Recent studies have suggested that physical rehabilitation performed with robotic devices can enhance arm movement recovery following stroke. In these studies, the robotic devices mechanically assisted arm movement as the patient attempted to move. Although this “robotic active assist” technique has shown promise, a key question remains unanswered: is the mechanical assistance provided by the r...

The rubber hand illusion is an experimental paradigm in which participants consider a fake hand to be part of their body. This paradigm has been used in many domains of psychology (i.e., research on pain, body ownership, agency) and is of clinical importance. The classic rubber hand paradigm nevertheless suffers from limitations, such as the absence of active motion or the reliance on approxima...

Hybrid robotic systems represent a novel research field, where functional electrical stimulation (FES) is combined with a robotic device for rehabilitation of motor impairment. Under this approach, the design of robust FES controllers still remains an open challenge. In this work, we aimed at developing a learning FES controller to assist in the performance of reaching movements in a simple hyb...

The E-CD++ tool uses the RT-DEVS (real-time DEVS) formalism for modeling, simulation and execution of realtime and embedded applications. This formal modelling and simulation approach can be used as a robust foundation for developing real-time and embedded applications. It eases verification of the product, as sometimes verifying an embedded application in the real environment can be very risky...

Rehabilitation robotics applications and their developments have been spreading out as consequences of the actual needs in the human activities of daily living (ADL). Exoskeletons for rehabilitation are one of them, whose intrinsic characteristics are quite useful for applications where repetitive, robustness and accurate performance are a must. As a part of robotic-mediatedrehabilitation progr...

In this paper, we present a directional antenna-based leader-follower robotic relay system capable of building end-toend communication in complicated and dynamically changing environments. The proposed system consists of multiple networked robots one is a mobile end node and the others are leaders or followers acting as radio relays. Every follower uses directional antennas to relay a communica...

To data, outside of the controlled environments, robots normally perform manipulation tasks operating with human. This pattern requires the robot operators with high technical skills training for varied teach-pendant operating system. Motion sensing technology, which enables human-machine interaction in a novel and natural interface using gestures, has crucially inspired us to adopt this user-f...

Radiofrequecy ablation is the most widely used local ablative therapy for both primary and metastatic liver tumours. However, it has limited application in the treatment of large tumours (tumours >3cm) and multicentric tumours. In recent years, many strategies have been developed to extend the application of radiofrequency ablation to large tumours. A promising approach is to take advantage of ...

Solenoids are important components of robotic drumming systems and several designs have been proposed. In this paper, we compare different designs in terms of speed and dynamic range and discuss the tradeoffs involved. The evaluation is performed in the context of MahaDeviBot, a custom built 12-armed MIDI controlled mechanical device that performs a variety of Indian folk instruments, including...

This study presents results from a randomized controlled clinical trial of the Mirror Image Movement Enabler (MIME) robotic device for shoulder and elbow neurorehabilitation in subacute stroke patients, including data on the use of its bilateral training mode. MIME incorporates a PUMA 560 robot (Staubli Unimation Inc, Duncan, South Carolina) that applies forces to the paretic limb during unilat...
