The invention discloses a multi-robot collaborative transportation method. Multiple robots collaboratively drive a target object to a target position; and the types and the quantity of the robots are determined through a central control system or a robot with calculation capacity via a judgment algorithm. According to the multi-robot collaborative transportation method, multiple low-power robots can be used for collaboratively transporting the target object which has the weight higher than the load capacity of the single robot. After the power is reduced, the robots can realize space minimization, thus realizing the advantage that the robots can enter a gap between the object and the ground or enter a gap between the object and another object; and therefore, the storage density of the object is increased, and the special space requirement for a storage device is reduced.

The invention discloses a bagged barium sulfate convenient transfer device in a workshop. Before working, operating personnel firstly place a freight frame on the upper side of a load-bearing seat body; the transfer device is consigned to the position near to-be transferred cargoes; gas in a lifting gas cylinder is released so that the height of the load-bearing seat body can be decreased; the to-be transferred bagged barium sulfate is placed on the freight frame by the operating personnel in a flat lying mode and gradually and continuously overlaid from inside to outside and from low to high till reaches the rated load capacity of a vehicle body; then a driving hand is pushed and pressed in a reciprocating mode so that gas can be inflated into the lifting gas cylinder, and thus the load-bearing seat body drives the cargoes to be ascended to the appropriate height; and the operating personnel consign the vehicle body to a target site through the driving hand, so that transport working is completed. According to the bagged barium sulfate convenient transfer device in the workshop, bagged barium sulfate crystals can be rapidly transferred to the designated site; the cargo capacity is large; control is flexible; the working efficiency of the device is high; and the physical effort of the operating personnel is reduced.

The invention discloses a long-stroke high-precision piezoelectric displacement platform and a driving method thereof. The technical problems that a current piezoelectric stick-slip displacement platform is limited in stroke, unstable in motion and weak in bearing capacity are solved. The micro-displacement platform comprises a fixing base, a driving stator, a bearing sliding block, a top cover, aguide rail, a thread pair, stator mounting screws, top cover mounting screws and guide rail mounting screws. The driving stator extends slowly to drive a flexible hinge to deform through a stacked type piezoelectric ceramic, and continuous feeding of the bearing sliding block is realized by introducing sawtooth wave electric signals to the stacked type piezoelectric ceramic. The platform has thecharacteristics of being simple in structure, high in stability, large in stroke and high in load capacity, and has a good application prospect in the micro-nano driving and positioning fields such asoptical precision instruments and semiconductor processing.
