Detailed Description
A robot that moves in 3-D.
The position3d interface is used to control mobile robot bases in 3D (i.e., pitch and roll are important).
Typedef Documentation
typedef struct player_position3d_cmd_pos player_position3d_cmd_pos_t |
Command: position (PLAYER_POSITION3D_CMD_SET_POS)
It accepts new positions and/or velocities for the robot's motors (drivers may support position control, speed control, or both).
typedef struct player_position3d_cmd_vel player_position3d_cmd_vel_t |
Command: velocity (PLAYER_POSITION3D_CMD_SET_VEL)
It accepts new positions and/or velocities for the robot's motors (drivers may support position control, speed control, or both).
typedef struct player_position3d_data player_position3d_data_t |
Data: state (PLAYER_POSITION3D_DATA_STATE)
This interface returns data regarding the odometric pose and velocity of the robot, as well as motor stall information.
typedef struct player_position3d_geom player_position3d_geom_t |
Request/reply: Query geometry.
To request robot geometry, send a null PLAYER_POSITION3D_GET_GEOM request.
Request/reply: Change position control.
To change control mode, send a PLAYER_POSITION3D_POSITION_MODE request. Null response.
Request/reply: Set position PID parameters.
To set position PID parameters, send a PLAYER_POSITION3D_POSITION_PID request. Null response.
typedef struct player_position3d_power_config player_position3d_power_config_t |
Request/reply: Motor power.
On some robots, the motor power can be turned on and off from software. To do so, send a PLAYER_POSITION3D_REQ_MOTOR_POWER request with the format given below, and with the appropriate state
(zero for motors off and non-zero for motors on). Null response.
Be VERY careful with this command! You are very likely to start the robot running across the room at high speed with the battery charger still attached.
typedef struct player_position3d_set_odom_req player_position3d_set_odom_req_t |
Request/reply: Set odometry.
To set the robot's odometry to a particular state, send a PLAYER_POSITION3D_SET_ODOM request. Null response.
typedef struct player_position3d_speed_pid_req player_position3d_speed_pid_req_t |
Request/reply: Reset odometry.
To reset the robot's odometry to , send a PLAYER_POSITION3D_RESET_ODOM request. Null response. Request/reply: Set velocity PID parameters.
To set velocity PID parameters, send a PLAYER_POSITION3D_SPEED_PID request. Null response.
Request/reply: Set speed profile parameters.
To set speed profile parameters, send a PLAYER_POSITION3D_SPEED_PROF request. Null response.
Request/reply: Change velocity control.
Some robots offer different velocity control modes. It can be changed by sending a PLAYER_POSITION3D_VELOCITY_MODE request with the format given below, including the appropriate mode. No matter which mode is used, the external client interface to the position3d
device remains the same. Null response.
