Uses for (infernal) robotic arms?

[baldamundo]

Is there actually much point in building a robotic arm in KSP? Like I get that they're cool and all, but is there actually any legitimate use for them that's more effective than just using an RCS tug?

Don't get me wrong, I want to use robotic arms, but I'm just not sure exactly what the point is and if they're worth all the effort. Are they mainly a sort of vanity project done for the fun and challenge of engineering them rather than them actually being useful in-game?

On a space station: Have an arm to maneuver new modules into place without having to use any monopropellant or any other fuel. Electric power is free.

On the ground: Have a crane in a low gravity environment to move/join together modules for the same reason as above

On the ground 2: Have a module based drilling operation with a crane/coupler connecting the power unit, solar panel units, drilling unit, convertion unit, storage unit etc. Makes it easier to build up a very large mining operation with small, easy to bring over, units.

 

Just a few ideas.

I was reading that apparently it gets really buggy if you use infernal robotics to dock things together?

Can definitely see it being invaluable for ground base assembly though
