Great! So we have three steps and need three blocks. These steps are:
- Move the robot forward
- Steer the robot to face the opposite direction (it needs to make a half circle)
- Move the robot back to where it started
Now that the robot is facing the other direction, does the robot go forwards or backwards to get back to where it started? Think carefully, and feel free to move the robot with your hands so you can picture what it needs to do.
