d) One exploratory mapping session for a 1m by 1m can last 5 minutes. The new mapping system should be able to handle absolute coordinates in space as well. That is the compass directions might not be available. 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). Describe the trajectory of the move using the equation of line between the starting and the final location of the robot. Diagram for illustration purposes only
