IIT students build robot to detect cracks in rail tracks
A team of students from IIT Madras have built a robot named 'Artemis' which can detect cracks in rail tracks. The 1.5 foot-long robot is fitted along the railway track and has sensors that can reportedly detect cracks as small as 2 cm. The robot, which can move back-and-forth at a speed of 1m/s, will send out real-time data.
