Video: Snail robot climbs vertical walls without leaving a slimy trail

Snails are great at climbing vertical surfaces, even though they have just a single wet suction-cup foot. A new robot climbs walls by mimicking that simple yet effective mechanism, although thankfully it leaves a trail of water instead of mucus.

Energy-efficient underwater robot rises and falls via fuel-cell balloons

If scuba divers use inflatable BCDs (buoyancy control devices), why don't underwater robots? Well, an experimental new one does, and the technology is said to be much more energy-efficient than traditional methods of moving up and down in the water.
