Gregory, there is something you need to come to terms with.
They were not accidents :^)
What you really need is a robotic sister!
BTW, the old Robbie robot from radio shack (about 15 years back) had a ultrasonic remote, and a mode in which it would follow the remote - but if I remember right it did not stop when the remote stopped.
