Abstract: An action force being inputted to an object dynamic model (2) is determined such that the motion state amount (object model speed) of the object dynamic model (2) follows up a target motion state amount based on the movement schedule of the object, manipulated variable of the motion state amount (object model speed) of the object dynamic model (2) is determined such that the difference between the actual object position and the target object position approaches 0, the action force and manipulated variable thus determined are then inputted to the object dynamic model (2) thus determining the target object position sequentially. Furthermore, a target object reaction from the object to a robot is determined from the action force thus determined. Consequently, the robot performs a work for moving the object while ensuring stability of the robot by determining the target motion of the object and the target action force between the object and the robot while reducing deviation of actual motion state from the motion state of the object on the object dynamic model.

IPC: F42B10/14
Filed: 2006-01-23
Abstract: A missile (10) has fins (12) that rotate about a single axis to deploy from a stowed position to a deployed position. A foil longitudinal axis (24) of each fin (12) is angled relative to a shaft (28) of the fin, such that a single-axis rotation of the shaft (28) moves the foil (12) from the stowed position to a deployed position. A coil spring (36) may provide both torsion and compression forces to rotate the fin (12) into the deployed position and lock it into place. Torsion rotates the shaft (28) until it reaches a seat on a bushing (34) that is around the shaft (28). Then compression forces from the spring (36) engage a keyed protrusion (46) on the shaft (28) with a corresponding keyway (56) in the bushing (34), locking the shaft (28) in place. There may be an additional lock once the fin (12) is deployed, such as a spring-loaded pin (94) in the missile body (16) that engages a depression (51) in the shaft (28).
