A shooting stand with a balancing weight includes a standing frame, a top base, an installing support, a telescopic member, a guide wheel, a rope and a balancing rod. The balancing rod is hinged with the top base, and the balancing rod is extended along a direction away from the top base, the rope goes around the guide wheel, one end of the rope is connected to the telescopic part or the installing support, and the other end is connected to the balancing rod away from the top base. When the telescopic part is extended, the rope is pulled to cause the balancing rod to pivot to approach the cantilever arm; when the telescopic part is retracted, the rope is loosened to cause the balancing rod to pivot away from the cantilever arm, and the rope is pulled to move again. The stability and reliability are improved.

A facility for automated modelling of the cutting process for a particular material to be cut by a beam cutting tool, such as a waterjet cutting system, from empirical data to predict aspects of the waterjet's effect on the workpiece across a range of material thicknesses, across a range of cutting geometries, and across a range of cutting quality levels, all of which may be broader than, and independent of the actual requirements for a target workpiece, is described.

A gimbal includes a control device configured to receive an action instruction including a press action instruction and, based on the action instruction, generate a control instruction including a switch control instruction for switching operating modes of the gimbal, a controlling assembly configured to receive the control instruction and generate a performing instruction based on the control instruction for controlling an optical device, and a performing assembly configured to receive and implement the performing instruction. The performing assembly is operably connected to the controlling assembly and supported on a top end of a support arm of the control device. The performing assembly comprises a first rotation member, a second rotation member, and a carrying member connected one to another, and first and second motors for driving the second rotation member and the carrying member to rotate relative to the first and second rotation members, respectively.
