With a growing population in the world, more and more food needs to be produced every year. One way to get an increased food production is to use technologies like robots, drones, and satellites to improve the usage of arable land. Satellites and drones can provide accurate data on the soil quality of the different areas of the arable land. This data can be used by robots (self-driving tractors) to plant different seedlings on the land depending on the soil quality. In this way, the seedlings are adapted to the growing environment, which will improve the growth of the seedlings. The mission of the robot is to gather data on the soil quality of the fields of different farms and use this data to plant different seedlings depending on the soil quality.
The Junior Challenge is to make a robot that can plant different kinds of plants in the fields of three farms depending on the soil quality of the fields. There are three kinds of plants represented by three LEGO models:
The Green Farm, the Red Farm, and the Yellow Farm represent the three different farms on the game mat. The green plants must be planted in the fields of the Green Farm, the red plants in the Red Farm, and the yellow plants in the Yellow Farm. Walls protect the fields of the three farms:
The Green Farm is a fertile area so the robot can plant three plants from the Seedling Area on the three fields of the Green Farm. The walls have to be placed in front of the farm to protect the fields of the three farms (see example for the red farm below):
In the Red and Yellow Farms, the robot can only plant red or yellow plants in the fields with a matching soil quality. The robot can retrieve the soil quality of the three fields of the Red and Yellow Farm from the two corresponding areas with Soil Quality Data. In each of the two Soil Quality Data areas, there are three LEGO blocks representing the soil quality of each of the three fields in the Red and the Yellow Farms. A white block represents a field with enough nutrients to grow plants. A black block represents a field without enough nutrients for plants:
