A six-legged, spider-shaped robot has been developed by the four students of the Sapthagiri College of Engineering in Bengaluru. The hexapod is aimed at helping in search and rescue operations. Using an Internet-connected smartphone it can be controlled from anywhere in the world and features a mic for communication during calamities. The robot can avoid obstacles by itself using an Arduino sensor. It has a 360-degree movable camera with the live streaming feature and sensors which enable it to obtain live temperature and humidity readings. It can be used in nuclear power plants and even for spying purposes in the military. Currently, the cost of the prototype is Rs. 25,000. The students have also created a "Blind man’s Smart Stick" that will help the visually impaired navigate. The device is integrated with ultrasonic sensors and can detect obstacles and water in front, above and below the knee-level of the person. For better aid, the stick produces separate sounds for detecting the two things. Its prototype version costs Rs. 500. Whenever the person uses the remote, a sound will be emitted which can be easily heard by visually challenged people since they have a unique ability to follow sounds.
