If you've seen the fourth installment of the Transformers film series - Transformers: Age of Extinction - you may have noticed some star turns from the other "transformer" robots. All told, 13 Kawasaki robots - four different models from two different series - make appearances in the film.
The robots were used on 3 different sets in upwards of 6 scenes, all of which take place at the Chicago headquarters of a corporation called KSI. All Kawasaki robots work in the service of KSI's goal to reverse engineer the good-guy Autobots and bad-guy Decepticons and create the first human-built Transformers.
In one scene a Kawasaki robot model RS06L melts down the head of Ratchet, a beloved Autobot slain earlier in the film. In another scene, two model RS10N robots manipulate Brains, a Decepticon drone turned Autobot imprisoned by KSI to decode Transformers' brains so they can be replicated in the human-created Transformers. In a third scene Kawasaki BX200L robots assist KSI scientists as they probe a dead Transformer for secrets in a sub-zero temperature lab.
The robots' activities at KSI's labs are only a hint at their off-screen capabilities!
