git clone https://github.com/yourusername/object_follower_bot.git

2. Build the package:

cd object_follower_bot
catkin_make

Usage

1. Launch the Gazebo simulator with the provided world and robot model:

roslaunch object_follower_bot gazebo.launch

2. Run the object follower node:

rosrun object_follower_bot follow_bot.py

Description

The follow_bot.py script subscribes to the RGB camera topic to detect objects. It calculates the error between the center of the detected object and the center of the camera frame. Based on this error, it controls the robot's movement to follow the object.

ROS Nodes

• Subscribes to: /camera/rgb/image_raw
• Publishes to: /cmd_vel

Launch Files
