Question

The following situation uses a robot in a grid of squares. The robot is represented by a triangle which is initially in the top right square and facing left. The robot may not travel through the black squares. Create a solution that would enable the robot to be in the position found below using at least 2 loops. (This is the end result with the arrow being in the second row from the bottom.)

Answer 1

The solution involves programming two loops to move a triangle-shaped robot: one loop to reach the leftmost column, another to reach the second row from the bottom, avoiding black squares.

Step-by-step explanation:

To achieve the goal of moving a robot to a specific position on a grid using at least 2 loops, one could use a programming approach such as creating a loop for moving the robot left until it reaches the leftmost column, and then using another loop to move the robot down to the second row from the bottom. The provided figures and steps related to displacement vectors and two-dimensional motion are helpful for visualizing grid-based movement, which can be adapted into programmatic instructions for the robot.

Consider the following pseudocode as an example:

• While robot is not in the leftmost column: move left
• While robot is not in the second row from the bottom: move down

The specifics of the grid and the black squares would determine the condition checks within each loop to avoid obstacles.
