Abstract: Methods, systems 1 and devices such as robots 8, 9 for farming are disclosed. An autonomous monitoring robot is configured to traverse a farm plot and generate, from a sensor set of the monitoring robot, a farm plot data set. The farm plot data set is processed to generate operating instructions for a tending robot. The tending robot is arranged to execute the operating instructions so as to traverse the farm plot and performs tending tasks on it including such as seed-planting, weeding, and applying crop treatments such as fertiliser, fungicide, herbicide or pesticide.
