机器人是机械或虚拟人工剂，通常是由计算机程序使用的机电机器使用electronic circuitry。Robots can be autonomous or semi-autonomous and range from humanoids such as Honda’s is the advanced Step in Innovative Mobility and TOSY’s. TOSY Ping Pong Playing Robot to industrial robots, patent assist robots, medical operating robots, dog therapy robots, collectively programmed swarm robots, and even microscopic nanorobots. By representing a life like an appearance or automating movements, a robot may transfer a sense of intelligence or through on its own. This article discusses IR sensor-based wireless robotic vehicles.
这机器人是一种技术that deals with the design, construction, operation, and application of robots, as well as computer systems, is used to control, sensory feedback, and information processing are called robots. This technology deals with automated machines that can be placed by humans in dangerous environments, or resemble humans in appearance, behavior. Nowadays robots are inspired by nature contributing to the field of bio-inspired robotics. These robots also created a new branch of robotics and soft robotics. The mechanical techniques developed through the Industrial age, there are more practical applications such as automated machines, remote-control, and wireless remote control.
一个IR传感器是一种发出的装置，以便感知周围的某些方面，这些方面检测到IR辐射落在它上。发射器只是IR LED（发光二极管) and the detector is simply an IR photodiode that is sensitive to IR light of the same wavelength is emitted by the IR LED. When IR light falls on the photodiode, the resistances and output voltages, change in proportion to the magnitude of the IR light received. There are many types of IR sensors that are built and can be built depending upon the application. Contrast sensors (Used in线路之后的机器人), Proximity sensors (Used in Touch Screen phones), and obstruction sensors (Used for counting goods and in Burglar Alarms) are some examples.
这RF transmitter circuit diagram is shown below is used to connect different push buttons to move the robotic vehicle in different directions like forward, backward, right and left. Thus, by pressing the appropriate push button, we can control the robotic vehicle’s movement.
RF receiver is also being small in size and RF receiver has supply current of 3.5mA with an operating voltage of 5V. RF transmitter modules are designed to work with 433MHz only (that should match with the transmitter frequency for communication purposes to receive signals from the transmitter).
RF Communication by using the Robotic Vehicle
Radiofrequency (RF) consists of a transmitter and a receiver, which is connected to an isolated circuit that is to be controlled. A control signal is transferred from the transmitter end in the form of radio waves or electromagnetic waves, such that to control the device remotely, which is connected to the receiver end. This control signal is transmitted by using electromagnetic waves or radio waves of radiofrequency. Thus, the control signal received at the receiver end and get the accurate output such as a robotic vehicle, special purpose robot, communication purpose device, and so on.
At the transmitting (TX) section, pushbuttons are used to send the commands to the receiver end to control the robot’s movement, either to move in four directions like forward, right, backward and left, etc. At the receiving section, two motors interfaced with the 8051 family microcontroller where they are used for the vehicle’s movement.
电视远程生成基于RC5的数据，该数据由与微控制器接口接收的红外接收器接收。微控制器中的内置程序是指基于I / P数据产生优选输出的代码，通过电动机驱动器IC运行电机。
Further, this project can be enhanced usingDTMF技术。我们可以使用射频技术control the robot by using a cell phone. This technology has an advantage over long communication range as compared to RF technology.
