Abstract: A waste sorting robot comprises a manipulator moveable within a working area. A suction gripper is connected to the manipulator and arranged to selectively grip a waste object in the working area. An air supply is in fluid communication with the suction gripper and configured to generate an airflow along an airflow path in the suction gripper. A solvent outlet in fluid communication with a solvent supply wherein the solvent outlet configured to dose the airflow with the solvent.

Abstract: A waste sorting robot can include a manipulator comprising a suction gripper for interacting with one or more waste objects to be sorted within a working area, and wherein the manipulator is moveable within the working area. There is a controller configured to send control instructions to the manipulator. At least one pressure sensor is in fluid communication with the suction gripper and configured to generate a pressure signal in dependence on a fluid pressure in the suction gripper. The controller is configured to receive the pressure signal and to determine manipulator instructions in dependence on the pressure signal.
