Proximity Senor: Proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.It has the following standard features: 8K bytes of flash, 256 bytes of RAM, 32 I/O lines, watchdog timer, 2 data pointers, 3 16-bit timers/counters, on-chip oscillator and clock circuitry. This is a powerful microcontroller which provides high flexibility and cost effective solution to many embedded control applications. AT89S52: The AT89S52 is a low power, high performance CMOS 8-bit microcontroller with 8k bytes of in-system programmable flash memory.Solar energy is used to run the robot wheels of DC Motor.The Crack is detected by the IR Sensor, the controller get the signal,the robot model is stopped on the track,it has the buzzer.The GSM modem can be added to the robot so the crack is found means the message will be sent to the track man or corresponding near station, the train can be alert track which train is on the track. To avoid these accident the automation technology is implemented on the railways system like Automated railway crossing level technology and here the crack can be detected by this technique. The most accident is occurs in the level crossing at the track and the crack break there produce a massive disaster in railways many people are died in that accident,even economical loss government. Robotics Kit will be shipped to you and you can learn and build using tutorials.
