Hardware Requirements

This package uses a joystick or keyboard for teleoperation of Care-O-bot. To use this package you need either a real Care-O-bot or a simulated one (see cob_gazebo).

ROS API

The cob_teleop package provides both, a configurable node for teleoperation by joystick or by keyboard.

cob_teleop

The cob_teleop node takes in sensor_msgs/Joy messages and send direct commands to the hardware.

Subscribed Topics

Usage/Examples

Starting teleoperation node

For starting the teleoperation with joystick

roslaunch cob_bringup teleop.launch

For including the teleoperation in your overall launch file use

<include file="$(find cob_bringup)/tools/teleop.launch" />

If you haven't got joystick you can move the base of the robot using the keyboard:

roslaunch cob_teleop teleop_keyboard.launch

Move components

To be able to use the joystick the deadman_button has to be pressed all the time, as soon as the button is released a stop will be send to all hardware components. Have a look at the following image to see which buttons command which components. teleop.png

For moving the base: Hold the deadman button and use the base rotation and translation axis to move the base.

For moving the torso: Hold the deadman button and the upper or lower neck button, then use the up_down or left_right axis to move the torso.

For moving the tray: Hold the deadman button and the tray button, then use the up_down axis to move the tray.

For moving the arm: Hold the deadman button and one of the arm buttons, then use the up_down or left_right axis to move the selected arm joints.
