In addition to this I followed the readme file to build the pi_sonar as shown:
Sonar Sensor Handling based on
git clone https://github.com/UbiquityRobotics/pi_sonar.git
The node needs to access the pigpio daemon, hence the following steps to have it run at startup (if it does not do so already):
sudo cp pigpiod.service /etc/systemd/system
sudo systemctl enable pigpiod.service
sudo systemctl start pigpiod.service ******(THIS LINE)******
And encountered the following error:
Job for pigpiod.service failed because the control process exited with error code. See “systemctl status pigpiod.service” and “journalctl -xe” for details.
After looking at “systemctl status pigpiod.service” i got the following:
~/catkin_ws$ systemctl status pigpiod.service

Im not sure if this is the cause of my issue. Also I am unsure whether this must be executed in the catkin_ws or not.
