After the Sensor Network
Step 2 - Eliminating Weeds and Harmful Plants

After the DNA tests and inventory round is completed, the location of the weeds will be sent by the network hub to another robot-the master robot. The master robot will be the principal farming tool on the farm-it collects crops and weeds, spreads fertilizer, and can plant seeds. The first task of the master robot, once inventory has been taken, will be to travel about the farm, going to the locations specified by the network hub, and picking the weeds. To pick plants, the master robot utilizes a crane like device. This device can not only increase and decrease in height, but it also has various extension which are used to pick plants or weeds. For example, a giant pair of scissors can extend from the edge of the crane and can be used to cut and harvest vines. After picking the weeds, the robot can place them in the large compartment located on the back of the robot for disposal (see figure).
