Two-wheeled inverted pendulum (TWIP) vehicles are prone to lose their mobility and postural stability owing inherently unstable underactuated dynamic characteristics, specifically when they encounter abruptly changed slopes or ground friction. Overcoming such environmental disturbances is essential realize an agile TWIP-based mobile platform. In this paper, we suggest a disturbance compensation...

The elevated temperature tensile behavior of a Nb-Mo microalloyed medium steel was investigated over the ?50 to 150 °C range. ultimate strength significantly reduced with increasing deformation temperature, but both YS (yield strength) and EI (total elongation) values changed slightly. best product UTS (ultimate (~59.5 GPa·%) can be achieved at 50 °C, implying an excellent combination ductility...
