Abstract: The present invention discloses a pipeline patrol inspection robot having variable tracks and a control method therefor. The pipeline patrol inspection robot of the present invention includes a robot body, track assemblies symmetrically disposed on a left side and a right side of the robot body, and a movement driving mechanism. The robot body is connected to the track assemblies on the left side and the right side by track fixtures, and track angle adjusting mechanisms are respectively connected between the robot body and the track assemblies on the left side and the right side. By means of the present invention, a track camber angle can be adjusted. In addition, each track angle adjusting mechanism is independent, and has desirable flexibility to adapt to different pipeline environments.

Abstract: A monocrystalline SiC substrate comprising a first surface and a second surface. The first surface comprises pinning regions and a device region. Each of the pinning regions is configured to provide a potential well which is capable to attract dislocations from a region surrounding said pinning region. The device region is configured to provide a part of the monocrystalline SiC substrate for manufacturing a semiconductor device. The device region is surrounded by the pinning regions, and a density of dislocations in a central portion of the device region is smaller than a density of dislocations in an edge of the device region due to the pinning regions. The pinning regions surrounding the device region attracts dislocations of the device region into the edge portion, so that the density of dislocations in the central portion is reduced. A yield of the semiconductor devices is improved.
