car driving model about stage_ros HOT 1 OPEN

Nope. It is pure kinematic model that is used in libstage/stage_ros. You can control its velocity immediately.

In fact, there are three control modes in libstage:

typedef enum { CONTROL_ACCELERATION, CONTROL_VELOCITY, CONTROL_POSITION } ControlMode; 

• CONTROL_VELOCITY - you change robot state by setting it velocity directly (x, y, angular).
• CONTROL_ACCELERATION - you set acceleration, and velocity and position are updated accordingly
• CONTROL_POSITION - you change position of the robot directly.

stage_ros uses CONTROL_VELOCITY. You can use intermediate node, that recalculates from ackerman_msgs to appropriate sensor_msgs::Twist to make robot movement look exactly like ackemann's kinematics.
