In the process of researching the crosstalk problem in wireless infrared communication, Victor Kuo developed a proof-of-concept system for robotic modules that relies on antenna diversity. Antenna diversity is an existing technology that allowed Kuo to use multiple antennas attached to one radio. So, Kuo's system can can handle many transmitters sending at the same time. Previously, crosstalk was a major obstacle in robotics using radios for module to module communication.
In robotics, the ability to downscale is also a concern. Kuo's system solves that problem by using magnetic induction in a near-field communication situation. At that scale, the signal to interference ratio would be even better than in the wide-area infrared communication.
Parallel wireless radio communication architecture will be a very powerful tool as this method can also could be used to communicate when the modules are connected, allowing it to be employed in wide-area, near-field and direct-connect situations. Kuo's future plans include methods to make the communications model more robust, and to develop custom modules of his own.
Victor Kuo is currently a PhD student in robotics from the Australian Centre of Field Robotics, University of Sydney and is a student member of the IEEE. He received a B.E (Hons) in Mechatronics Engineering and B.Sc in Computer Science from the University of Sydney, Australia. His research interests include cellular and modular robotics, distributed robotics and wireless communication architectures.
