a$)$ The first system that you will test is the navigation system. The robot maps the territory by calculating

distances and angles whilst moving between various locations. It then stores on its system the shortest

direct path from initial location to the intended target. During the test the robot navigates around a

muddy surface in the following path: $55$cm $[$NW$]$ and then moves $45$cm $[$S$30$W$].$ The robot sends back

to the server the following overall shortest path: $70$cm $[$W$10$

oS$].$ Use triangle or parallelogram method to

verify the precision of the robot$$s navigation

system.
