player_position2d_velocity_mode_config Struct Reference
Detailed DescriptionRequest/reply: Change velocity control.
Some robots offer different velocity control modes. It can be changed by sending a PLAYER_POSITION2D_REQ_VELOCITY_MODE request with the format given below, including the appropriate mode. No matter which mode is used, the external client interface to the
position device remains the same. Null response.
The p2os driver offers two modes of velocity control: separate translational and rotational control and direct wheel control. When in the separate mode, the robot's microcontroller internally computes left and right wheel velocities based on the currently commanded translational and rotational velocities and then attenuates these values to match a nice predefined acceleration profile. When in the direct mode, the microcontroller simply passes on the current left and right wheel velocities. Essentially, the separate mode offers smoother but slower (lower acceleration) control, and the direct mode offers faster but jerkier (higher acceleration) control. Player's default is to use the direct mode. Set mode to zero for direct control and non-zero for separate control.
For the reb driver, 0 is direct velocity control, 1 is for velocity-based heading PD controller.
