The mobility is very good. I will say that we have trained professional stilt walkers in them, and those guys really bring them to life and get around real well.
Unfortunately these are only at the Universal park in Singapore. I can't confirm when or if the Hollywood Universal will get them yet.
A few interesting notes;
Optimus Prime is just over 9 feet tall, Bumblebee is just over 7 feet
Each costume weighs less than 85 lbs.
Both costumes are made of carbon fiber
The actual ILM digital animation models were used to CNC the patterns (especially Bumblebee)
Used the same automotive paints that were used on the film cars.
Thanks for all the comments! Our team worked hard on these, and it was a different kind of challenge for us. We normally don't create these type of characters.
