[ros-users] [Discourse.ros.org] [TurtleBot] Teleop_twist_joy - Inconvenient button settings

[Tully Foote]

The design of the TurtleBot controls is that if you want to stop the robot you can just let go and it will stop if it does not continue to receive commands driving forward. 

Can you explain what you mean by having different keys to move and turn? Usually driving the TurtleBot is done by holding the deadman and then the analog joystick controls forward speed and turn rate.

When you let go of the deadman switch the vehicle stops itself based on a timeout. if you release the joystick, keeping the deadman pressed,  it springs back to center and the vehicle also stops gently.

If your joystick has different axes/button orders you may need to set parameters to adjust for your joystick's mapping.  The parameters for teleop_twist_joy are documented here: http://wiki.ros.org/teleop_twist_joy

See http://learn.turtlebot.com/2015/02/01/9/ and http://wiki.ros.org/turtlebot_teleop/Tutorials/indigo/Joystick%20Teleop for examples of tuning instructions. 

At OSRF we mostly test with the F710 wireless Gampad: http://gaming.logitech.com/en-us/product/f710-wireless-gamepad.
