Abstract
While a crawler body,is traveling, infrared sensors,and an elevational difference calculator,incorporated in a controller,detects the magnitude of a step present ahead of the crawler body,. A safety speed calculator,calculates a safety speed based on the magnitude of the step detected and on the position of the platform,relative to the crawler body,, which position is detected by various detectors,and by a position calculator,. A comparator,compares this safety speed with the traveling speed of the crawler body,, and if the current speed of the crawler body,is greater than the safety speed, then the comparator,outputs a warning signal. Upon receiving this signal, a restrictor,controls a valve controller,to reduce the speed of the crawler body,such that the crawler body,can travel over the step safely.
