A Robot can be defined as a programmable, self-controlled device consisting of electronic, electrical, or mechanical units. More generally, it is a machine that functions in place of a living agent. Robots are especially desirable for certain work functions because, unlike humans, they never get tired; they can endure physical conditions that are uncomfortable or even dangerous; they can operate in airless conditions; they do not get bored by repetition. The intent of this paper is to successfully engineer and construct an autonomous Mobile Robotic Arm that would exhibit sophisticated machine intelligence behaviors. I chose to build an autonomous PC propelled Mobile Robotic Arm based on interfacing through the parallel port. The interfacing circuit I used, enabled us to implement electronic tasking behaviors, and manipulation of DC motors.

[...] Hidden field will contain the value as per the Figure 10: IR sensor through control The Infrared Transmitter and Receiver are used to stop the movement of the robotic arm when User wants . The IR transmitter sends the signal to the IR receiver whenever I want to stop the movement of the robotic arm by the switching the IR transmitter. The IR receiver takes the signal and then it is having one counter IC which count alternatively 0 and 1 so when IR receiver gets the bit it switch from 0 level to 1 level so that cause the relay on the receiver side to make it on when the signal is received. [...]
[...] user selects car forward operation then value passed in the hidden field is 1 and so depending on the value in hidden field, value passed through the socket connection will be 52; on input of which server will send pattern of bits on output port which will move the car forward IR SENSOR THROUGH CONTROL Figure Network through control The user anywhere in the world can control our robotic arm with the help of HTML, serves and Visual Basic as basic tools for the network communication between the remote user and the application running and controlling robotic arm.

[...] Relay is electro magnetic switch .Here I am using 1-CO Relay which is having 5 pins, in which 1 line is NO (not open) and other line which is NC (not closed) MOTOR Figure Motor The main component of my robotic arm is motor. I am using +6V D.C. motor and Synchronous motor for different movements. For operating motor required voltage is 6V. When I give +6V to motor it rotates in clockwise direction and -6V to motor it rotates in anticlockwise direction NETWORK THROUGH CONTROL movement selected. [...]
