Robot destroyed during testrun of the LHC

Today the LHC performed one of its atomic collision test. The goal was to validate the results of the last test run. During this test the  Large Hadron Collider produced a never seen amount of energy. Therefore  many skeptics said that the results where totally wrong because of the uncertainty principle. So this last test run tried to validated the results by using subatomic robots inside of the LHC to observe the collision and measuring the energy directly instead of indirect.

The approach failed by destroying the robots at four o’clock  and one minute this afternoon. One of the robots collided with the atom instead the other proton. Its remains where found 4,1 kilometer outer the the two thousand and tenth epipolar collider shield.

John Robinson Pierce was born in March 27, 1910 Des Moines – Iowa and died at April 2, 2002 in Sunnyvale – California. During his life time was he an expert in the fields of radio communication, microwave technology, computer music and psychoacoustics. His team developed in the year 1949 the first transistor. This pioneer work allowed the building of modern digital computers and robots, as well as nearly all digital components of our every day life.

For those that would like to learn more about this pioneer we recommend flowing artikels:

So, RoboBlog says happy birthday and thank you.

Interesting designs for Rescue Robots – Part 1

Robot rescue is one, if not even the one, upcoming field for robotics. It is not new, but at present many teams and projects around the world are showing up with new ideas and solutions (e.g. NIFTi, CRASAR). So I will start to collect a few interesting approaches, and present them here on RoboBlog.

So our first candidate is the „Bari-bari II“ robot. It is developed by the Tokyo institute of technology and designed to help rescue workers by lifting heavy boulders / plates.

The capabilities are shown in the following video:

The interesting point is not that the robot can lift heavy material. That can be performed by many robots. The most robot systems that can lift material make usage of either a physical manipulator (hand or arm like) or of a blade (like we have presented earlier on this Blog: RoboPlow). But as fare as i know there is not a single one that is designed i such a way that the hole system itself if part of the lifting unit.

By side of all enthusiasm, some questions are still open:

  • The „Bari-bari II“ is presented as a tool to crawl under a plat or similar stuff. To do so it makes some maneuvers of lifting and singe off. What is about preventing against more collapses?
  • If there is now a victim below the plate, he or she will also fell the pressure of the lifting and singing. But as fare as i know, this is not wise. Victims, which are stuck should only be moved as much as needed and you shout never remove the pressure from him or here if you can not eminently support him/here by medicine. During the suck time the blood can often not circulate freely. This causes clumps of blood component. If the pressure is released the blood starts to circulate freely trow the whole body and the clumps can jam haemals. This can causes thrombosis which can lead up to death.
