    摘要: A linear transport system can have a carriage guide rail having a first and a second carriage, which are arranged in such a way that they can be moved independently of one another on the carriage guide. The XY table for this linear transport system can comprise a carrying structure and a first and a second linear guide, which are embodied with an angular offset relative to one another and each have a first and a second guide element, e.g., which can be moved relative to one another along a linear track. In one arrangement, the first guide elements of the first and second linear guides are connected to the carrying structure. The second guide element of the second linear guide can be connected to the first carriage and the second guide element of the second linear guide can be connected to the second carriage.

    摘要: A motion base comprises lower and upper plates, a plurality of lateral stabilizers coupled in-between and connected to the lower and upper plates, a plurality of actuators, and one or more associated active controllers. Actuators typically comprise a body operatively connected to the upper plate and the lower plate, a rod movably disposed at least partially within the body, where the rod and body define an actuator effective length; and a controllable rod extender configured to selectively extend the rod out from and retract the rod into the body. After determining a desired parameter such as length and an actual parameter such as length, velocity, acceleration, impulse, force, or the like, or a combination thereof for each of the plurality of actuators, a control signal is sent to each controllable rod extender as needed to change the current effective state of that parameter of each actuator by moving each such actuator's extendable rod into or out from each such actuator's body such that the current parameter for each of the plurality of actuators matches the desired parameter for that actuator.

    摘要: In order to obtain a manipulator using a plane pulse motor showing advantageous features such that even in a case where a moment of force is applied to the manipulator in a falling direction, the moment can be sustained by magnetic attraction caused by the pulse motor, the weight of the manipulator is reduced, the degree of freedom of the movement can be increased, and a rotating mechanism for a tool itself is eliminated; a plurality of movable members are provided on a stator of the plane pulse motor, a rotatable shaft is provided on each movable member so as to extend vertically, the rotatable shafts are connected with each other through a connecting member, a required tool is secured to the connecting member, and the movements of the movable members are made controllable in a manner correlated with each other. The manipulator using the plane pulse motor of the aforementioned construction is most adapted to be used in combination with an industrial robot and the like.

    摘要: Milking robot device for automatically milking a dairy animal, comprising a milking box having milking cups and a robot arm having an end effector for applying the milking cups to the teats of the dairy animal, on which milking box the robot arm is suspended above the dairy animal to be milked. The robot arm comprises a first arm part connected to the milking box by a first joint, and a second arm part connected to the first arm part by a second joint and provided with an end effector. The first and second arm part, respectively, is pivotable in a vertical plane with respect to the milking box and the first arm part, respectively, by a first and second actuator, respectively. The end effector is movable within an operating range by the robot arm. The milking robot comprises a weight compensation device having a spring device between the milking box and the robot arm. This is configured to exert a first torque about the first joint and a second torque about the second joint, in such a way that, viewed over the operating range, the first torque compensates for the torque exerted by gravity on the arm about the first joint by at least half, in particular by at least 90%, and the second torque compensates for the torque exerted by gravity on the arm about the second joint by at least half, in particular by at least 90%. Consequently, a compact robot arm is provided, the joints which are suspended relatively high up can be protected from dirt in an efficient manner, and they can be operated using much lighter actuators, so that a great deal of energy can also be saved.
