Description
You got your two types of servo, see: your “regular” servo turns to the angle you ask for (by using a PWM signal). Your continuous servo turns at the speed you tell it to. It’s like this:
| regular servo | continuous servo |
| angle 0 | full reverse |
| angle 90 | don’t move |
| angle 180 | full forward |
I’ve used two continuous servos to build a line following robot with differential steering.
