A simple robotic spider toy that hangs on
a chain (with its counterweight resting
area) but when it senses a change in the
lighting like an approaching friend, it
runs
up the chain to your shoulder where it is
safe.
More specifically, it climbs up your body
but counts the links on
the chain. A
passing shadow will only make it run up
to
the level of 5 links and then set back
to starting postition, whereas a
completely
darkend room will make it climb your
shoulder and stay there for a while. A
simple internal mercury switch could tell
it
that it has reached your shoulder.

didn't people used to wear chained insects at one time? |
|
| |
But what if you're arachnophobic? Can you make some sort of mammalian alternative? Like a squirrel or something? |
|
| |
Yes, Po, many people still do. |
|

//mammalian alternative?// |

That would be somewhere in the
product line. I suggested 8 legs
because they are rather elegant and
spiders look good with jems if one
wanted to go that route also. |

its a dead creepy day at hb today. |
|
| |
if it bit my neck, it would scare me even more. |
|
| |
"Is this thing bugging you ma'am?" |
|
| |
Too big a bug and the chain would just rotate. |
|
| |
too long a chain and it might throttle you. |
|
| |
That's ultimately why I settled for the
mercury switch. The first robots from
the 60's could follow a line without
having to touch it. The mercury switch
could tell it that it reached the proper
height, also considered a pendant as a
resting place for the robot that would
also act as a counterweight. |

Could you remove the reference to RFID? You're treating it like a magic mutual detection mechanism, and that just doesn't work. It's a nice idea otherwise. |
|
| |
I deleted it, it wasn't really important to
the idea. I figured that some company
that may make this would work it out in
such a way so that their products aren't
afraid of each other. |

What if someone was stood over your shoulder? |
|
| |
With its two front legs up in the air it
would hiss at you. |
|
| |
<Which leads me to the obvious> What if two people were simultaneously looking over each shoulder? (I'm imagining two men looking over a large breasted females shoulders, to get a good view). |
|
| |
She'd probably belt both you and your
friend but it
would be up to
the personal preference of said
theoretical female. :) |
|
| |
If it could be a fire breathing dragon or a venom spitting cobra... that could be interesting. ;) |
