Navigation testing

Hey readers, welcome back to another progress update of our project! We hope to be giving you a weekly update of our project and share with you our

thoughts and feelings every week, such as this week's update.

This week we tested the navigation of the robot. We spent the 1st few days of the week troubleshooting why out robot cannot navigate properly, for example it will spin on the spot instead of going to the location and frequently the robot will be lost.

We found out the problem was in the roboclaw node we program. This node is in charge of controlling the robot speed and reading the encoder value for the robot's odometry. There was a variable called QPPS which stands for quadrature pulses per second, which means the fastest speed a motor can move in a second. Unfortunately we set the QPPS too low and therefore caused problems when we wanted to move the motor faster. After increasing the QPPS value we were able to make the robot navigate.
