First robot idea

I’m new to this website, but have been researching robots for a while, and my ultimate aim is to have a cube shaped robot on 4 wheels which can walk around on its own, and can follow you, with a talking ability if that’s possible, any help would be appreciated. Thanks, smiggle

If you are looking to study

If you are looking to study loki, his data is on his inventor’s website. You can make a robot like what you descibed minus the following by some kits via robotshop, or get started with the LMR robot. If you’ve already done some small bots, a turtlebot or a similar kit might be up your ally. Otherwise, grab a start here kit or the lego nxt and go to town. Talking can be done with an mp3 component or if you want low tech, a buzzer when working with a pickaxe.

Mp3 voice
I have several mp3s I could tear apart, which part is needed?

**Audio amp, **
I also have an ado amp I made in year 8, would that work?
