I have recently developed a multi-wheel differential drive plugin compatible with ROS Melodic. It solves the drawback of inbuilt differential drive plugin which only supports two wheels. Here is the link to the repository: Multi-wheel differential drive. I would appreciate any feedback or recommendations for improvements. Hope you guys enjoy it.
Neat initiative but isn’t it done by the diff_drive already? There is a skid steer option if you define a joint array in the diff drive config file:
jackal_velocity_controller: type: "diff_drive_controller/DiffDriveController" left_wheel: ['front_left_wheel', 'rear_left_wheel'] right_wheel: ['front_right_wheel', 'rear_right_wheel'] ...
I’ve taken the above from: http://wiki.ros.org/diff_drive_controller.
Do you do anything differently?
As for feedback, after a quick glance:
- It’s cool that you added a readme! Much appreciated!
- You could add .vscode directory to .gitignore
- Regarding git. I highly recommend this article: https://chris.beams.io/posts/git-commit/ if you use this advice your repo will look more professional straight away.
Sorry for the delay. I was expecting this question. This package is developed as an improvement to the in-built differential drive ROS Gazebo plugin and has all its features.
Yes, it is different from the differential drive controller. This package has additional configurable parameters like;
1). Wheel Torque.
2). Togglable Odom, tf and joint state publishers.
Furthermore, Skid steer plugin supports only four-wheeled robots, whereas this plugin support 2N wheeled robots, where N is a natural number.
Thanks for the feedback, I will incorporate them into my projects.
