New motors
The motors was changed to servos. The step motors have big disadvantages.
- They require a lot of power (more than 1.5A)
- When step motor run at slow speed - it vibrates. And everything that connected to it vibrates. The vibration is very powerful. It can open screws.
And 2 additional ultrasonic sensors was added at the sides. The software is on it's way.
