Grab & Drop

This scenario was mainly created for kids. The main aim of creating the scenario was to make kids develop an early interest in robot programming, this allows them to start learning about the vital concepts needed to understand robot programming and possibly pursue a career along that path.
In the scenario, some balls were created and set at random positions on the ground level. An NXT robot was added to the scene. The robot is to be programmed to move to the positions of the balls one after the other, grab the balls, and drop the balls into a pit.
Illustration of the scenario:

  1. The NXT robot moves in the direction of the blue ball
    2. The NXT robot approaches the blue ball

  2. The robot grabs the blue ball
    3. The NXT robot grabs the blue ball

  3. The robot moves to drop the blue ball in the pit
    4. The NXT robot drops the blue ball in the pit

  4. The robot repeats the grabbing and dropping action until all the balls are finally dropped in the pit
    5. All the balls are dropped in the pit
