LIDAR

Follow along: LIDAR Sensor Operation Example

The program launching process along with parameter settings are all simplified and set up on the Jupyter Notebook Environment.

Open the 01_04_scan.ipynb Jupyter Notebook
Import the necessary python libraries and modules
Follow and Execute the example codes

(The Jetson Board used for these examples are => Jetson Nano)

Open the following jupyter notebook:

03_04_scan.ipynb
To run the cells within the notebook use Ctrl + Enter

Import the necessary python libraries and modules

import rospy
from sensor_msgs.msg import LaserScan

Create zetabot Node
Subscribe to the “scan” topic, and display the published information.

def process_scan(msg):
    rospy.loginfo("data: {}".format(msg))

def start_node():
    rospy.init_node('zetabot')
    rospy.Subscriber("scan", LaserScan, process_scan)
    rospy.spin()

try:
    start_node()
except rospy.ROSInterruptException as err:
    print(err)
