early concept type stuff

tough-nut is a shop-bought tin robot.
he thinks he's tough, but really he's a big nancy!

knitwit is a rag-doll robot
when he isn't "alive" he is totally floppy
when he is, he will be far more sturdy and human (i may opt for hosepipe animation on his arms)
this whole design is open to change, but not the concept
