Safeguarding Robotic teleoperation system for Furnace environment
Steel mill is one of the most extreme and hazardous working environments due to molten iron erupted from blast furnace. Current manual labor to remove lump iron near outlet, which is essential to prevent lump iron from scattering or blocking of molten iron, is performed by equipped human worker using long stick tool.
Thus, implementation of robotic teleoperation system is in demand to ensure safety of worker.
However, conventional command interface is not intuitive for tool manipulation (i.e. pivoting, sweeping).
Besides, haptic interface, which is used to render interaction result efficiently, still limits performance due to narrow workspace and insufficient kinesthetic feedback output compared to requirements.
Fixed type has large workspace and high kinesthetic feedback output satisfying requirements.
Further, Floated type has strength with unlimited workspace at the expense of amount of haptic information from simple vibrotactile feedback.
