Sample Code Snippet: Sensor Fusion in ROS

import rospy
from sensor_msgs.msg import Imu, LaserScan
from std_msgs.msg import Float32

def sensor_callback(imu_data, laser_data):
    # Process IMU and Laser data
    fused_data = process_data(imu_data, laser_data)
    rospy.loginfo(f"Fused Data: {fused_data}")
    pub.publish(fused_data)

def process_data(imu_data, laser_data):
    # Implement sensor fusion logic
    # Example: Combining orientation from IMU with distance from LIDAR
    orientation = imu_data.orientation
    distance = min(laser_data.ranges)
    return orientation.roll, orientation.pitch, distance

if __name__ == '__main__':
    rospy.init_node('sensor_fusion_node')
    pub = rospy.Publisher('fused_data', Float32, queue_size=10)
    rospy.Subscriber('imu', Imu, sensor_callback)
    rospy.Subscriber('laser', LaserScan, sensor_callback)
    rospy.spin()

This code snippet demonstrates how to fuse data from an IMU and a LIDAR sensor in a ROS-based autonomous system to improve environmental understanding.
