Research output: PatentOther research output


A plant detection device is provided that includes a robotic arm having gripping element that includes first and second curved grippers with opposing concave surfaces that move between an open and closed states, and the arm moves and vibrates the gripping element, a proximity force sensor that is disposed on the gripper and outputs a measurement signal of a force between the gripping element and an outgrowth from a stem of a plant under test to a computer, a force and frequency sensor that is orthogonal to the proximity force sensor outputs a gripping force measurement and a frequency response measurement of the stem of the plant under test to the computer, where the computer moves the gripping and vibrating arm according to the sensor signal outputs.
