A4988 and NEMA17
Hi, I'm trying to build a balancing robot like B-Robot. A bought the same Driver and Motor. (This is the motor data sheet: https://s3-ap-southeast-1.amazonaws.com/...20RevA.pdf).

This is the minimal robot : https://dl.dropboxusercontent.com/u/5096...G_0956.jpg

The wheels are 6 cm of radius and we use a poll A4988 driver.
The connection from the motors to the drivers are these:
2B : Blu
2A : Red
1A : Black
1B : Green

The VMOT is 19V

The problem is :
The motor doesn't have enough torque to move the wheel quickly. But Your robot had fast acceleration
The motor is locked
