According to the Science and Technology Daily report, near the Spring Festival, Liu Ziheng, a freshman of Tianjin University's intelligent medical engineering major, used his brain-controlled mechanical arm to hold a brush and ink to write the word "Fu". He was surprised to sigh that he had grown three heads and six arms. Let him have such a "hands-on" is Tianda's independent research and development of the world's largest instruction set high-speed brain-controlled intelligent arm robot "Where."
Legend has it that the brave sea is located in the mouth of the Sancha River in Tianjin. Today, the "three heads and six arms" of the temple are transformed from myth to reality in Tianjin University. This brain-controlled robotic arm system called "Where" is the latest achievement of the brain-computer interface (BCI) series independently developed by the Tianda Neuroengineering team. The technology creates a current scalp by creating an ultra-short SSVEP (200ms) and P300 brainwave efficient fusion paradigm, designing a time-frequency-phase hybrid coding brain-computer interaction information strategy, finely deciphering and fast decoding for very weak EEG features. EEG BCI online control of the world's largest instruction set (108), the highest information transmission rate of 238bits / min. Relying on the above key technological breakthroughs, the “Where†robot system deciphers the “author†EEG cipher, transforms the view pixel command map of the brain control stroke topology into the 6D space coordinates of the intelligent robot arm, and realizes the BCI information for the first time in the world. The output method has changed dramatically from “spelling†to “writingâ€.
In the next step, the function of the brain-controlled intelligent arm robot system will be further improved and expanded, and it will play an important role in promoting the development and application of a new generation of human-machine hybrid intelligence and human-computer interaction in the fields of clinical medicine. In the aerospace and special military and other occasions, “Wenyi†will also provide the “third hand†in the limb restraint environment for special people, helping them to have an “arm†force at the critical time to complete more and more complex tasks. .
The gas protection Welding wire is a type of copper-plated low alloy steel gas shielded welding wire, using carbon dioxide or argon-rich as the shielding gas for welding. It has excellent welding process performance, stable arc combustion, less spatter, beautiful weld forming, small sensitivity of weld metal porosity, good welding technology in all position, and can be suitable for a wide range of welding current.
