Rescue bot unit CH-LE. Nickname Charlie. Deployed to disaster areas for search and rescue. Main body compartment is a sophisticated cryogenic mobile medical unit that can fit up 2 adult males. Feet are designed for speed and agility over uneven surfaces and can leap distances of up to 100 metres. CH-LE units can walk on water by "expansion skating". Using a synthetic paste similar to mucus, the CH-LE will "spit" the paste onto the surface of the water and jump or "skate" across. Charlies like to collect unusual shaped rocks and debris in their spare time.
