A robot to inspect gas and water pipes

Pipe Robot

Too often, small accidents at home or at work turn into real disasters, with a catastrophic outcome, because of water or gas pipes that are too old, damaged or worn out, which may have leaks invisible even to the most accurate of inspections. This kind of leak, in case of an accident, may turn out lethal.

In order to inspect metal pipes, the Tokyo University of Electro Communications has created a robot for pipe inspection, which can easily move inside metallic tubes with a diameter of at least 10 centimeters, by simply using a magnet to remain stuck to the pipe’s walls.

Aside from the magnet, it is also equipped with a digital camera, a battery and a LED light. Thanks to this equipment, the robot is capable of moving on four small wheels within the pipe, of illuminating it with its light and using a connection cable to transmit the images towards a personal computer, from where the entire inspection operation is monitored.

The initial prototype created by Japanese researchers can be controlled remotely, and the vibrations created by the magnet, which moves like a pendulum, keep the robot stuck to the inside of the pipe, and allow it to move freely, even vertically.

Its small size (11 cm in length, with a width and height of 8 cm) makes it suitable for most gas and water pipes, thus eliminating the need of digging or breaking into a wall, as the robot can be inserted into the pipe at any point, connected to the computer and you are ready to go, without additional costs or uncomfortable working conditions during the inspection of your pipes.

Hydrogen fuel cell UAV breaks endurance record

Ion Tiger

The US Navy Naval Research Laboratory has just completed the test of a new kind of UAV (Unmanned Aerial Vehicle) which, thanks to a battery powered by hydrogen, has been able to fly for 26 full hours without any interruption, while carrying a small payload weighing approximately 2 kg.

The Ion Tiger vehicle, apart from using a hydrogen cell as a high-energy fuel, also relies on al electric propulsion system, which guarantees a complete absence of noise during its operations. The system’s total weight is approximately 17 kg, and it can carry a payload of up to 2.5 kg. Its hydrogen fuel cell provides approximately 550 Watt power, which is around 7 times the energy supplied by a conventional battery of the same weight.

Aside from low energy consumption, the possibility of operating silently makes it perfect for applications which require flexibility and quick operation, and most of all, extreme confidentiality. Thanks to these characteristics, the Ion Tiger unmanned vehicle is perfect for aerial video surveillance operations, even in long range.

The result achieved by Ion Tiger, with a continuous flight time of 26 hours and 1 minute, breaks the previous record, held by the same vehicle, which during an unofficial flight was in the air for 23 hours and 17 minutes.
Furthermore, this record almost triples the result obtained by the hybrid-powered SUAV (Small Unmanned Aerial vehicle) Puma, which only one year and a half ago flew for 9 hours; Ion Tiger’s achievement also functions as an indicator of the huge potential of hydrogen fuel cell power for this kind of vehicles, which can be used in several fields such as security, aerial reconnaissance or scientific aerial photography.

Exploding mines and Peaceful Mind

Unlimited GSM transmitter

Mines were exploding and Mr. Hardweister was smiling happily. He was in-charge of a major construction activity that, when completed, would change the traffic scenario of the city.

Though the city housed only 3 million people, I couldn’t contain the vehicles flooding and choking the Grant Road that linked city to the industrial hub and airport. But this life line of the city was choking. It was unable to carry the influx of vehicles especially during office hours. Almost every commuter was troubled by the chaos and lost productive hours in transit.

Mr. Hardweister was working on the solution – Modern Link Road! It was to be constructed by digging across a rocky mountain that stood opposite to the airport. He had to travel several times between the city office and the worksite. And that was his point of worry. He was sure that the workers will perform in his presence, but what after he departs for the city office? The worry made him restless as the project had strict deadline to follow.

He has always been a solution seeker, so it hardly took him any time to decide what he wanted. He took resort to a device called Infinity GSM Triband, an Unlimited GSM Transmitter. It utilized SIM to access across any GSM network. By dialing the number it allowed to listen sound or voice in the background from anywhere in the world.

Now, Mr. Hardweister could anytime listen to the mines exploding!
