Yes, I have a couple of them too and they give you so many possibilities...

I like this! My children would love a robotic pet to guide with a leash. I
might enhance your system and detect the strenght applied to the leash to make
the "pet" stop or run. Or better, a second rotation sensor to detect the slope
of the leash: eg under 45° means "go" and over 45° means "stop". I'm going to
work on it in the next days. Thanks for the idea

| First, I'd like to thank Hao-yang Wang for letting all of us know about the availability of rotational sensors. In case you missed it: >I saw both the rotation sensor (9756) and the temperature sensor (9755) at >www.legoworldshop.com last week. >( I (...)
