This doesn't seem like a bot designed for speed though; It seems more like a slow, clumsy (?) multipurpose bot like e.g. in futuristic homes lol

With regards to the bot design:

-Minimalist and clean as a whole, design seems to flow well together

-Spenner brought up a good point with the lower ribcage, if its not too late you might want to extend it a little, exposing more of the steel "ribs". While I'm at this, if I'm gonna be super nitpicky I don't see how the torso/waist is actuated (?)

-Is it just me or you got the knee joint backwards? It seems that the front has more space to bend, while the rear has that protrusion that stops it bending further like (a reverse-jointed mech). Watching your animation as the bot bends, it seems that protrusion unrealistically clashes with the thigh but its conveniently hidden from the angle of the camera

-Besides that the articulation overall seems to be well thought out. Very minor thing would be that the neck design seems like its not made for sideways rocking motions. Styling on "gauntlets" means that it can't thrust its palms forward, or do pushups (unless it uses its fists rofl)

-Pardon me if I'm delving too deep in the realism of this, but be a little careful with the way the outer shell is designed. Realistically a real robot like this would have seam lines/parting lines in the shell so that they can be taken off or manufactured more practically (e.g. a parting line running between the front and back shells of the torso). It seems from this design that the parts are fabricated in hollow shells, and then "slipped" onto the internals, which is still plausible from your current design fortunately

-If you plan to make an animation with a few of these bots in it you might want to make slight head variations for each to make them more distinctive, or small alterations of styling (e.g. two wires protuding from the back instead of one, decaling/markings on the shells, different curve stylings)

(gotta say I'm a sucker for the reflective finish though. Raytraced?)
