Question

The figure below uses a robot in a grid of squares. The robot is represented as a triangle, which is initially in the bottom white square and facing up. The goal is to move the triangle to the gray square. What are the steps to achieve this goal?

1) Move forward and rotate right
2) Move backward and rotate left
3) Move left and rotate right
4) Move right and rotate left

Answer 1

To move the triangle from the starting square to the goal square in the grid, you need to follow the given steps: Move forward and rotate right, move backward and rotate left, move left and rotate right, move right and rotate left.

Step-by-step explanation:

To move the triangle from the bottom white square to the gray square, you need to follow the steps:

1. Move forward and rotate right: Move the triangle one square forward and then rotate it 90 degrees to the right.
2. Move backward and rotate left: Move the triangle one square backward and then rotate it 90 degrees to the left.
3. Move left and rotate right: Move the triangle one square to the left and then rotate it 90 degrees to the right.
4. Move right and rotate left: Move the triangle one square to the right and then rotate it 90 degrees to the left.
