flow constant. Some examples: They measure the distance they have travelled. This is important as distance is signalled to other bees as a component of the waggle dance. When landing, the ground becomes closer and therefore appears to be moving faster. By keeping the apparent velocity of the ground constant, the bee reduces its own velocity in a continuous manner. Similarly, bees slow down in a crowded landscape because nearby objects appear to move faster than objects on the horizon. This is a safety mechanism that reduces the incidence of collision. When avoiding objects, the bee will tend to take the optimal path because it will 'balance' the rate of the optic flow between the eyes. It will, for example, fly down the middle of a tunnel, because if it flew closer to one side the optic flow would appear to be greater. Srinivasan's research looks mainly at "vision, perception and cognition in animals with simple nervous systems, and on how these might be used in machine vision and robotics". Awards and honours Srinivasan's work has been recognised and honoured by a number of awards and honours, including: 1995 - Election to the Fellowship of the Australian Academy of Science (FAA) 2001 - Inaugural Australian Federation Fellowship award of the Australian Research Council 2001 - Australasian Science Prize (for excellence in peer-reviewed research) 2001 - Election to the Fellowship of the Royal Society of London (FRS) 2003 - Australian Centenary Medal 2006 - Royal Society of New Zealand Distinguished Visitor 2006 - Fellowship of the Academy of Sciences for the Developing World 2008 - Queensland Smart State Premier's Fellowship 2008 - Rank Prize for Optoelectronics (UK) 2009 - Distinguished Alumni Award of the Indian Institute of Science 2012 - Membership of the Order of Australia (AM) Publications , Srinivasan had authored 15 book chapters, 189 journal articles, 69 conference papers, and had registered two patents. The patents were registered with co-authors Javaan Singh Chahl and other researchers: a "novel system for panoramic video surveillance" in 1997, and an imaging system in 2002 (US).
