I got a Blue for my birthday last year, So... here's my review and observations.
She can not walk unless in direct control mode, or training mode and given the command, but is the fastest by far of all of my robotic dinosaurs. ( ...not saying much, as I don't have a zoomer, but still ) She has wheels on her feet almost like rollerblades. Somehow her touch sensors work through solid plastic, and she has one on her head and one under her chin. The remote is needed even when autonomous, because you "feed" her by holding a button and making a tossing gesture with the remote, simulating feeding her a dead rat as seen in the film. She can see with two motion sensors in her nose holes, and hear through small holes on her neck.She also has two sensors that seem to be for motion on her chest, which are not listed in the instructions, my best guess would be to guard against falling off a table.
She is covered entirely in plastic, with a stiff rubber for her hands, claws and the tip of her tail.
Training mode: She comes with instructions telling you what to do, you click a button on the controller and make a gesture with the remote and hopefully she will turn, move, roar or attack, depending on the command. Then you reward her with imaginary food. At first you can only have her do simple commands, like turn around. Over time this will level up and unlock the ability to do more, until you reach the final one "attack".
Direct control mode(s): Unlike Robotraptor/Roboreptile, she has two modes of direct control One which is for walking/skating around and another for her eyes ( open and close as well as looking around ) and roaring.
Autonomous mode(s): Three modes for this, one friendly, one neutral and one hostile. she will make sounds, get hungry and react to petting while like this, and kind of do her own thing ...as long as that doesn't involve walking.
Her battery is internal and would be difficult to replace, she comes with a charger, a remote and her box transforms into a decently large area for her to walk if your floor is a rug. Also a cable to connect to computers for software updates.
The remote is... pretty much a Wii nunchuck. it's the same size and shape as one, but with more buttons. the stick is for direct control, two buttons cycle her modes, one is for food and one is a clicker, like Owen has in the films.
She has some of the classic JP raptor sounds as well as several new to the two Jurassic World films.
She is roughly the size of a Roboraptor, but not quite as long, and she is much less.... chaotic than they are, due to not being able to freely walk.
Interestingly enough, I tested the clicker with Roboraptor and they actually respond to it. It's not infrared or anything, it makes a sound, and they will turn or charge in the direction of it. Roboreptile will not.
