For context, my intention is to imply a character is stiffly-moving, like a machine. A couple of examples I’ve used are “Oscillate” (rather than sway back and forth), “Rotate” (as opposed to turn),”Gyrate” (as opposed to circled), “Extend” or even as a stretch, “Telescope”.
Any additional examples would be helpful even if the associations with machines are tenuous at best.
