I developed K-9 from inspiration as being a robot companion and mature toy. K-9 is interactive but he shines as an independent personality. He is aware of his surroundings which gives him the ability to move around your enviroment. His personality changes as would a real pet, but he won't just turn himself off when you turn your back. Instead, he'll go off and explore. His autonomous awareness prevents him from fallin down stairs, driving into things or requiring your assistance.
