You can watch videos of TIAGo in action through the following YouTube TIAGo Playlist. In there you will find our mobile manipulator robot used for many research projects, robotics competitions or showing specific features. Enjoy!

The different motors of the mobile manipulator robot can be controlled using ROS interfaces. All the controllers provided are implemented as plugins of ros_control and are contained in ros_controllers. All the controllers run in the real-time control loop and have access to the full robot hardware interfaces exposed by ros_control. The motors of TIAGo can be controlled in the following modes: The wheels of the mobile base can be controlled through velocity mode. The motor of the lifting torso and the two motors of the head can be controlled in position mode. Finally, the motors of the arm can be controlled in position and in effort mode.

Yes. The user only needs to create ros_control plugins to implement new controllers and add them to the ros_controllers or replace the desired ones. The new controllers will run in the real-time control loop and will have access to the full mobile manipulator robot hardware interfaces exposed by ros_control.

Yes. Compliance in TIAGo’s arm is achieved by using two mechanisms: Sensorless torque control: open-loop torque references are commanded. This is based on feedforward current control which is achieved thanks to the accurate model of the arm dynamics including mechanics, electronics cabling and covers and the low friction of the joints. This results in a high acceptable force control in the operational space. Admittance control: using the data from the force/torque sensor of the wrist, positions can be commanded taking external forces into account obtaining even much better results than when using sensorless torque control.

Yes. They use the same mounting connector and the same interface on the mobile manipulator robot. The process for interchanging the end effectors in TIAGo is very easy and fast.

The mobile manipulator robot has 1 year warranty on hardware. The warranty for your TIAGo can be extended according to your need.
