Abstract: A working vehicle includes an engine, a pair of right and left traveling portions rotated by a power of the engine, a pair of right and left brake operation devices for respectively operating to brake the traveling portions, an engine controller which controls driving of the engine, and a control mode selection switch which can alternatively select the isochronous control and the droop control. The engine controller selects any of an isochronous control and a droop control so as to control the engine. In the case that the isochronous control is designated by the control mode selection switch, the engine is controlled according to the isochronous control when one of the right and left brake operation devices is under a non-operation state, and the engine is controlled according to the droop control when both of the right and left brake operation devices are under an operation state.

Each of the link mechanisms includes a proximal side end link member, a distal side end link member, and an intermediate link member. A line member is disposed between the link hubs, two ends of the line member being held at line member holding points which are on link hub central axes, respectively. In a state where the link hubs are parallel to each other, when the distance from a midpoint to each spherical link center is defined as (D) and the distance from each spherical link center to its corresponding line member holding point is defined as (H), the relationship H=0.5×D is established.

Abstract: A link actuation device includes a distal end side link hub connected with a proximal end side link hub through three or more sets of link mechanisms for alteration in orientation. By means of an actuator provided in the two or more set of the link mechanism, the distal end orientation, which is the orientation of the distal end side link hub relative to the proximal end link hub, is changed arbitrarily. The operating device includes an orientation designating unit for designating the distal end orientation aimed at by means of a coordinate position on the orthogonal coordinate system by an artificial manipulation, an orientation acquiring unit for acquiring the distal end orientation that is expressed by an angular coordinate system through calculation, and an orientation information applying unit for applying information on the distal end orientation so acquired to a control device for controlling the actuator.

Abstract: In this link actuation device, arms of a plurality of link mechanisms are driven to be rotated by actuators, whereby the posture of a distal end side link hub is changed. A divided section setter divides a trajectory on a work surface on which an end effector works, into a plurality of sections at pass points and sets the sections. An arm rotation speed calculator calculates a rotation speed at which each arm performs constant speed rotation in each section on the basis of: a time period of movement in the section which is determined from a target moving speed and the distance of the section; and a rotation-angular movement amount of the arm in the section. A posture change controller performs positioning control on each actuator so as to cause its corresponding arm to continuously rotate at the corresponding rotation speed without acceleration/deceleration.

Abstract: A remote controlled actuator includes an elongated spindle guide section and a distal end member fitted to a distal end thereof for alteration in attitude. The distal end member rotatably supports a spindle for holding a tool. The spindle guide section includes a rotary shaft for transmitting rotation of a tool rotation drive source to the spindle. An attitude altering member inserted in a guide hole is selectively advanced or retracted by an attitude control drive source. An initial attitude hold control unit controls the attitude control drive source so that an initial attitude holding force necessary to maintain the distal end member in the initial attitude can be applied to the attitude altering member. An attitude alteration control unit controls the attitude control drive source so that the attitude of the distal end member can be altered by a force larger than the initial attitude holding force.
