Hi, First of all, I'm a newbie in this field. I want to control a differential drive robot(polaris2dx), basically, I need to move the robot to a specific location with a given pose. How can I apply different velocities to each link/joint(so as to apply different velocities to each wheel). Can anyone provide me an example plugin for this. Thanks in advance.
Gazebo ships with a DiffDrivePlugin example. Unfortunately, it isn't very well documented. But it is used in the pioneer2dx model, so you can try it out and then adapt it to your needs. You can test using it like this:
Open Gazebo and insert the pioneer2dx from the left panel's insert tab. The model loads the plugin, which will listen to pose messages on topic ~/pioneer2dx/vel_cmd.
To test sending commands, you'll need a publisher. You can modify the stand-alone publisher example by changing the topic to ~/pioneer2dx/vel_cmd and the pose to whatever you want.
It worked. Thank you. Actually I need to control each wheel separately. How can I do that? Is there any need to include the subscriber/publisher in a plugin to do this task?
