An actuator system may include a first actuator for being operated by a user, a second actuator for performing a movement of the user, and a transmission channel between the first actuator and the second actuator for transmitting the velocity and the force of the first actuator to the second actuator and vice versa. The actuator system may also include a controller, wherein the controller is configured such that, with the aid of the controller, the energy of the first actuator is adapted to be measured as a desired energy, wherein the transmission channel is configured for transmitting the desired energy to the second actuator and the controller is configured for controlling the damping of the second actuator as a function of the desired energy.

Described herein are systems, methods, and other techniques for controlling a velocity of a construction machine operating within a construction site. Sensor data is captured using one or more sensors of the construction machine while the construction machine is moving at the velocity in a forward or a backward direction. An actual surface of the construction site is estimated based on the sensor data. A deviation between a target surface and the actual surface is calculated. An actual performance metric is calculated based on the deviation. The actual performance metric is compared to a target performance metric to determine a velocity adjustment. The velocity of the construction machine is adjusted by the velocity adjustment.

A method for tying sausages in a rope of sausage using a tying twine supplied from a reel of twine (9) that rotates about the rope of sausage and to which a counterweight (7) is assigned, wherein the counterweight (7) and the reel of twine (9) are adapted to one another when unreeling the tying twine.

A machine tool system and an opening stop position calculating device are provided. The machine tool system includes an openable and closable door for closing an opening of a cover surrounding a machine tool. Furthermore, the machine tool system includes an opening width setting unit for setting an opening width of the door, an opening stop position calculating unit for calculating an opening stop position of the door at which a total time, which is obtained by summing a time required to move the door from a fully closed position to a position of the set opening width and a time required to move the door from an opening stop position where the door is opened and stopped to the fully closed position, is minimized, and a door control unit for controlling opening and closing of the door based on the calculated opening stop position when exchanging the workpiece.

A lathe capable of shortening a cycle time of workpiece machining. A lathe includes a first spindle, a second spindle opposite the first spindle, a tool post on which a cut-off tool is provided, and a control unit which controls rotation of the first and the second spindles and further controls relative movement of the first and the second spindles and the tool post to cut-off the workpiece. The control unit adds a rotation speed fluctuation to a rotation speed of the first spindle after rotating the first spindle and the second spindle synchronously and detects a rotation speed of the second spindle. The control unit determines that the workpiece is normally cut-off upon determining that a detected fluctuation in the rotation speed of the second spindle is within a predetermined range.

A method and a device for curve velocity planning based on NURBS (non-uniform rational B-splines) curve interpolation as well as a numerical control machining route data processing method using NURBS curve interpolation velocity planning are provided. The method includes: obtaining numerical control machining route data with a NURBS curve; obtaining an acceleration within a parameter step length on the NURBS curve; comparing each the acceleration with a maximum allowable acceleration to determine an acceleration sensitive point and an acceleration sensitive interval; determining an intermediate point of the acceleration sensitive interval as a demarcation point of the acceleration and the deceleration; calculating a velocity value of the intermediate point as a target velocity; and planning the acceleration and deceleration of the acceleration sensitive interval based on the target velocity to obtain the numerical control machining route data with the planned NURBS curve.
