BrickPi Book Paper Reader

The biggest trick lies with the motor connected to the wheel. The motor is not fixed to the platform but can rotate freely from the point that it is connected to the platform. This is pretty important because it keeps the pages pressed down so that the wheels can get a grip on the page. Another important thing to do is to rotate the wheel only for the time it takes for one page to come out of the wheel and then rotate the wheel back so that any extra pages which might have been pulled up are brought down.

In the Dexter Industries Github repo, there is a test code called arm_test.py to help you calibrate the arm for perfect movement. Just connect the motor to Port A of BrickPi and change the values of ‘speed_roller’,’speed_arm,’t1′ and ’t2’, until you get flawless movement.
