(Sin alpha)^2 + (Cos alpha)^2 = 1
Hi guys!
I present you my sixth robot. It`s from plywood and it´s very light robot. 
It can be moved in the middle.

He receives four strong (12kg/cm) servos modiefied for continuos rotation and four servos for control.
It can dance "sine or cosine" and it can overcome various obstacles
I wanted to actually write chalk "I Like LMR", but i need more time for programming.
Here some pictures:
