I've been known to dabble in RPing from time to time and there is no shortage of folks that love to RP within the various universes of Transformers. However, I keep seeing certain terms come up again and again in different players' prose.
Being into actual machines and robots and knowing a thing or two about mechanical engineering the use of these terms really rubs me the wrong way.
In particular the ones that really agitate me when I see them in use are "mech" and "servo". People have been using "Fem" for ages to denote a female based Cybertronians. It makes sense, "fem" --"female" or "fembot". And I guess Players want to have some sort of Cybertronian analog for "male", but people... "mech" isn't it. A "mech" is a piloted exo-frame. Or a giant robot that isn't alive and requires a pilot if you like. It has nothing to do with gender other than it's a short word like "male" and starts with an "m". If anything I think people should use "bot". Think about it, humans use "female".. fe-male. If Cybertronians were to use "fem" as short for "fembot" then the "male" analogue in that word is "bot".
The other one, "servo", grinds my gears so to speak. The reason is because I actually know what a servo IS. In terms of ServoMotors they are basically motors that have feedback sensors in them allowing them to report back to the system controlling them so they can adjust output of force. If you were to make a robot finger you would put a servo at each joint so one finger might have 3 servos. It has NOTHING to do with hands, or gripping, or anything hand like. Stop using it as a replacement for "hand" in your writing, it makes you sound stupid. It would be like saying "he looked down at the weapon clutched in his knuckle". In industrial Robotics robot arms are outfitted with a wide variety of tools depending on the task. The most common are "grippers" and "manipulators" which are more or less a claw or 2 fingered hand. Either would be fine replacements for "servo" in your writing, though they don't have the same "feel" as "hand" do they? Nor would "Manipulator Servo Array" and would likely confuse your readers but it would be more accurate. Just use "hand", it makes sense and doesn't sound like you're trying to be clever with terms you don't understand.
As a freebie, you can use "actuators" anywhere you would normally use "muscles" and it will make sense for a robotic species. Actuators come in electrical, hydraulic, and pneumatic systems and are basically robot muscles so you're good there.
