Two lego technic servo motor ideas

[Zerobricks]

Just fiddling around and got these two ideas:

1. Servo steering control for trailer:

BAsically the battery box is connected to the trailer's kingpin and it conttrols the steering in the rear electronically. Compared to mechanical systems it has no slack and has far more steering power than regular solutions. But there is a slight time delay.

2. Servo electronic angle limiter:

Sometimes you want to limit how far the servo can turn without forcing it. This works only with PF switch though...

Nice ideas.

I saw somewhere similar idea that someone used for the trailer, but not like this. Great!

I like the trailer idea very much!

Han's Stone Trailer Truck used similar trailer steering setup. Nevertheless, it's a very clever solution!
