This project was done using ROS Noetic on Ubuntu.
Clone the repository inside the src folder of your catkin_ws (source folder of your catkin workspace).
The repo can be cloned using the following commands in the terminal.
cd ~/catkin_ws/src
git clone /~https://github.com/DeepthiSudharsan/waiterbot.git
You can also download the zip file and extract it in the source folder.
Then, we do catkin_make
cd ~/catkin_ws
catkin_make
To run the robot model, run the commands given below
. devel/setup.bash
roslaunch waiterbot display.launch
Voila, you get the waiterbot in your rviz window along with a pop-up gui for controlling the robot movement!
