One exploratory mapping session for a 1m by 1m can last 5 minutes. This new mapping system should be able to handle absolute coordinates in space, but the compass directions might not be available. Given: This mapping system uses cartesian system using as origin (0,0,0) the landing site. The robot starts the exploration at the point (1, 2, -3) and ends the exploration at the point (2, 0, 1). Find: Describe the trajectory of the move using the equation of line between the starting and the final location of the robot.
