Abstract
Calibration of a hexapod structure includes measuring a head pose of the hexapod structure relative to a base of the hexapod structure. Calibration of the hexapod structure also includes for each strut, independently increasing a length of each strut by a predefined amount from an original length and repeating the measuring of the head pose relative to the base. Calibration of the hexapod structure further includes for each strut, independently decreasing a length of each strut by a predefined amount from the original length and repeating the measuring of the head pose relative to the base. Additionally, calibration of the hexapod structure includes moving each strut back to the original length, and estimating joint errors for each strut prior to calibrating of the hexapod structure.
