Pruning robot for removing processionary caterpillar nests

A weeding robot comprising:

• a flying drone, the flying drone comprising an on-board automaton;
• an articulated gripper arranged to grip the flying drone with a branch supporting a nest to be eliminated,
• a cutting device mounted on the flying drone, the cutting device being configured to cut a branch supporting a nest to be eliminated,
• a drone's inertia control unit, wherein
• the on-board automaton is equipped with a horizontal support pole carrying the cutting device,
• centering of the weeding robot is adjusted by the drone's inertia control unit aided by a counterweight including a battery for powering the robot,
• the cutting device comprises a circular saw rotated by a first electric motor, the circular saw including a rotating cutting disc projecting forwardly with respect to the first motor,
• the articulated gripper is arranged under the cutting device, the articulated gripper being actuated by a second electric motor driving two jaws of the motorized articulated gripper between a closed position and an open position, and
• the articulated gripper is supported by a first cylindrical tube configured to slide in a second tube of a frame to guide the articulated gripper forwards or backwards under an action of a control mechanism of the first actuator, the frame being mounted so that the frame can pivot about an axis of the pole on a ball bearing.
