i finally made it, i made it to transform :D. here is few pictures of animation but i have not rendered animation yet and sorry for bad quality, but hope youlike it 
Looks good. I’d like to see an animation of its transformation.
Looking pretty good! I think the head looks way to big, is there a reason you have it that way? im guessing it doesn’t transform? it looks like the front tires might be to small as well.
Looking nice. will this be transformed to the car next to it?
Love it! Extremely awesome!
Very cool. I like it.
Probably took a long time to get this far. Now you just gotta texture it and spend more time 
yeah, although this probably won’t need a lot of textures, as most of the detail is modelled.
Looks really good
thanks everyone, here is few pictures of my textured robot. i know that i am not very good at texturing, rendered cycles (200 passes) 
That is very good modelling. I agree about the weel on the robot form , they are too small. Looking forward to see your final result and your animation.Continue the good work.
thanks fatal error
Looks epic!
