Abstract
An apparatus, method, and system of self-calibrating sensors and actuators for unmanned vehicles is provided, which includes an unmanned vehicle comprising: a chassis; a propulsion system; one or more sensors configured to sense features around the chassis; a memory; a communication interface; and a processor configured to: operate the propulsion system in a guided calibration mode; automatically switch operation of the propulsion system to an autonomous calibration mode when a degree of certainty on a calibration of one or more of sensor data and a position of the chassis is above a first threshold value associated with safe operation of the propulsion system in the autonomous calibration mode; thereafter, operate the propulsion system in the autonomous calibration mode; and, automatically switch operation of the propulsion system to an operational mode when the degree of certainty is above a second threshold value greater than the first threshold value.
