In previous papers 1] we have argued that the LAAS architecture 1 is one of the most suited for mobile robot control. This statement may seem over-optimistic, not to say pretentious and unveriiable.

Adult cane toads, B. marinus, survived in salinities up to 40% sea-water (SW). Pre-exposure to 30, then 40% SW, increased the survival time of toads in 50% SW. Plasma from toads acclimated to salt water is hyperosmotic to the environment--a result of increased plasma sodium, chloride and urea concentrations. When toads were placed in tap-water and 20% SW, all significant changes to plasma sodiu...
