Let's Make Robots!

Want to make my first robot!

Hello there..

 

I`ve never made any robots, but i really want to try to do that atleast once and if i would like it i could continune doing that :)

 

Just. i was wondering, could anyone help me to chose the easyest object avoiding robot to make ?

And what about the parts, I can get them only on e-shops ?

Thanks.
