Esky that follows me, noob where to start?

Hi all

I’m wanting to make something like this;

But, I have no idea about robotics and know only simple programming of smart relays.
I would also like to integrate remote control as well into the transmitter.

I have electrical knowledge but not really anything about microcontrollers.

If possible I would like for it to carry up to 40kg in an outdoor area.

I know this may be ambitious but I’m willing to learn and not really working to a timeframe.

I strongly… strongly advise

I strongly… strongly advise you to start by clicking at “Start Here” in the top menu.

Thanks maxhires

I think if I break each part down I’ll get there. I’m going to buy some bits and pieces and start playing around. Have you got any good links on hacking the sensors? I haven’t been able to find much yet?

I think I will be going thru the ‘start here’ process first.

SEPARATE ultrasonic transmitter and reciever

I’m wondering if this http://www.youtube.com/watch?v=cUFNgfTP2vM will work for my direct measurement ‘call’ system.

OR i could hack the PING sensors, not sure which is easier?
