Just Another Marble Robot (JAMR)Just Another Marble Robot (JAMR) is a very simple Arduino based, 3-axis robot that you can build yourself as a school project or as a fun project with your kids. This robot will make your marble track much more interesting. Despite being tiny it has all the stepper functionality of a larger robot including a high accuracy. With a ramp-up and ramp-down function it moves much smoother that servo controlled robots. The robot is based on the inexpensive 28BYJ-48 12V stepper motor with the ULN2003 driver that you can buy for around €/$4,- per set. In combination with an Arduino Uno the total cost for this project is around €/$32,-. On this page you will find all the needed information to start building the robot.
