  • Patent number: 11938619
    Abstract: An adjustable seedling pick-up end effector for automatically transplanting plug seedlings is provided includes two clamping fingers installed symmetrically along a direction of a center line, support frames respectively connected adjustably to the clamping fingers, and a mechanical arm fixedly connected to the support frames. The mechanical arm is constructed to drive a clamping pin mechanism to execute actions of prying, grabbing, and quickly releasing the plug seedlings, and the adjustment of the opening degree and the clamping angle of the clamping pin mechanism is realized by adopting the adjustably connected support frames. The end effector can be actively opened and closed to grab and release the plug seedlings, provide a larger space to accommodate the plug seedlings so as not to damage the seedlings, and adjust the opening degree and the clamping angle, which can meet the seedling pick-up requirements for automatic transplanting of plug seedlings of various specifications.

  • Patent number: 8144872
    Abstract: A system and method for generating analog-digital mixed chaotic signal and an encryption communication method thereof are provided. In the system and method, the complementarity between continuous chaotic systems (12, 22) and digital chaotic systems (11, 21) are reasonably utilized. In specific, the digital chaotic systems, which are separated from each other, control the local continuous chaotic systems respectively, so as to enable the continuous chaotic systems, which are also separated from each other, to stably and synchronously work for a long time. Thus, there is no need to transmit the synchronizing signal, and as a result the anti-attack capability is increased effectively. Further, the continuous chaotic systems disturb the local digital chaotic systems to prevent the digital chaotic systems from degradation. This compensates the drawbacks of digital chaotic systems.
