Ghengis is a very classy walker created by Rodney Brooks of i Robot.

It has six legs, and uses Subsumption Architecture.

It has an array of heat sensors, and is built up with behavioural layers from a basic instruction top stand, through to walking(lifting a foot, and following with an involuntary step reflew), through to a complex hunt and prowl behaviour.

Ghengis sensing behavioru is based on movement. When it senses movement, it will turn towards it, and walk towards the stimulus.
