Basics of the LEGO Power Functions Servo Motor (88004): why does it exist? [English|HD]

The LEGO Technic Power Functions System had a special motor: the servo motor. It was a special motor only beeing used for steering. But why do we need a special type of motor for steering?

Thanks for the very informative video. I know the PF servo motor is only used in 3 sets. I will soon have 9398 4x4 Crawler. If a power supply WITHOUT variable voltage is used, is there any way to rotate the servo to other than +/- 90 degrees? If not, I suppose that's a hard steering (all or nothing). I'll know soon enough when I receive my 9398, which is controlled via IR Receiver (V2), but the remote controller does not have variable position, so it's the same problem. Perhaps it's time to just move on to Powered Up...

Great video, clever stuff👍😊

I'm new to this, but wondered if I could use the servos in the garden to control railway points?

Any thoughts or ideas gratefully received 👍😊🤞

Hi, very informative. I have a question is it possible to have more than one Tech hub connected to one project eg: eight motors

[j.smalik]

Hi if the hub is used, any way we can connect the monster motor, as it has the brick connector

[denisrosas]

is there a way to control the chinese version of servo motor with a remote control?

Hello,

IS it possible to change the rmp of the servo motor?

How can I make a lego motor turn 360 degrees every time and stop in the same place?

Can we operate or give power to 88004 through 8884 with remote control ?
