Detailed Description

Interface for Pioneer mobile robots based on Aria 3rd party library.

This class provides a position and speed control interface for Pioneer mobile robots. It inherits from the Aria ArRobot class. For more information about the model of the robot, see vpPioneer documentation.

Examples:: movePioneer.cpp, servoPioneerPanSegment3D.cpp, servoPioneerPoint2DDepth.cpp, servoPioneerPoint2DDepthWithoutVpServo.cpp, sonarPioneerReader.cpp, and tutorial-pioneer-robot.cpp.

enum vpRobot::vpControlFrameType

inherited

Robot control frames.

Enumerator
REFERENCE_FRAME	Corresponds to a fixed reference frame attached to the robot structure.
ARTICULAR_FRAME	Corresponds to the joint state. This value is deprecated. You should rather use vpRobot::JOINT_STATE.
JOINT_STATE	Corresponds to the joint state.

void vpRobotPioneer::setVelocity	(	const vpRobot::vpControlFrameType	frame,
		const vpColVector &	vel
	)

virtual

Set the velocity (frame has to be specified) that will be applied to the robot.

Parameters

frame : Control frame. For the moment, only vpRobot::ARTICULAR_FRAME to control left and right wheel velocities and vpRobot::REFERENCE_FRAME to control translational and rotational velocities are implemented.

vel

: A two dimension vector that corresponds to the velocities to apply to the robot.

If the frame is vpRobot::ARTICULAR_FRAME, first value is the velocity of the left wheel and second value is the velocity of the right wheel in m/s. In that case sets the velocity of the wheels independently.
If the frame is vpRobot::REFERENCE_FRAME, first value is the translation velocity in m/s. Second value is the rotational velocity in rad/s along the vertical axis.

Note that to secure the usage of the robot, velocities are saturated to the maximum allowed which can be obtained by getMaxTranslationVelocity() and getMaxRotationVelocity(). To change the default values, use setMaxTranslationVelocity() and setMaxRotationVelocity().

Exceptions

vpRobotException::dimensionError	: Velocity vector is not a 2 dimension vector.
vpRobotException::wrongStateError	: If the specified control frame is not supported.
