Thus, to test the power of OGR or tropotaxis as explanations of plume tracking by lobsters, we constrained the following critical features to known lobster values: body size and shape, sensor arrangement in space, speed and pattern of locomotion, and temporal and spatial resolution of the sensors in the robots' hardware and software to known lobster values (Grasso et al., 2000).
Probable strategy: odor-conditioned taxis and tropotaxis. Representative animal: lobsters, blue crabs.
forbesi is performing a tropotaxis by comparing different concentrations at the tips of its arms, we would expect to find some initial directional decisions towards the odor source and decreased heading angles as the animal approached the source.
