Middle-scale navigation: the insect case
What is the large-scale spatial representation that insect foragers such as bees and ants form of their wider nest environs? This is the principal question which the following contributions aim to answer.
متن کاملMiddle Scale Robot Navigation -a Case Study
In this paper we present results of experiments carried out with a route learning system for a mobile robot, conducted in a `real world' environment covering distances of several hundred metres. The system uses no odometry and is based on a self-organising mapbuilding process using perceptual landmarks. A performance metric is deened and used to measure the robot's ability to traverse the route.
متن کاملSpatial Memory in Insect Navigation
A wide variety of insects use spatial memories in behaviours like holding a position in air or flowing water, in returning to a place of safety, and in foraging. The Hymenoptera, in particular, have evolved life-histories requiring reliable spatial memories to support the task of provisioning their young. Behavioural experiments, primarily on social bees and ants, reveal the mechanisms by which...
متن کاملNeural mechanisms of insect navigation.
We know more about the ethology of insect navigation than the neural substrates. Few studies have shown direct effects of brain manipulation on navigational behaviour; or measure brain responses that clearly relate to the animal's current location or spatial target, independently of specific sensory cues. This is partly due to the methodological problems of obtaining neural data in a naturally ...
متن کاملMotion detection in insect orientation and navigation
The visual systems of insects are exquisitely sensitive to motion. Over the past 40 years or so, motion processing in insects has been studied and characterised primarily through the optomotor response. This response, which is a turning response evoked by the apparent movement of the visual environment, serves to stabilise the insect's orientation with respect to the environment. Research over ...
