introduction

A robot navigating through a supermarket will not only have to avoid collision but also choose a route to their destination. The obvious choice is of course to always take the shortest path, however a supermarket will typically have multiple paths of the same length because of their grid-like layout and distance should not be the only factor we take into account when choosing a path, for example we might want to avoid dense groups of people. This research looks at the theoretical options for choosing a path and compares them.

relevant requirments

The main requirements we are taking into consideration here are:

1. Customers should feel safe

2. Robots should not get in the way

These requirements are respected by trying to avoid situations that are difficult to navigate through, minimizing situations where the robot has to move erratically or get too close to people to avoid them.
