Abstract: Systems and methods of unmanned vehicles having self-calibrating sensors and actuators are provided. The unmanned vehicle comprises a communication interface and a processor for controlling a propulsion system of the vehicle and receiving sensor data from one or more sensors of the vehicle. The processor is configured to operate in a guided calibration mode by controlling the propulsion system according to commands received from an external guided control system, while processing the sensor data to determine a degree of certainty on a calibration the sensor data and a position of the vehicle. The processor determines that the degree of certainty is above a threshold value associated with safe operation of the propulsion system in an autonomous calibration mode, and subsequently switch operation of the propulsion system to the autonomous calibration mode based on the determination that the degree of certainty is above the threshold value.

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.
