A manipulative device capable of remote operation has a nozzle head (1) having one or more nozzles adapted to eject a fluid stream having a component at right angles to the axis of the nozzle head. There is a flexible elongate hose (2) for connecting the nozzle head to a source of remote operation, such as a joystick arrangement (9). Also valves (6) capable of operation by tendons (3) parallel to the flexible elongate hose enables spatial positioning of the nozzle head by remote differential operation of the tendons. The device may be used in various application for example borehole mining, paint spraying etc. |
