Let's Make Robots!

geared servos and stepper motors and plain servos

Hi,

 I've just joined couple minutes ago, searching the net came accross the drummer bot and then this site. First, greetings to all the beautiful minds here :)

 

ok. here goes:

1. what is the difference between a geared servo, stepper motor and a plain servo like ones found in simple toys or cooling fans.

2. Can anybody recommend a book on electronics or robotics generally that will get the unitiated started?

 

I used to have an nxt kit, which is now lost, which I believe is the best toy ever but not as flexible when you have some wild ideas for a project. So any ideas and starters are much appreciated.

 

cheers,

 

 

and another thing, how do you control position. how would it be possible get feedback on the position of the servos at a given time?

I'd recommend:

Absolute Beginner's Guide to Building Robots (0789729717)

Programming Robot Controllers (0071408517)

Building Robot Drive Trains (0071408509)

Those are ISBNs for UK editions you may get local editions cheaper.
