joints gave it the flexibility of a human arm.
1965 - DENDRAL was the first expert system or program designed to execute the accumulated knowledge of subject experts.
1968 - The octopus-like Tentacle Arm was developed by Marvin Minsky.
1969 - The Stanford Arm was the first electrically powered, computer-controlled robot arm.
1970 - Shakey was introduced as the first mobile robot controlled by artificial intellence. It was produced by SRI International.
1974 - A robotic arm (the Silver Arm) that performed small-parts assembly using feedback from touch and pressure sensors was designed.
1979 - The Standford Cart crossed a chair-filled room without human assistance. The cart had a tv camera mounted on a rail which took pictures from multiple angles and relayed them to a computer. The computer analyzed the distance between the cart and the obstacles.

    To Improve the control algorithms of a robots
    The study of motion can be divided into Dynamics & Kinematics. Dynamics are used to study the effect of forces upon these movements. Direct dynamics refers to the calculation of accelerations in the robot once the applied forces are known. Direct dynamics is used in computer simulations of the robot. Inverse dynamics refers to the calculation of the actuator forces necessary to create a prescribed end effector acceleration.Direct kinematics refers to the calculation of end effector position, orientation, velocity and acceleration when the corresponding joint values are known. Inverse kinematics refers to the opposite case in which required joint values are calculated for given end effector values, as done in path planning. Some special aspects of kinematics include handling of redundancy collision avoidance and singularity avoidance. Once all relevant positions, velocities and accelerations have been calculated using Kinematics

    • Identification,Modelling and Control of a (Mobile) Hydraulic Arm.
    Some problems to be solved:
    • Create a complete Kinematic model for the hydarulic Arm.
    • Create a dynamic model for the arm, and identify the relevant parameter values.
    • Interface to the hydraulics there is currently a radio link to the hydraulic actuators. You'll be able to use to that. However this will require programming and finding and buying the needed interface hardware.
    • Model/identify the hydraulic components.
    • Design a good "dead reckoning" model for the system. (I.e. predicting the state from the control inputs.)
    • Design/test control laws. Optronic sensing for estimating the state of the system (in conjunction with your dead reckoning model) will be provided.

    What is robotics
    Robotics is the science and technology of robot, their design, manufacture, and application.

    The field of computer science and engineering concerned with creating robots, device that can move and react to sensory input. It is also a branch of artificial intelligence.

    The term robotics was introduced by writer Isaac Asimov. In his science fiction book I Robot, published in 1950, he presented three laws of robotics:
    1. A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
    2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
    3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
