photovore

Arduino servo

Hi

I tried to build a photovore using and arduino and tested it via usb cable,so far so good the system worked as intended as soon as i plug my battery via the dc connector the servo worked but extremly slow why?

Seeks light, runs away when it bumps into something.

My first robot..........

So I've decided to build my first robot which not the LMR "start here" one (that one is going to be my second one) and im using this circuit- http://costaricabeam.solarbotics.net/Circuits/Vores/555%20Photovore.png . I've tried about 10 different designs for the body but its just not working. When i cover the left photocell with my hand and the other one is exposed to light the speed of the motors is the same and same with the right photocell. has anyone tried the circuit? did it work?

Run away robot

I don't have a enough skill to do it, yet, but it would be cool for one of you to make a robot that runs away and hides.  I was thinking you could make it go to the darkest part of the room and wait until it hears sound coming to it (with several mics pointing in each direction) and run away from it.  Or just one that hears and runs away.
