Abstract: The present disclosure describes systems and methods for maintaining gyroscopic sensor accuracy over time and across changing environmental conditions. In certain aspects, the present disclosure provides arrangements and methods for calibrating a gyroscope while it is positioned on a robotic platform. In particular, the gyroscope may positioned on a sensor platform that is moved through a series of known or measured rotations and then the gyroscope signals are compared to reference data and the sensor's gain and offset calculated. In other aspects, the present disclosure provides arrangements and methods for utilizing measurements from multiple gyroscopes that measure the same axis of rotation.

Abstract: An implement attachment system for a lawn maintenance vehicle includes a box-like structure, where the box-like structure defines a hook configured to cooperate with fasteners located on the lawn maintenance vehicle. A pin is attached to the box-like structure and the pin extends generally downward from the box-like structure. The pin is configured to cooperate with an aperture defined by a portion of an associated frame located on the lawn maintenance vehicle. A resilient force member is attached to the box-like structure. An engagement device is attached to the resilient force member and the engagement device is slidingly attached to the box-like structure.
