Four legged robot URDF in Rviz and Gazebo Video

How to run

• Clone the repo git clone https:/mohamedsayed18/Robot_Dog.git
  
• Put the packages (spot, rrbot_control) in your work space
  
• build the work space catkin_make
  
• then write this command
  Run all from one launch

Or run them separately
launch the robot in gazebo
roslaunch spot dog_world.launch
launch the control files

Control in Gazebo

i followed this tutorial
this repo contain examples which they use in the above tutorial

3- build the urdf file
4- improve my urdf with xacro
5- launch on gazebo

draft

• Do work in a separate branch, make pull request (PR) and put link to PR in the moodle. Let’s agreed to merge PR only after my review-grading.
• Add a camera sensor to one of your movable link.
• Implement a publisher that moves the link with a camera
• Implement a subscriber that saves images from a camera to files (the name should increment like pic1.png pic2.png etc).
• Add launch file to run all needed nodes.
• Make small video showing that all is working, not more than 20 sec.
