Technical Perspective:

• Uniqueness in the Robot Design, therefore the robot can be integrated with the existing railway infrastructure easily.
• Said Robot can move on the inner portions of the railway tracks in such a way that railway locomotives can move from above on the same track.
• The system comprises of a carriage base means adapted for being self propelled within a two-rail track.
• A plurality of sensors & the most preferred is an array of ultrasonic, infrared sensors, eddy current based sensors & transducers in between its tires which roll along a rail web adapted for transmission & reception of ultrasonic beams into and from the at least one rail for detection of defects within the rail.
• The system also includes a data acquisition means in communication with the plurality of sensor means.
• The Methods used by the railways for accident deterrence cause disruptions in the regular working of the Indian Railways, causing losses.
• Provide real time solution in terms of real time transmission whenever a crack is detected.
• The transmitted message includes location of the crack & the time of detection.
• Facilitate GSM sim module which works on cellular network, alternatively,

-as a failsafe(in case of network errors) measure the location of the cracks in a SD card using a microcontroller SD card shield.

• Eliminates visual inspection & manual inspection, & save time, secure process, avoid the risk of human lives.

Industrial Perspective:

• The robot design facilitates the addition & usage of equipment for the main purpose (crack detection) as well as for secondary purposes like surveillance.
• This cost-effective design is also completely modular for easy maintenance of the robot.
