| 20100318321 | PEDESTAL NAVIGATION SYSTEM - This invention provides a pedestal for a TV, video or cine camera comprising a base supported on at least three steerable wheel units, a steering system for the wheel units for maintaining the wheel units in parallel alignment with one another, a monitoring system for the wheel units and the steering system, and means for determining the distance moved by each wheel unit and the angle steered in relation to a fixed axis defined on the base. The monitoring system having processor means for calculating from the distances moved by every one of at least three wheels and the angle steered by every one of the at least three wheels in relation to the fixed axis, the trajectory distance traveled and any change of orientation of the pedestal to enable the position and orientation of the pedestal to be determined in relation to a previously known position and orientation. | 12-16-2010 |
