joy_node how to publish to cmd_vel topic? [closed]
So, Ubuntu 20.04 with Noetic installed on robot. Have a motor driver working and can drive the bot with:
"rosrun teleop_twist_keyboard teleop_twist_keyboard.py cmd_vel=:/hoverboard_velocity_controller/cmd_vel"
Then installed joy_node, and tested input from game controller. (don't seem to have proportional values from joy sticks - a drama for later) but for now I just need it to publish to /hoverboard_velocity_controller/cmd_vel.
How do I do that?
