This is a video showing the automatic probing of plant leaves (to measure chlorophyll) with a robotic arm, using a time-of-flight camera and a spadmeter, which are mounted on top. The first part shows plant probing during the final experiments of the EU project GARNICS, performed with a KUKA robot of the Forschungszentrum Juelich. The second part shows probing with a WAM arm at the Institut de Robotica i Informatica Industrial.
