I am looking for some suggestions.
My daughter is building the Mars Rover set (go here for the details: http://www.eurobricks.com/forum/index.php?showtopic=98222) for a presentation at school and I told her I would help make it operate by remote control with one of the power function kits. Problem is that it is a lot more complex than I thought. (I have no experience at the expert LEGO building).
I think I can maybe get it moving with a remote, receiver, and simple motor attached to one wheel, but I do not have any idea how to do the steering and don’t know how to move any of the other functions (camera, antenna, robotic arm). see https://www.youtube.com/watch?v=SrGmxwcLcUE
So, to steer, I use a servo?
How do I operate the other things, more servos?
And to move things slowly, do I need complex gearing?
Any suggestions to help me figure out what I need to do and what to buy to easily make this work would be much appreciated.
