Abstract
A first sensor detects a boom position of a boom based on a first linear position of a first movable member of a first hydraulic cylinder. A second sensor detects an attachment position of an attachment based on a second linear position of a second movable member of a second hydraulic cylinder. An accelerometer detects an acceleration or deceleration of the boom. A switch accepts a command to enter a ready position state from another position state. A controller controls the first hydraulic cylinder to attain a target boom position and for controlling the second cylinder to attain a target attachment position associated with the ready position state in response to the command in conformity with at least one of a desired boom motion curve and a desired attachment motion curve.
