The advancement in the field of automation along with the mechanical design has a great impact on the society. The objective of the project is to design and construct a “Bore-well rescue robot” (i.e. to rescue a trapped baby from borewell). This project includes series of process development from hand drawn sketches to computer generated design. The modern equipment’s were implemented for various parts of the machine, since the machine performs a life rescue activity.
The light weight servo motors were implemented for the machine operations. A safety balloon was introduced in order to provide extra safety. A long range CCTV camera was placed to find the baby position. An additional fork system was implemented for the perfect positioning. This machine is a human controlled computerized machine system with additional safety devices.
In the present era, robotic technologies combined with rapid advances in electronics, controls, vision and other forms of sensing, and computing have been widely recognized for their potential applications in almost all areas. There were so many child deaths due to the open bore-wells. The children fell into the open bore-wells and the rescue operation was almost end with failure. In the present what we do is dig a new well of the same depth next to the bore well and then make a tunnel connecting the two. This is a time consuming and costly process. It may take hours or even days to dig new well. In India there were frequent bore-well deaths. Approximately 20 children were felt in the bore-well and only 2 were alive. To overcome these hurdles, we have designed a bore-well recue robot with advanced equipment and devices.
Closed-circuit television (CCTV) is more suitable for live-monitoring purposes. CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
· The respiration of human beings will difficult, if the percentage of oxygen in air becomes less than 18%.so, we need a device to supply proper oxygen to the baby at the rescue process.
· An oxygen concentrator is placed on the surface of the bore-well. It will automatically sense the defect of oxygen at the rescue region and it supplies the required oxygen. For this purpose, we included oxygen concentrator.
· An oxygen tube of 200 meter is placed on the surface.
· The tube is sent along with the robot to supply emergency oxygen to baby.
· The figures 2 and 3 show the oxygen concentrator and oxygen hoses.
Step 1: The stand and pulley setup is placed exactly in centre of bore-well hole using carpenter’s level.
Step 2: The rope is connected to the top of robot.
Step 3: As the robot is sent into the bore-well hole, electric wires for the motor from the control unit chip is attached along the rope.
Step 4: The oxygen hose is fixed to the upper plate of robot. Depending on the robot movement, the hose length is adjusted from outside the bore-well.
Step 5: The gas hose from the compressor is connected to the gas box located on the lower plate through the hole in upper plate. The gas box act as an intermediate gas transmitter.
Step 6: Depending on the robot motion, the rope is sent into the bore-well hole by a 3 pulley control system. The largest pulley is connected to motor shaft. Using this, the rope is pulled or pushed from the hole.
Step 7: Using the motion detector and other special features of camera, the baby position is seen through computer.
Step 8: At the appropriate position, the fork will punch into the bore-well wall using the motor connected to the bevel gear setup on the upper plate.
If the baby is trapped in the middle of bore-well, the following steps should be done.
a) Using the motor connected at lower end of the hollow tube, the lower plate is rotated in such a way the safety balloon gas tube is in the gap between bore-well and the baby.
b) Initially the gas tube is above the end of robot hands.
c) It will avoid stabbing of gas tube on the baby.
d) Using the motor connected to the pinion, the rack is moved lower than the robot hands.
e) Then the robot is moved down in such a way that the robot hands free to hold the baby head or middle of the body.
f) Then using the individually working screw type gear system under the lower plate, the hands of robot are moved depending on the baby posture.
g) During holding, the strain pressure of the baby is measured using the pressure sensor connected the robot hands.
h) The pressure sensor output of each hand is shown in the separate multimeter.
i) The multimeter is placed on the lower plate in convenient to see the pressure changes through the other camera connected in middle of the hollow tube.
j) Now the baby is safer in between the robot hands.
k) Then the temperature of the baby and surroundings is measured through the Digital thermometer which is controlled in the computer.
l) The display of the thermometer is also placed under the upper camera along with the multimeter.
m) Then the safety balloon is inflated by using the air compressor through gas box. The air pressure is measured in analog pressure gauge connected to the compressor.
n) For extra safety, a Digital pressure gauge is connected at the junction of the rack, safety balloon filling pipe and the hose from the gas box.
o) The Digital display is placed below the upper camera.
p) After the safety balloon reached the exact pressure, the compressor is cut off.
q) Then the safety balloon is moved upward using motor connected to the rack and pinion setup till the safety balloon completely supports the baby.
r) Now the baby is completely in robot control.
s) The baby movements are seen through the lower camera and other data readings are seen through upper camera.
t) The two way audio communication will help us to know the stipulations of the baby.
u) Then slowly, the baby is moved upward by pulling the rope using the pulley control system.
v) The medical team will be able to prepare for the treatment depending on the already seen temperature of the baby.
w) When the robot is pulled out, the rope is cut off.
x) The robot is taken outside carefully from the stand.
y) The hands are loosening by the motor control and the baby is taken for treatment.
z) Thus the baby is rescued within 30 minutes with full advanced robot system.
If the baby is at the end of the bore-well, the following steps should be done.
a) It is similar to the above method with one step alternation.
b) The gas tube is above the robot hands as like the above procedure.
c) But the first rescue step is to hold the baby and lift the baby to at least 30 centimeter.
d) Then the gas tube is lowered using rack and pinion setup.
e) Then all the procedures are similar to the above case
· Thus we tried our level best to create a successful bore-well rescue robot. Since the actual robot cost is high, we designed in computer and we made it as model with few features excluded from the original proposed robot.
· The proposed system of rescue operation was better than ordinary rescue operation.
· The proposed machine has several devices to do specified work which will make the robot more efficient and in safety manner.
· If we get sponsor from government or private organization, we will make the actual robot.
· Since the proposed model has only few modifications and more advantages, it surely improves the rescue operation with less time.
· We still working on this project to include few modifications and to produce 100 % efficient bore-well rescue robot to the society.
