Patent attributes
A reaction compensated steerable platform device is disclosed. The reaction compensated steerable platform device can include a base, a steerable platform movably coupled to the base, and a reaction mass movably coupled to the base. The reaction compensated steerable platform device can also include a primary actuator to cause movement of the steerable platform, and a trim actuator coupled to the reaction mass and the base. In addition, the reaction compensated steerable platform device can include a sensor configured to provide feedback for actuation of the trim actuator. The reaction mass can be configured to move by actuation independent of the trim actuator to compensate for a first portion of a load induced by the movement of the steerable platform. Actuation of the trim actuator can be controlled by the sensor, such that the reaction mass moves to compensate for a second portion of the load induced by the movement of the steerable platform.
