I don't remember where I saw it, but the legs in the pic are actually prototypes for Stinger(possibly), and Galvatron does't have legs yet(scientists are still working on him).

 

I just want to point out the the so called CGI markers are "only" on the white Bee legs. If you look at the trailer in slow motion, you'll see that the markers that are seen are in "both" white Bee legs and there are no markers on the Galvatron body at all.

 

Here's what everyone is seeing. Its Bumblebees legs from the first movie with a bit of his torso being shown as well.



Here's the same legs on a statue of BB also circled what you see in the trailer.

 

So do you think its the white camaros body being built or is it more of a background prop in a warehouse where they assemble the robots?

 

It really would not surprise me if it turned out to be the first stinger before they decided to go to the updated Pagani model. But it could just as easily be a back ground prop an nothing more.

 

I doubt if it's a Hazmat suit. It's a clean suit so the human doesn't contaminate the robot. Of course the studio will re-use props and what ever they can to save time and money.

 

I've worn Hazmat Suits and Firefighter Bunker Gear. The Hazmat suit is actually comfortable on a hot day when the fresh supply line or the SCBA is in use.
Bunker Gear both keeps heat out and by default, heat in. After 5-10 minutes in a 500F structure, the air from the SCBA gets awful hot to breath.

 

They also is that symbol for testing parts of vehicles or cars or on dummies, it means that it is a test dummy , those are test dummy legs and not the final product, bam sign solved

 

OMG! Giant Bumblebee sized crash test dummy for a BeeMobile!!! JK. Haha!
