Thanks for chiming in! it mostly comes down to space limitations: Face & Eyes: We pretty much stick to DC motors here because there's just no physical room to squeeze anything else in. Jaw/Mouth: That’s a toss-up between DC motors or servos, depending entirely on how much space we have and the torque needed. Smaller Models: If we're building a smaller dino, space is tight all over, so DC motors are usually the go-to. As for steppers, our team feels they're pretty much outdated for modern animatronics nowadays due to performance limits. Really appreciate your insights—always awesome to geek out over this stuff with someone who gets it!
