A robotic terminal effector for automatically installing an insert in a cavity provided in a sandwich type panel made of composite material with a cellular core, said insert comprising an upper flange comprising a resin inlet orifice and a resin outlet orifice, said effector being intended to be mounted on a carrier, for example, a robot arm, and comprising:
- a contact body having a contact surface;
- the contact surface comprising:
- a means for injecting resin into an empty space delimited by the insert and the cavity when the insert is positioned in the cavity;
- and
- a means for grasping the insert by suction;
- said resin injection and grasping means being configured in such a way as to leave the contact surface free to be pressed against an upper face of the composite panel by a set of pressing means, so as to generate a continuous sealed zone around the cavity while the insert is being installed in the cavity.
