The disclosure discloses an electric-pneumatic hybrid-driving flexible manipulator with spring framework from plates of special-shaped thickness, including a screw shaft motor, an upper seat plate, guide coupling rods, linear bearings, a driving plate, a push plate, short push rods, connecting rods, a bottom seat plate, flexible fingers, a rotating finger holder, a long push rod, a small support, tension springs, single-head bellows muscles and a ridged push plate. The framework of the flexible fingers is a thickness special-shaped plate spring designed according to the principle of equal strength. In the disclosure, through the control of a motor, an angle between a finger knuckle and a grasped object can be adjusted to realize the adjustment of the position of a contact point. To adjust the position of the contact point of the grasped object, the acting point of the contact force and the direction of the acting force can be selected according to situations, so that the grasping is more accurate and reliable. At the same time, the angle between the finger knuckle and the grasped object can be adjusted to adapt to a larger change in size of the grasped object. In the disclosure, a pneumatic system is large in gain and the pneumatic bellows muscles are light, so that the response is quick and the buffering effect is good.

A robotic trolley collection system and methods for automatically collecting baggage/luggage trolleys are provided. The system includes a differential-driven mobile base; a manipulator mounted on the differential-driven mobile base for forking a trolley, having a structure same as a head portion of the trolley; a sensory and measurement assembly for providing sensing and measurement dataflow; and a main processing case for processing the sensing and measurement dataflow provided by the sensory and measurement assembly and for controlling the differential-driven mobile base, the manipulator, and the sensory and measurement assembly. The method includes localizing and mapping the robotic trolley collection system; detecting an idle trolley to be collected and estimating pose of the idle trolley; visually servoing control of the robotic trolley collection system; and issuing motion control commands to the robotic trolley collection system for automatically collecting the idle trolley.

The present disclosure relates to a parallel variable stiffness actuator. The parallel variable stiffness actuator can comprise a spring and a variable-stiffness mechanism. The variable-stiffness mechanism can be configured to modulate a stiffness of the parallel variable stiffness actuator. The parallel variable stiffness actuator can further comprise a direct-drive motor arranged in parallel with the spring. A force of the direct-drive motor can be applied directly to a load.
