A control system for a base supporting a boom assembly comprises long telescopic boom and telescopic stick. Mounted to the remote end of the stick is an end effector that supports a robot arm that moves a further end effector to manipulate the items. The robot arm has a robot base, and mounted above the robot base is a first target in the form of a position sensor, that provides position coordinates relative to a fixed ground reference. Mounted on the end of the robot arm immediately above the end effector is a second target that provides position coordinates relative to the fixed around reference. The fixed ground reference tracks the sensors and feeds data to the control system to move the stick with slow dynamic response and to control movement of the robotic arm and end effector with fast dynamic response.
