Dandelion weed picker for your yard

The project is to build a robot just like the vacuumed robot which will pick dandelion (grass weed) from the yard. The robot needs to first map the yard of the property based on different type of material like Asphalt, Grass, Stone, Concrete using the image processing. It will avoid any obstacles if encountered. We should be able to see the robot location at any time on the computer or mobile phone. Once the robot is finished mapping the yard it will return to original point/charging point. At any point If the battery gets low the robot will return it its original point/charging point. Once the yard mapping is completed, it will split the yard into different zones based on the material. At this point you can select any zone and the robot will go to that zone and start looking for a Dandelion plant and will use its robotic arm to pick it from the ground. We should be able to check how much area robot has already completed on computer/mobile phone.
