Children with developmental disorders often exhibit reduced motivation and passiveness in their playing behaviour, impacting their engagement in motor rehabilitation tasks. Robot-assisted therapy combined with virtual/augmented reality can enhance involvement and treatment outcomes. This paper discusses the initial steps in integrating a telepresence system into a rehabilitation platform for children with Cerebral Palsy. Two experiments were performed to validate the platform. The first one tested the navigation capability of the mobile robot, showing an average mapping accuracy of 0.13 m. The second experiment demonstrated synchronization between the treadmill and the mobile robot, to demonstrate the feasibility of telepresence functionalities. Future work involves further testing, system synchronization improvements, and adding image transmission from the mobile robot to the VR headset.
