Seed handling and seeds of the three species investigated here. A, Tool change head (TCH) at the robot arm to which, by the aid of a tool change adapter (TCA), an exchangeable seed-handling tool (EXT) is fixed. A pressure sensor (P3), solenoid valve (V2), and dedicated nozzle (Nz) also are shown. B, Screen shot of temporal pressure changes near the nozzle as measured by P3. The denoted phases 1 to 3 and the arrows are described in detail in the text. C to E, Seeds sucked at the nozzle are shown for Arabidopsis (C), rapeseed (D), and barley (E). Bars = 1 mm.
