Note: before moving the robot base, you may want to tuck the arms out of the way.

Bring up the robot

As with all applications, you must first bring up your robot.

Joystick teleoperation

The PR2 is equipped with a Playstation3 (PS3) controller.

Pairing

Before use, the PS3 controller must be "paired" with the robot. If your controller is not already paired, you can pair it by pressing the center button, shown in the image. If you need to pair a new PS3 controller to the PR2 (i.e. not the controller that came with it), see the tutorials.

There is currently no feedback from the controller or the robot during or after pairing. The best way to tell if they have been paired correctly is to try issuing commands to the robot via the joystick as described below.

Launching

Launch joystick teleop:

roslaunch pr2_teleop teleop_joystick.launch

Now you should be able to control the robot's base and spine with its PS3 controller.

Controlling

Moving the Base

To drive the robot around (i.e., drive the base), hold down L1 and use the two joysticks to control its direction of movement (right joystick) and rotation (left joystick). To drive the robot around at faster speeds, also hold down R1.

Moving the Head

To move the robot head, hold down L1 and L2 and use the two joysticks to control the head movements.

Moving the Torso

To move the robot torso, hold down L1 and press the triangle button to move the torso up or the X button to move the torso down. The torso moves slowly.

Controller Buttons

Control is configured as follows:

Button

Control Action

L1

The "deadman" control allows the joystick to send commands to the robot; the robot will only respond to the joystick when this button is held down

L2

The "head" button allows the sticks to control the head instead of the base

Left stick

Rotate (yaw) the base

Right stick

Move (translate) the base

Triangle

Move the torso up

X

Move the torso down

R1

The "run" button commands the base to drive faster

Circle

Open right gripper

Square

Close right gripper

D-pad right

Open left gripper

D-pad left

Close left gripper

Note: The L1, L2, R1, and R2 buttons are all labeled on the controller.

Unpairing the Joystick

The joystick should unpair from the PR2 automatically after 15 minutes of inactivity, to save battery life. If you ever need to unpair the joystick explicitly, simply press the pairing button for 10 seconds, after which the joystick lights should stop blinking.

Keyboard teleoperation

The robot base can be controlled via keyboard commands.

Launching

Launch keyboard teleop:

roslaunch pr2_teleop teleop_keyboard.launch

Now you should be able to control the robot base with keyboard commands in the shell where you ran the above roslaunch command.

Control

The keys that you can use, and what they do, are displayed to the screen.
