ROS Software Maintainer: PAL Robotics

TIAGo OMNI Base is PAL Robotics’ recently developed omnidrive robot. TIAGo OMNI Base is complete with omnidirectional drive with 3 DoF mecanum wheels and includes two LIDAR sensors for an unobstructed 360º FOV secure movement. This includes autonomous navigation and obstacle detection. TIAGo OMNI Base is part of the TIAGo robot family, which includes the original Autonomous Mobile Robot (AMR) with differential drive, TIAGo Base.

TIAGo OMNI Base users can take full advantage of the manoeuvrability offered by TIAGo OMNI Base’s omnidrive base for path planning. The omnidirectional robot base provides precision positioning even in constrained environments. This is where a robot with omnidirectional movement appears to be the most optimal proposal thanks to its versatility of 360º movement.

In summary, TIAGo OMNI Base offers the following advantages:

It also has already developed software for navigation. This robot runs on ROS Melodic/Noetic internally, and uses state-of-the-art ros_control components.

Tutorials

A comprehensive set of tutorials are now available for the TIAGo OMNI Base robot in Robots/TIAGo-OMNI-base/Tutorials. The tutorials make use of the Gazebo simulator and currently contains tutorials on autonomous navigation. Comprehensive instructions on how to install the public simulator are provided.

Public simulation packages overview

This section presents an overview of the packages used in the public simulation of TIAGo OMNI Base, with links to the corresponding packages. For the installation instructions of the packages please refer to TIAGo OMNI Base simulation installation tutorial.

Control the robot

TIAGo OMNI Base supports a logitech joystick by default.

Controllers from other vendors may have different key mappings. In this case the joy_teleop.yaml file needs to be changed to reflect the different configuration.

If you had one plugged when you started up the (real or simulated) robot, now it can be used. Activate the joystick commands by pressing the 'X' button, and drive using the controllers. This activation behaviour comes in very handy when the robot is navigating autonomously but a rapid interruption is needed.

One can also use the rqt_robot_steering plugin to drive the robot by sending commands directly to /mobile_base_controller/cmd_vel
