Abstract: An example sensor assembly includes: a rotary displacement amplifier configured to be coupled to a lap bar of a mower and configured to amplify movement of the lap bar; and a rotary sensor comprising a sensor shaft coupled to, and rotatable by, the rotary displacement amplifier, wherein the rotary displacement amplifier is configured to transmit an amplified movement of the lap bar to the sensor shaft, and wherein the rotary sensor is configured to provide a signal indicative of a rotary position of the sensor shaft to a drive motor controller of the mower to drive an electric motor based on the signal.

Abstract: A system and method is provided for traversing inside one or more pipes. In an embodiment, a fluid is injected into the one or more pipes thereby promoting a fluid flow. An inspection device is deployed into the one or more pipes at least partially filled with a flowing fluid. The inspection device comprises a housing wherein the housing is designed to exploit the hydrokinetic effects associated with a fluid flow in one or more pipes as well as maneuver past a variety of pipe configurations. The inspection device may contain one or more sensors capable of performing a variety of inspection tasks.
