Abstract: A battery powered lawnmower having a blade motor coupled to at least one blade, a user input device configured to receive a blade motor control signal and a bail control bar. The bail control bar is coupled to a position sensor configured to determine a position of the bail control bar. The battery powered lawnmower further includes a controller coupled to the position sensor and configured to control an operation of the blade motor. The controller is configured to receive a blade motor control command and determine a position of the bail control bar based on data provided by the position sensor. The controller is further configured to, in response to determining that the bail control bar is in a closed position, control the blade motor based on the received blade motor control command.

Abstract: A lawnmower may include an inertial measurement device configured to capture data indicative of an orientation of a housing of the lawnmower. The lawnmower may also include a controller coupled (i) to a motor configured to rotate one or more cutting blades and (ii) to the inertial measurement device. The controller may be configured to receive, from the inertial measurement device, the data indicative of the orientation of the housing. The controller may be further configured to determine a three-dimensional position of the housing based on the data. The three-dimensional position of the housing may indicate whether the orientation of the housing is desirable for operation of the lawnmower. The controller may be further configured to control the motor based on the three-dimensional position of the housing.
