Hi all.

I'd like to translate /cmd_vel(geometry_msgs::Twist) to ackermann_msgs::ackermannDrive.

Linear speed is same in two msgs.(linear.x = speed)

How can I covert angular velocity to steering angle?(angular.z --> steering_angle)

Are there nodes for it? I couldn't find to translate from angular velocity to steering angle.

Could you please let me know equation and necessary parameters?

Thanks.

Not sure if you still need to know, but ...

Theta_dot would be angular.z and phi is steering angle
