Sensory motor skills (also known as sensorimotor skills) are those we use to take in information about the world through our senses and to develop our body's movement, or motor, response to that information

Bathtub Motor 

A poorly engineered thing; particularly one that is over-complicated, with excess and unnecessary parts. The term comes from a Heinlein quote/novel.

"If one is building an electric motor, one uses only the parts needed to do so. You would not, for instance, add a bathtub simply because one was available."

"Why does this thing even have one of those?"
"It's a bathtub motor."

purr motor

When your cat makes a low-pitched rumbling sound that is (mostly) quiet but you can feel the kitty’s body vibrating

This has several evolutionary advantages:

1) the frequency at which cats purr promotes healing

2) kittens use this to get their mom to settle down and nurse

3) a rather high pitched purr (this evolved with domestication) can coax an owner into giving the cat an extra snack, or hairball gel.

Josh: Mittens has the loudest purr motor
Steve: I know. Bear’s purr motor got quiet as he grew up. Sometimes his purrs are really hard to ignore. But no matter how hard he purrs I still have to work.

. Adjective

That hot rod only ran a 13 sec pass at the track, it has a flat motor.
