I highly recommend the Rotational Sensor to all of you robot builders!
I bought two, and it's been a blast!

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

The second thing I built was a "new" (I've never seen this done before)
steering mechanism.
I wish I have a digital camera, this explanation would have been much
clearer with a picture.
But here it goes anyway...
Basically, I use a string ( Non-LEGO, sorry... but I need a rather long
string) to steer the vehicle remotely.
It's kinda like guiding a dog with a leash.  You hold the trailing string
behind the vehicle.
You control the vehicle by moving the string left, right, or straight behind
the vehicle.
Of course, a rotational sensor was used to detect the angle of the string.
I also hooked the end of the string (one on the vehicle) such that when I
tug the string it would toggle the motor power.  One tug, motors on, another
tug motors off.

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 (...)
