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.
