Abstract:
A system, method and apparatus for implementation of variable references frames in unmanned vehicles is provided, which includes an unmanned vehicle comprising: a chassis; a propulsion system configured to move the chassis; sensor(s) configured to sense features around the chassis; a memory storing a global reference frame associated with an environment within which the chassis is to move; a communication interface; and a processor configured to: receive, using the interface, a command to move to a given coordinate in the global reference frame; control the propulsion system to move the chassis to the given coordinate; when the chassis is at the given coordinate, determine, using the sensor(s), that a given feature is detected; and, when so: automatically cease controlling the propulsion system according to the global reference frame; automatically move the chassis according to a local reference frame defined with reference to a point associated with the given feature.
