Robotino® communication

Main functionalities

The main functionality of the module is to communicate with the Robotino® . The Robotino® is a mobile robot platform for research and education developed by Robotics Equipment Corporation GmbH and distributed by Festo Didactic.
In case this module is in operation, i.e., the robot control software for the use case demonstration is operated by the end-user, then the end-user cannot perform any modification on this module since this module is part of the robot control software. In case this module is included in another robot control software (developed by third-party SME), then a software developer can implement algorithms for communication with the Robotino® using this module.
The typical application scenario for this module is to implement communication algorithms with Robotino®.
The demonstration is available both for internal and for external use.

Technical specifications

This module is an adaptation of the qDSA protocol of the API1 for Robotino® v2 , made in native VIs for use with LabVIEW™ software without the need to call external code.
Hardware requirements of the module: Festo Robotino® v2 (Firmware 670, OS Date: 11.02.2011), Wi-Fi access point (AP) (factory standard accessory), UVC standard Webcam (factory standard accessory).

The module consists of two continuously running parallel loops (tasks). One task is dedicated to the keep-alive type communication of the Robotino®, where the Robotino® continuously sends data to the host computer and expects data in response. The other task is the receiver of the camera images, continuously sent by the Robotino® if the camera is enabled.
The module is already available in source code and as a part of a standalone desktop application by contacting the authors of this description.
