Research interests

Focusing his attention on bees, Srinivasan has explored how simple animal systems display complex behaviours. This broad field has applications in robotics, especially unmanned aerial vehicles because of the competing needs for autonomy and a lightweight control system.

Bees are highly competent fliers. Srinivasan has shown that many ostensibly complex flight behaviours can be attributed to the tendency of the bee to keep optic 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
    Waggle dance
    Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share with their hive mates information about the direction and distance to patches of flowers yielding nectar and pollen, to water...

    .
  • 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.
