To reduces the human efforts and in industries to increase efficiency, proficiency and the most important is to reduce the time. Nowadays a new technology of Robotics is used which can do a specific task. Robotics which is used in most of the developed countries like Germany , France , and Japan, USA, CHINA etc. These Robots are controlled with the remote.
The Robot is programmed for the specific task. Every task of the robot is defined; stoppage timing of the robot and angle of rotation between the two places is defined by the servo motors. This is very wonderful project to control the working of the robotic arm without wire.
The project is to control a robotic arm using the remote control. The remote control works on the RC5 PROTOCOL. It transmits 14 data at a time. The command data is a Manchester coded bit stream modulating a 36 kHz carrier.
The IR signal from the transmitter is detected by a specialized IC (IR receiver) with an integral photo-diode, and is amplified, filtered, and demodulated. The 14 bit contains 2 start bit, 1 toggle bit, 5 address bit and 6 command bit. By receiving the data the coding is done for the operation of the servo motors. As for the particular bit pattern the particular number or motors are to be operated for a particular angle. In this way the robotic arm is controlled using the remote control.
Importance of the Research
To reduces the human efforts, and in industries to increase efficiency, proficiency and the most important is to reduce the time. Through this a person who has no hand can also work by using the robotic arm as a temporary hand.
Contribution of the Project
The project concludes the VLSI implementation of the Remote Controlled Robotic Arm. In this hardware is designed for servo motor by which the motion of the robotic arm can be controlled. Although these do not fall under the category of mobile robotics, the field of robotics essentially started with arms and end-effectors (devices that attach to the end of an arm such as grippers, electromagnets etc).
Arms and grippers are the best way for a robot to interact with the environment it is exploring. Simple robot arms can have just one motion, while more complex arms can have a dozen or more unique degrees of freedom
Servo motors are types of actuators that rotate to a specific angular position, and were classically used in more expensive remote controlled vehicles for steering or controlling flight surfaces.
Now that they are used in a variety of applications, the price of hobby servos has gone down significantly, and the variety (different sizes, technologies, and strength) has increased A hobby servo motor actually includes a DC motor, gearing, electronics and a rotary potentiometer (which, in essence, measures the angle). The electronics and potentiometer work in unison to activate the motor and stop the output shaft at a specified angle.
These servos are generally have three wires: ground, voltage in, and a control pulse. The control pulse is usually generated with a servo motor controller. A "robot servo" is a new type of servo that offers both continuous rotation and position feedback. All servos can rotate CW and CCW
