This week we had our design review and continued work on our navigation system. Our robot’s navigation is controlled using the navigation stack from ROS (Robot Operating System). It is a serious of open-source Python and C++ codes that are maintained and endorsed by ROS. We are using a global map and monte carlo localization from our laser scanner along with set location points to plan paths between our goals. Each “node”, or script, serves an important function to the success of the system and includes dozens of parameters unique to the robot. We have spent the majority of this week setting these parameters for the navigation.
