How do I get electricity to work.

if the parts are not directly connected to the fuel tank ("battery" selected as type) - it might need the "fuel line" selected on all the parts between your robotic parts and the battery fuel tank...like if the battery tank was on the top of the rocket, and a rotator was on the bottom part, just turn the "fuel line" setting to "on" in the settings of those 2 parts, and every part between them, and they should operate - same for monopropellant and rcs, or xenon tank and ion engine

Thanks, sorry, I'm quite new to the game.

Robotic parts are controlled by sliders by default. There is a plus button at the bottom left of the screen (during flight) that will allow you to use the slider, use that @LordElectron

Robotic parts still don't work, any ideas to get them working

Thanks
