Three Odisha engineers invent a robotic rescue worker
An eight-year-old boy, Tanmay Sahu, fell into trouble in the central Indian state of Madhya Pradesh while playing with his friends two weeks ago. Although the local police, firefighters, home guards and government disaster response force personnel struggled for 4 days, they were unable to extract the boy alive.
This incident had a great impact on 3 Odia friends working at NMDC in Chhattisgarh, Sisir Mallik, Biren Ku Pradhan and Lingaraj Pradhan.
“We wanted no child to be sacrificed at the altar of travel accidents. So, we decided to invent a device that would help in saving children in such situations. Being electrical and electronic engineering students, we started working on it,” said Sisir Malik, who hails from Jeypore in Koraput district of Odisha. The result was “Borewell Robotics Rescuer”.
The three have teamed up and have now successfully completed their “Borewell Robotics Rescuer” project dummy.
“Once our mission became clear, we started gathering the materials needed for our project and successfully prepared a dummy for the robot. The unit of work at Borewell Robotics Rescuer is that an iron frame will be placed at the top of the pit and then the robot will go down into the pit with the help of an iron cable. The whole process will be controlled by a robotic controller,” told Lingaraj Pradhan who belongs to Krusnapur village in Ganjam district.
There are two wheels on each side which will help him in the process of descending and ascending. When he approaches the trapped child (victim), the camera will capture the entire scenario with the help of a waterproof lighting system. Moreover, there are provisions for a microphone and speaker in the Robot. While approaching the child, the fan at the lower end of the device will provide oxygen to the child, while the fan at the upper end will blow all the poisonous gases out of the hole.”
In the meantime, the child will be positioned with the help of a hydraulic hand and the child will be asked to hold both tubes hanging from the machine. If the child is unable to grasp the whole process or will not be able to hold it, the hydraulic cable will try to hold the child tightly. Then the child will be climbed up and rescued Carefully and slowly.”
The whole process will be monitorable with the help of the camera and loudspeaker.
Hydraulic hand, LED light, camera, speaker, microphone, wheels, oxygen tanks, fans, laptop, etc. used to prepare the equipment.
8 inches wide and 2 feet 6 inches long. It can hold weights up to 50 kg.
“The dummy was created at a cost of RUB 8,000 while the amount required to make the real device would be around £30,000. If there is any kind of help from the government, we can use much better materials for it and create a more sustainable product,” explained Byrne Pradhan Who belongs to Badpur village in Ganjam district.
India has more than 27 million wells. According to the National Disaster Response Force (NDRF), since 2009, more than 40 children have died after falling into wells, and more than 70% of rescues have failed. So, an attempt of this kind is really commendable and of course the need of the hour.
