WiFi Controlled Robotic Vehicle Electronic Project Abstract

This project is a robot vehicle that can be controlled through any computer wirelessly using a WiFi link. It transmits real-time video to the controlling computer using the same link. The video transmitting camera mounted on it. It also has obstacle detection,temperature,sound and light sensitivity feature.

Usually robots are controlled through a laptop using an WiFi link which is subject to attenuation, noise and has a very limited range as well. This project features a robot that uses WiFi 802.11G standard for its control signals through TCP/IP protocol, which has flow control. This enables uninterrupted and reliable transmission of control signal to the robot vehicle. WiFi support high data rates which enables good quality uninterrupted video transmission from the robot to the computer. Image capturing is done by mounting an IP-camera over the Robotic Car. Obstacle detection is done by using IR sensors which receives signal from IR transmitter when the obstacle is detected. Light sensing capability is another supporting feature added to the robot for its flexible operation, it is done by using Light dependent resistors.

It is applicable is areas like blocked tunnels, pipe lines and enemy zones which are not reachable due to high risk level, blockage or because of our physical limitations.

This Project is a robot vehicle which is wirelessly controllable through any laptop, it transmits live video wirelessly to the controlling laptop, it can detect obstructions which comes in its path way, and can also sense dark places and efficiently uses its lights to support efficient use of camera even in dark places.

Robot vehicle has the following features enabled:

· Wireless controlled and maneuvered through a laptop using a WiFi link.
· Obstacle detection feature with which any hurdle in its path is detected and the robot stops.
· Wi-Fi enabled transmissionof live digital video to the controller laptop or PC.
· Wireless Live Camera for capturing and transmitted to the PC
· Light sensitivity: It would turn its lights on recognizing if it is dark.
· Audio Sensitivity; It can recognize sound
Temperature Sensitivity: It can recognize temperature

Block diagram of AM transmitter and receiver with explanation

Block diagram of AM transmitter and receiver with explanation AM Transmitter : Transmitters that transmit AM signals are known as AM transmitters. These transmitters are used in medium wave (MW) and short wave (SW) frequency bands for AM broadcast. The MW band has frequencies between 550 KHz and 1650 KHz, and the SW band has frequencies ranging from 3 MHz to 30 MHz. The two types of AM transmitters that are used based on their transmitting powers are: · High Level · Low Level High level transmitters use high level modulation, and low level transmitters use low level modulation. The choice between the two modulation schemes depends on the transmitting power of the AM transmitter. In broadcast transmitters, where the transmitting power may be of the order of kilowatts, high level modulation is employed. In low power transmitters, where only a few watts of transmitting power are required , low...

Using the TLP250 Isolated MOSFET Driver Explanation and Example Circuits

I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...
